Abstract
OBJECTIVES This study aimed to assess the efficacy of Kinesio taping on male patients with mutational falsetto undergoing voice therapy. DESIGN Double blind, randomized, sham-controlled clinical trial. PARTICIPANTS Interviews were conducted with thirty seven mutational falsetto patients. Included 32 participants were randomized and divided into two groups. Two were dropped out due to irregular attendance, 30 participants were included in final analysis. INTERVENTIONS The study group was treated with voice therapy and applications of three different therapeutic Kinesio taping techniques with seven Kinesio tapes four times over two weeks, and the control group was treated with voice therapy, and applied to sham Kinesio taping. OUTCOME MEASURES The values of fundamental frequency, jitter, shimmer, noise-harmonic ratio, maximum phonation time, Voice Handicap Index-10 scores, and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores were recorded at the baseline and after the two weeks. RESULTS There were significant differences between the study group and the control group with respect to the values of fundamental frequency (P = 0.011), jitter (P = 0.041), shimmer (P = 0.036), noise-harmonic ratio (P = 0.003), maximum phonation time (P ≤ 0.001), Voice Handicap Index-10 scores (P = 0.036), and Grade-Roughness-Breathiness-Asthenia-Strain Scale scores (P = 0.007; P ≤ 0.021; P = 0.022; P = 0.002; P = 0.021, respectively) at the end of the study. CONCLUSIONS The study demonstrated that Kinesio taping with voice therapy is an efficient and effective technique for treating mutational falsetto patients.

Abstract
INTRODUCTION Childhood and adolescence are essential stages in the development of voice and speech quality; therefore, it is essential to understand the vocal changes that occur during this period. Frequency-based measurement methods like cepstral measurements stand out among the methods described, which are able to identify fo and estimate the periodicity and noise in the acoustic wave without establishing individual cycles of the sound wave. METHODS Two hundred seventy-one recordings (128 female and 131 male) from children and adolescents aged 5 to 18 years with no vocal complaints were analyzed. Three speech-language pathologists assessed the vocal quality and determined as appropriate for the age. The recordings were divided into six age groups (G1:5-7; G2:8-9; G3:10-11; G4:12; G5:13-15 and G6:16-18 years old). Sustained production of the vowel /a/ were inspected and edited using the PRAAT software. Then, it was extract de Cepstrum Peak Prominence Smoothed (CPPS) using a script in the same software. A Two-way ANOVA was applied to investigate the effect of sex, age and sex*age interaction, followed by Bonferroni's correction for each gender separately. Finally, the Student's t test for independent samples was performed to compare genders within each age group. RESULTS Male children and adolescents from G5 and G6 had higher CPPS measures than G1, G2 and G3 (P ≤ 0.001). In addition, G6 also had higher values than G4 (P ≤ 0.001). There was no difference between age groups in the female group. In turn, sex differences were reported from 12 years of age onwards, with higher CPPS values found for male participants compared to female participants (P ≤ 0.01). CONCLUSION Vocal changes that usually occur from childhood to adolescence are reflected in the acoustic CPPS measure in males, resulting in higher values in the 13 to 18 years old. On the other hand, no changes in CPPS values were observed in the age groups of female participants. Males have higher CPPS values than females and that sex differences are reported after 12 years of age.

Abstract
OBJECTIVES From a human evolution perspective, identifying a link between physique and vocal quality could demonstrate dual signaling in terms of the health and biological condition of an individual. In this regard, this study investigates the relationship between men's body size, shape, and composition, and their vocal characteristics. MATERIALS AND METHODS Eleven anthropometric measurements, using seven indices, were carried out with 80 adult Polish male participants, while the speech analysis adopted a voice recording procedure that involved phonetically recording vowels /ɑː/, /ɛː/, /iː/, /ɔː/, /uː/ to define the voice acoustic components used in Praat software. RESULTS The relationship between voice parameters and body size/shape/composition was found. The analysis indicated that the formants and their derivatives were useful parameters for prediction of height, weight, neck, shoulder, waist, and hip circumferences. Fundamental frequency (F0) was negatively correlated with neck circumference at Adam's apple level and body height. Moreover neck circumference and F0 association was observed for the first time in this paper. The association between waist circumference and formant component showed a net effect. In addition, the formant parameters showed significant correlations with body shape, indicating a lower vocal timbre in men with a larger relative waist circumference. DISCUSSION Men with lower vocal pitch had wider necks, probably a result of larynx size. Furthermore, a greater waist circumference, presumably resulting from abdominal fat distribution in men, correlated with a lower vocal timbre. While these results are inconclusive, they highlight new directions for further research.

Abstract
INTRODUCTION Vocal changes occur across the life span and can be reflected in acoustic measurements. OBJECTIVE To investigate the characteristics of voice production of the Brazilian Portuguese speakers across the life span based on acoustic measures of Fundamental Frequency (fo) and noise-to-harmonic ratio (NHR) and to verify the differences in these measures between men and women. METHODS A total of 526 recordings from Brazilian Portuguese speakers aged 5-93 years were included. Voices from these speakers were judged with normal vocal quality for their age using the G parameter of the GRBAS scale. The recordings were divided into 12 age groups (5-7 years; 8-9; 10-11; 12; 13-15; 16-18; 19-29; 30-39; 40-49; 50-59; 60-69 and, 70-93 years old). Acoustic analysis was conducted, extracting the parameters fo and NHR through Multi-Dimensional Voice Programsoftware. RESULTS For women, there was a gradual decrease in fo from childhood to older age. Older women (60-93 years old) showed a lower fo than age groups up to 19-29 years (P< 0.00). For men, there was a decrease in fo up to the age group of 13-15 years (P< 0.00) and, then, it remained stable. Differences between sexes occurred from 12 years old, with higher fo values for women than men (P< 0.00). The NHR parameter remained stable across the life span for women while higher values for older subjects were found for men (P< 0.04). Regarding sex, men showed a higher NHR value than women (P< 0.002). CONCLUSION Vocal changes occur across the life span and are reflected in the acoustic measure of fo for men and women. The beginning of vocal changes occurs from 12 years old with differences between sexes. The NHR measure was sensitive to indicate changes over a lifetime for men, with higher values for older subjects.

Abstract
OBJECTIVES/HYPOTHESIS The male singing voice through puberty undergoes many changes that present challenges for the singer and choral director. The purpose of this study was to discuss the endoscopic findings seen in prepubescent choir singers. STUDY DESIGN Single-institution prospective study. METHODS Subjects were recruited from the Cincinnati Boychoir and were described as Cooksey stage unchanged or mid-voice I, as described by the Boychoir artistic director. Vocal history was obtained via questionnaire at the initial visit. Subjects with known laryngeal pathologies were excluded. Endoscopic laryngeal examinations were performed using videoendoscopy. During examination, each subject sang four discrete frequencies. Findings of the endoscopic exam were judged by a board-certified pediatric otolaryngologist specializing in pediatric voice. RESULTS We evaluated 28 subjects prior to vocal maturation. Their age range was 8 to 13 years old (mean = 10.2 ± 1.2 years). The singing voice category of all 28 subjects was described as soprano vocal range by the Boychoir artistic director. The subjects had a mean of 1.7 ± 1.1 years in the Boychoir (0-5 years). None reported history of vocal issues or voice problems in the past; seven (25%) subjects had vocal fold lesions seen at one or more frequencies; 24 (85%) subjects had a posterior gap seen at one or more frequencies. Two subjects (7%) had a posterior gap at one frequency, C3 and G3, respectively. Five subjects (18%) had a posterior gap at two frequencies, seven subjects (25%) at three frequencies, and 10 subjects (36%) in all four frequencies. CONCLUSIONS Our study aimed to describe the laryngeal examination of dedicated Boychoir singers prior to undergoing pubertal development and vocal maturation. In elite pediatric singers we found that vocal nodules are common (25%) and are not correlated with vocal symptoms. These findings may suggest that asymptomatic lesions may be more prevalent than previously thought. In these individuals, posterior glottic gap is common and can be considered a normal glottal configuration. LEVEL OF EVIDENCE 4 Laryngoscope, 131:592-597, 2021.

Abstract
OBJECTIVES Puberphonia or mutational falsetto (MF) is seen more in males, and hormonal changes are considered to be among the aetiological causes. Therefore, the aim of this study was to investigate the molecules [G protein-coupled oestrogen receptor 1 (GPER-1), aromatase, 17-beta-hydroxysteroid dehydrogenase (17β-HSD), cyclic adenosine monophosphate (cAMP) levels] related to receptors and pathways in patients with MF. METHODS The study included 30 MF patients and a control group of 30 healthy individuals. Voice recordings were made of the MF patients and acoustic analyses were applied. The serum GPER-1, aromatase, 17β-HSD, cAMP levels and TSH, estradiol, prolactin, progesterone, and testosterone levels were evaluated in venous blood samples. RESULTS In the MF patients, the GPER-1 level determined of mean 3.68 (1.95-4.26) pg/ml, 17 beta dehydrogenase of 5.25 (2.73-6.77) ng/ml, and cAMP of 24.62 (11.62-30.35) ng/ml were statistically signficantly higher than those of the control group (p = 0.008, p = 0.002, p = 0.003, respectively). The aromatase level in the MF patients was found to be 3.48 (2.01-4.91) and the difference between the two groups was not statistically significant (p = 0.067). CONCLUSION The GPER-1, 17β-HSD, and cAMP levels were found to be higher in the MF patients than in the control group, suggesting that they could be of importance in the diagnosis and treatment of MF.

Abstract
ABSTRACT Purpose: to carry out an integrative literature review about the acoustic characteristics of healthy voice production, from childhood to old age. Methods: a bibliographic survey was conducted on the databases PubMed, SciELO, MEDLINE and LILACS, covering the last 10 years. Nineteen studies were found, meeting the proposed criteria, on acoustic measurements: F0 (fundamental frequency), jitter, shimmer and/or noise measurements, in males and females, with normal voices in their different stages of life. Results: the analysis showed that F0 is the most changing acoustic parameter as people grow up and grow old. Its values present gradual fall from childhood to old age in the female population, whereas among men such decrease lasts until adulthood. Jitter, shimmer and noise remain stable throughout childhood and adulthood, while shimmer and noise measurements increase in old age. In the literature, there is no consensus regarding increase of jitter measurements in the elderly. Conclusion: from childhood to old age, in both genders, vocal changes take place which are reflected, especially by F0. There is a scarcity of information on acoustics related to specific populations with ample age range, using the same methodology. The information in this study may guide future investigations aiming to understand natural changes occurring in the human voice, in addition to guiding in the clinical practice.

Abstract
OBJECTIVES The aim of this study was to establish normative data concerning the speaking voice of children and adolescents for clinical diagnostics. STUDY DESIGN Population-based mixed cross-sectional and longitudinal childhood cohort study. METHODS Normative data measuring the speaking voice profile of 1352 male and 1274 female participants aged 6 to 17 years were collected. To evaluate the voice range, five different intensity levels as the quietest voicing speaking voice (Level I), conversational voice (Level II), classroom voice (Level III), shouting voice (Level IV), and again the quietest speaking voice (Level V) were investigated. Multivariable analyses were performed to describe the effects of body mass index, Tanner stage, and singing activity on the outcome variables. RESULTS A clear distinction in frequencies and sound pressure levels between the five different voice levels can be found in both genders. In females the mean fundamental frequency of the conversational voice lowers from 223.3 to 205.8 Hz. In male participants it lowers from 223.3 to 102.3 Hz. The most substantial decrease in the fundamental frequency of the speaking voice in boys occurs at 13.5 years. Girls show an almost continuous decline in their fundamental frequency. Only the Tanner stage showed significant positive relationships with the grade of lowering of the fundamental frequency in both sexes. CONCLUSIONS It was shown that the investigation of the speaking voice using predefined intensity-levels represents a feasible examination for children and adolescents. This study provides reference data on the range and age-adjusted normative values of the speaking voice.

Abstract
Background Acoustic parameters of animal signals have been shown to correlate with various phenotypic characteristics of the sender. These acoustic characteristics can be learned and categorized and thus are a basis for perceivers’ recognition abilities. One of the most demanding capacities is individual recognition, achievable only after repeated interactions with the same individual. Still, class-level recognition might be potentially important to perceivers who have not previously encountered callers but can classify unknown individuals according to the already learned categories. Especially for species with high fission-fusion dynamics that repeatedly encounter unknown individuals it may be advantageous to develop class-level recognition. We tested whether frequency-, temporal-, and amplitude-related acoustic parameters of vocalizations emitted by ravens, a species showing high fission-fusion dynamics in non-breeder aggregations, are connected to phenotypic characteristics and thus have the potential for class-level recognition. Results The analysis of 418 food calls revealed that some components summarizing acoustic parameters were differentiated by age-classes and sex. Conclusions Together, the results provide evidence for the co-variation of vocal characteristics and respective sex and age categories, a prerequisite for class-level recognition in perceivers. Perceivers that are ignorant of the caller’s identity can thus potentially recognize these class-level differences for decision-making processes in feeding contexts.

Abstract
BACKGROUND Current pediatric voice assessment guidelines include instrumental measurements of fundamental frequency (F0) and the perturbation indices jitter and shimmer. In children below 10 years, gender, age, height and weight effects on these parameters have been inconsistently characterized. Recent research in healthy children showed, that differences in habitual speaking voice intensity (voice SPL) under the usual assessment procedure significantly affect jitter and shimmer. These effects were reduced in phonations with controlled voice SPL >80dBA. Reliable measurement methods and description of physiologic influencing factors are essential to identify pathologic voices. OBJECTIVE This cross-sectional single cohort study investigates in children between 5;0 and 9;11 years how gender, age, height and weight affect voice F0, jitter and shimmer in phonations at individually "medium" voice intensity (modeling the usual clinical practice) and with controlled voice SPL >80dBA. SUBJECTS AND METHODS 68 vocally healthy children (39 f/29 m) aged 5;0-9;11 years provided 3 prolonged phonations of/a/at individually "medium" and controlled voice intensity at ">80dBA" (visual feedback, 10cm distance). F0 (Hz), jitter (%), shimmer (%) and voice SPL (dBA) were determined with PRAAT. Gender, age, height and weight effects without and with controlled voice SPL were assessed by descriptive statistics, Analysis of Variance and Linear Mixed Models. RESULTS F0 (Hz), jitter (%), shimmer (%) and voice SPL (dBA) were significantly different in medium voice compared to >80dBA (p<0.01). In medium phonations girls had a higher F0 than boys (girls: 276.7(50.7), boys: 261.5(33.7)), but with >80dBA this difference was only minimal (girls: 328.9(52.2), boys 327.9(51.2)). Mean jitter (0.27(0.10)) and shimmer (4.34(1.68)) were smaller and showed less spread (jitter: 0.5(0.26); shimmer: 9.47(3.47)) with >80dBA. Gender, age, height and weight had no significant effects on F0, jitter, shimmer and voice SPL in both phonation types (p-range=0.42-0.99). CONCLUSIONS Neither without nor with controlled voice SPL there were systematic gender, age, height or weight effects on voice F0, jitter and shimmer. Gender related F0 discrepancies were equalized in phonations with >80dBA. In children below 10 years gender related acoustic voice differences may be mainly linked to behavior, which should be considered in future works regarding physiologic voice development.

Int J Pediatr Otorhinolaryngol 2014; 78:2121-6. [PMID: 25441603 DOI: 10.1016/j.ijporl.2014.09.020] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2014] [Revised: 09/17/2014] [Accepted: 09/19/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Current voice assessment recommendations for dysphonic children comprise instrumental acoustic measurements of the perturbation parameters jitter and shimmer. In healthy adults and children changes in speaking voice sound pressure level (voice SPL) have significant confounding effects on both parameters. In adults these effects were considerably reduced in phonations with controlled voice SPL >80dBA (10cm distance). However, it is unclear if these findings apply to children and if children are able to control for their own voice intensity. OBJECTIVE This cross-sectional single cohort study investigates voice SPL effects on jitter and shimmer in children between 5;0 and 9;11 years phonating at individually "medium" (modeling "comfortable" loudness of the usual clinical protocol), "soft" and "loud" voice and a prescribed intensity level of ">80dBA" (10cm distance, with visual control). Further both their ability to phonate at a prescribed voice intensity level and the effect on SPL related confounding effects were studied. SUBJECTS AND METHODS A total of 68 healthy children (39 f/29m) aged 5;0 to 9;11 years were included. All phonated the vowel/a/for 5s, three times at four defined voice intensity levels (soft/medium/loud/>80dBA) each. Jitter (%), shimmer (%) and voice SPL (dBA) were determined using PRAAT. Voice intensity level effects were assessed by descriptive statistics, Analysis of Variance (ANOVA) and Linear Mixed Models (LMM). RESULTS There were significant differences for jitter and shimmer between all voice tasks (p<.01). Jitter and shimmer were lowest and showed the smallest spread in controlled phonations ">80dBA". 19 children below 7;0 years could not perform the voice tasks and were excluded from the study. CONCLUSIONS This practical study demonstrated a significant effect of voice loudness and task on jitter and shimmer in children. Since the observed confounding effects were large compared to treatment effects, jitter and shimmer may not be meaningful without adequate control of voice SPL. In phonations at ">80dBA" (10cm distance) voice SPL related effects were considerably reduced. However, this assessment protocol was suitable only for children above 7;0 years. Application of this task to future studies of dysphonic children may yield clinically valuable information.

Abstract
UNLABELLED Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children. PURPOSE To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules. DESIGN Diagnostic test study. PATIENTS AND INTERVENTIONS A comparative study was carried out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between 4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out. RESULTS There was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ, shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups. CONCLUSION Compromising of auditory-perceptual (G, R, B and S) and acoustic vocal parameters (jitter, PPQ, shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

Abstract
OBJECTIVE Parameters to distinguish normal from deviant voices in early childhood have not been established. The current study sought to auditorily and acoustically characterize voices of children, and to study the relationship between vocal behavior reported by teachers and the presence of vocal aberrations. METHODS One hundred children between four and 6 years and 11 months, who attended early childhood educational institutions, were included. The sample comprised 50 children with normal voices (NVG) and 50 with deviant voices (DVG) matched by gender and age. All participants were submitted to auditory and acoustic analysis of vocal quality and had their vocal behaviors assessed by teachers through a specific protocol. RESULTS DVG had a higher incidence of breathiness (p<0.001) and roughness (p<0.001), but not vocal strain (p=0.546), which was similar in both groups. The average F(0) was lower in the DVG and a higher noise component was observed in this group as well. Regarding the protocol used "Aspects Related to Phonotrauma - Children's Protocol", higher means were observed for children from DVG in all analyzed aspects and also on the overall means (DVG=2.15; NVG=1.12, p<0.001). In NVG, a higher incidence of vocal behavior without alterations or with discrete alterations was observed, whereas a higher incidence of moderate, severe or extreme alterations of vocal behavior was observed in DVG. CONCLUSIONS Perceptual assessment of voice, vocal acoustic parameters (F(0), noise and GNE), and aspects related to vocal trauma and vocal behavior differentiated the groups of children with normal voice and deviant voice.

Abstract
STUDY OBJECTIVE Investigate the impact of sleep deprivation on vocal expression of emotion. DESIGN Within-group repeated measures analysis involving sleep deprivation and rested conditions. SETTING Experimental laboratory setting. PATIENTS OR PARTICIPANTS Fifty-five healthy participants (24 females), including 38 adolescents aged 11-15 y and 17 adults aged 30-60 y. INTERVENTIONS A multimethod approach was used to examine vocal expression of emotion in interviews conducted at 22:30 and 06:30. On that night, participants slept a maximum of 2 h. MEASUREMENTS AND RESULTS Interviews were analyzed for vocal expression of emotion via computerized text analysis, human rater judgments, and computerized acoustic properties. Computerized text analysis and human rater judgments indicated decreases in positive emotion in all participants at 06:30 relative to 22:30, and adolescents displayed a significantly greater decrease in positive emotion via computerized text analysis relative to adults. Increases in negative emotion were observed among all participants using human rater judgments. Results for the computerized acoustic properties indicated decreases in pitch, bark energy (intensity) in certain high frequency bands, and vocal sharpness (reduction in high frequency bands > 1000 Hz). CONCLUSIONS These findings support the importance of sleep for healthy emotional functioning in adults, and further suggest that adolescents are differentially vulnerable to the emotional consequences of sleep deprivation.

Abstract
BACKGROUND Quality and frequency variability of adolescents' voice, during puberty, in different phonation tasks. AIM To analyze the vocal stability of adolescents in three different phonation tasks using a voice perceptual analysis. METHOD Participants were male students (n = 46 individuals), ranging in age from 13 to 15 years, from a public school in Campinas--SP. Voice samples were recorded using a digital recorder in three different tasks: speaking a sustained vowel /a/, counting from one to ten, and reading. Three voice specialists evaluated stability by means of voice perceptual analysis. For the voice samples that were considered unstable, the Analogical Visual Scale (AVS) of 10 cm was used to estimate the instability level, where zero means absence of instability and ten refers to maximum instability. RESULTS 78.3% of the adolescents presented vocal instability when speaking the sustained vowel, varying from one to nine in the AVS. Only one adolescent presented unstable voice when counting numbers (level = 1). Vocal instability was not observed during reading for any of the participants. Vocal stability varied significantly among phonation tasks and adolescents showed greater instability during the sustained vowel (p<0.0001; g.l = 2). CONCLUSION Counting numbers and reading do not detect vocal instability; the production of a sustained vowel demonstrated to be a better task.

Abstract
A range of acoustic characteristics typically carry information on individual identity in mammalian calls. In addition, physical similarities in vocal production anatomy among closely related individuals may result in similarities in the acoustic structure of vocalizations. Here, acoustic analyses based on source-filter theory were used to determine whether giant panda bleats are individually distinctive, to investigate the relative importance of different source-(larynx) and filter-(vocal tract) related acoustic features for coding individuality, and to test whether closely related individuals have similarities in call structure. The results revealed that giant panda bleats are highly individualized and indicate that source-related features, in particular, mean fundamental frequency, amplitude variation per second, and the mean extent of each amplitude modulation, contribute the most to vocal identity. In addition, although individual pairwise relatedness was not correlated with overall acoustic similarity, it was highly correlated with amplitude modulation rate and fundamental frequency range, suggesting that these acoustic features are heritable components of giant panda bleats that could be used as a measure of genetic relatedness. The ecological relevance of acoustically signaling information on caller identity and the potential practical implications for acoustic monitoring of population levels in this endangered species are discussed.

Abstract
Este artigo tem por finalidade discutir criticamente os aspectos fisiológicos e psicológicos da disfonia funcional psicogênica por puberfonia do tipo muda vocal incompleta, esclarecendo os objetivos da terapia fonoaudiológica e os fatores que podem interferir no prognóstico. O estudo foi realizado a partir de uma consulta sistemática a fontes clássicas e atuais da literatura científica nacional e internacional. Com base nos aspectos abordados, foi possível concluir que a conduta fonoaudiológica fundamenta-se em técnicas que visam à diminuição da frequência fundamental a partir do abaixamento da laringe. No entanto, faz-se necessário um trabalho interdisciplinar, visto que as causas deste quadro são predominantemente emocionais.

Abstract
This 12-month prospective longitudinal study used acoustic analysis to identify phonational gaps in the vocal range of adolescent boys undergoing voice change and to investigate the relationship between the appearance of phonational gaps, weight gain, and changes in speaking fundamental frequency (SF0). Eighteen pubescent boys were recorded producing three descending and three ascending glides over their physiological voice range using the vowel "ah." Recordings were digitized over the range 0-16 kHz and then analyzed to determine both the frequency range and appearance and frequency characteristics of the phonational gaps. Data were plotted against changes in weight and SF0 both as an indicator of pubertal development and to test the hypothesis that changes in weight and SF0 were related to the appearance of phonational gaps. Results indicated that minimum F0 decreased significantly over the time period and phonational gaps increased significantly, but there were no significant changes in maximum F0 or range. Individual data indicated the initial appearance of a lower-frequency gap followed by a higher-frequency gap before the long-term establishment of a midrange gap. At time 5, all boys in the weight range 42.7-44.9 kg had either low- or high-range gaps. The SF0 for this group varied from 117 to 216 Hz. All boys heavier than 54.8 kg had highly variable phonational gaps. SF0 range for this group was 99.5-151 Hz. Transitory low- then high-frequency phonational gaps appeared before the establishment of a midrange phonational gap. In this study, these phonational gaps were associated with certain weight ranges and rapid weight gain, with changes to boys' speaking voices, and with loss of ability to use the mid- and falsetto vocal range.

Abstract
This research on 17 girls (aged 9;9 y to 16;11 y) singing in an established choir was focused on two issues: 1) the variety in physical and vocal development using Gackle's model, and 2) the matching of vocal demands and abilities. Developmental and acoustical data on the speaking and singing voice revealed considerable variation between individual girl singers. The model was greatly applicable. However, all girls had a greater total singing range, mainly in favour of the lower tones, and 11 girls used a lower speaking fundamental frequency. A third of the girls met the vocal and developmental features of their stage at a younger age. Next the lower limit of the frequency range of all girls was several semitones below the lowest notes of the pieces being worked on at the time of the experiment. However the upper limit of the pieces coincided with or exceeded their upper frequency limit.
