Evaluation of speech errors in Putonghua speakers with cleft palate: a critical review of methodology issues

[Application of team approach and key techniques of cleft lip and palate]

The development of an expert consensus based on specific domestic situations will provide practical guidance to the efforts aiming at improving cleft care in China. The team approach of twenty-one cleft centers were pooled together, covering pre-surgical orthopedics, primary surgical repair, orthodontic treatment, alveolar bone graft, secondary deformity correction, palatal fistulae repair, the diagnosis and treatment of velopharyngeal incompetence, speech therapy, otitis media management, and skeletal deformity correction. Agreement was achieved among the authors concerning the application of critical surgical and non-surgical techniques. The ambition of this consensus is to introduce more clinicians to the revolution of sequential treatment of clefts, and form the basis for a more comprehensive cleft care manual in the future.

Consonant accuracy in Mandarin-speaking children with repaired cleft palate

OBJECTIVE

To compare the consonant production of Chinese-speaking cleft palate children with perceived hypernasal resonance (PHR) after palatoplasty and those with perceived normal resonance (PNR), and to assess the possible influence of language on articulation.

SETTING

Two hospital cleft lip and palate centers in mainland China.

PARTICIPANTS

Thirty-one speakers were allocated into two groups based on perceptual judgment results of their resonance provided by three speech therapists: one group with PNR (n=20, average age=9.3 years), and another group with PHR (n=11, average age=8.3 years). All participants had no known hearing or cognitive deficits.

INTERVENTION

Articulation was evaluated using two Mandarin Chinese assessment tools, the Putonghua Segmental Phonology Test and the Deep Test for Cleft Palate Speakers in Putonghua. Speaker consonant accuracy was evaluated by two experienced speech therapists.

RESULTS

Compared to individuals with PNR, the PHR group exhibited more difficulties on production of unaspirated consonants, including/b/,/t/,/k/,/ts/,/tʂ/ and/tɕ/, than for aspirated consonants.

CONCLUSION

The distinctive feature of aspiration in Mandarin phonology brought a language specific pattern to consonant production among those speakers with PHR after primary palatal closure.
