Abstract:
Objective:To investigate the effect of hearing on consonant discrimination in postoperative cleft palate patients.Meth-ods:30 subjects after surgery of cleft palate were examined for hearing and evaluated for speech,error frequencies of consonants were counted.According to the Chinese tone frequency and intensity distribution and measurement table of dysarthria in Mandarin,hearing and speech were divided into 3 ranks respectively.Spearman rank correlation analysis was used to determine the relation of consonant discrimination with hearing.Results:Higher error frequency of consonants (form high to low)were [t],[ts],[k],[],[s],[t] and [k'].There was close correlation(P ＜0.05)between hearing and discrimination of consonants including [t],[t'],[k],[k'], [t],[t'],[],[ts],[ts'],[s],[t],[t'],[]and [],while the discrimination of consonants [b],[m],[f]and [n]showed no significant correlation with hearing(P >0.05).Conclusion:The hearing of postoperative cleft palate patients affect the consonant discrimination that mainly in the high frequency region,while low and middle frequency consonant discrimination have no influence. Other feedback channels need to be considered in speech training for high frequency consonants.
