Vowel's Nasalance and Contact Quotient in Children with Hearing Loss
Abstract： Objective To investigate the vowel's nasalance and contact quotient (CQ) in children with hearing loss. Methods 57 subjects were divided to 3 groups: profound hearing loss children with hearing aids (HA, n=19), profound hearing loss children with cochlear im-plant (CI, n=19) and children without hearing loss (n=19). With the help of NV and electroglottography (EGG), the subjects' nasalance and CQ were recorded when they said/a/,/?/,/i/,/o/,/u/. Results There was no significant differences among the 3 groups on nasalance (P>0.05). There was significant difference among 5 vowels on nasalance, ranked as/u/,/o/,/?/,/i/, and/a/(P<0.001). There was significant dif-ference among 3 groups on CQ, ranked as HA, normal, and CI group (P<0.001). There was significant difference on CQ among 5 vowels, ranked as /i/,/u/,/?/,/o/, and/a/ (P<0.001). Conclusion The voice and resonance should be assessed before speech therapy, which the speech therapy starts from the most correct vowel for children with profound hearing loss.
