Abstract:
Objective To investigate the effect of final vowel types on the voice onset time(VOT)of differ-ent stops in children with hearing impairment,and to provide a basis for the acquisition and correction of stop sounds.Methods A total of 22 hearing-impaired children aged 3~6 and 22 children with normal hearing were ran-domly selected-18 consonant-vowel(CV)syllables composed of 6 stops and 3 single finals were recorded,using first tone.Using Praat 6.1.29 software to analyze and extract the stops VOT.Two-way ANOVA was used for each stop,the dependent variable was VOT,and the independent variables were hearing status and final type.Results Children in the hearing-impaired group had articulation errors in/t/,/g/,and/k/.Hearing status had significant effect on the main effect of plosives/g/,/p/,/t/,/k/(P<0.05),and the VOT of slurs/g/,/p/,/t/,/k/in the normal hearing group significantly greater than the hearing-impaired group(P<0.05).The main effect of finals on the VOT of the stops/b/,/p/and/t/was significant(P<0.05).Hearing status and final type had an interac-tive effect on the stop/t/,and the simple main effect showed that the difference in VOT of/ti/between the hear-ing-impaired group and the normal hearing group was greater than that of/ta/and/tu/.Conclusion The stops/g/,/p//t/,/k/VOT of hearing-impaired children are smaller than those of with normal hearing.The difference in VOT of/ti/sound between the hearing impaired group and the normal hearing group is greater than that of/ta/sound and/tu/sound.In the teaching of the initial/t/sound for hearing-impaired children,we can start with/ta/and/tu/with less difference,and the/ti/sound is consolidated later.Pay attention to breathing and oral exercise training,to lay a good foundation for clear pronunciation.
