摘要
目的探讨听障儿童普通话双字调"去+去"连读变调的声学特点。方法比较60名听障和60名健听儿童普通话双字调"去+去"连读时基频最大值,最小值,调域,拟合斜率等声学参数,并进行统计分析。结果(1)两类儿童基频最大值F0max单发位置显著大于前去(P<0.05)和后去(P<0.01),且前去的F0max显著大于后去(P<0.01);(2)听障儿童基频最小值F0min在单发和后去位置均显著大于健听儿童(P<0.01),前去位置两类儿童的F0min无显著性差异;(3)听障儿童的调域F0(max-min)显著小于健听儿童(P<0.01),两类儿童调域F0(max-min)单发位置显著大于后去(P<0.01)和前去(P<0.01),且后去的F0(max-min)显著大于前去(P<0.01);(4)听障儿童拟合斜率F0K前去位置显著大于健听儿童(P<0.01),单发和后去位置两类儿童的F0K无显著性差异。结论听障儿童和正常儿童一样,"去+去"连读时会产生连续变调现象,表现出接近于成人去去变调发音的走势。但听障儿童去去连读的能力显著落后于正常儿童,表现出后去终点基频较高、调域偏小和协同发音不经济等现象。
Objective To explore acoustic characteristics of Tone4+Tone4change for preschool children with hearing impairment.Methods Tone acoustics parameters were measured between60normal children and children with hearing impairment from age3to5years old.Results(1)Both hearing impaired and normal children showed F0max in monosyllabic tone4was significantly greater than that in former tone4and latter tone4(P<0.05,P<0.01),and F0max in former tone4was significantly greater than that in latter tone4(P<0.01).(2)F0min of hearing impaired children in monosyllabic tone4and latter tone4were significantly greater than normal children(P<0.01).There was no significant difference inF0min in former tone4for both groups of children.(3)F0(max-min)of hearing impaired children was significantly smallerthan normal children(P<0.01).F0(max-min)in monosyllabic tone4was significantly greater than that in former tone4and latter tone4(P<0.01,P<0.01),and F0(max-min)of tone4in latter tone4was significantly greater than that in formertone4(P<0.01).(4)F0k in former tone4of deaf children was significantly greater than normal chindren(P<0.01).Therewas no significant difference in F0k in monosyllabic tone4and latter tone4for both hearing impaired and normal children.Conclusions Both hearing impaired children and normal children will change their tone when pronouncingtone4-tone4words,and exhibited adult-like pitch pattern.However,the tone4-tone4pronunciation capabilityfor hearing impaired children were far behind from normal children and showed lower F0minin in latter tone4,smaller F0(max-min)and uneconomic co-articulation.
