【摘要】：目的运用McGurk效应范式材料,探究唇读对听障儿童语音识别的帮助作用。方法实验组选择双耳重度语前聋且双耳接受助听器补偿的儿童36例(10~12岁,平均11.82±1.54岁),对照组为听力正常儿童36例(10~13岁,平均11.23±1.75岁)。McGurk效应范式测听材料由音频和视频组成,音频包括/ba/、/da/、/bi/、/di/、/bu/、/du/6个刺激音,视频内容为6个音发音时的完整图像资料,经软件处理,在纯听、视听一致、视听不一致三种条件下,测试两组受试者的听觉反应正确率。结果实验组在纯听、视听一致、视听不一致条件下的听觉反应正确率分别为71.23%±19.20%、96.13%±7.10%、11.12%±16.20%,对照组分别为93.15%±10.02%、96.21%±11.12%、54.03%±23.41%,两组受试者听觉反应正确率均依次降低。视听不一致条件下测听时,正常儿童听觉反应所占比例(54.04%±23.23%)显著高于听障儿童(11.47%±16.32%)(P0.05)。结论视听结合是最佳聆听条件,唇读对听障儿童语音识别有帮助作用。
[Abstract]:Objective to explore the effect of lip reading on speech recognition in children with hearing impairment by using McGurk effect paradigm. Methods 36 children with severe binaural preverbal deafness and hearing aid compensation were selected in the experimental group. The average age was 11.82 卤1.54 years old. The control group consisted of 36 normal hearing children aged 1013 years and an average of 11.23 卤1.75 years old. McGurk effect paradigm audiometry materials consisted of audio and video. Audio frequency included / / / r / r / r / r / r / 6 stimuli, and the video content was the complete image of 6 sounds, processed by software. Under three conditions of pure listening, audio-visual consistency and audio-visual inconsistency, the correct rate of auditory response was tested in the two groups. The correct rate of auditory response was 71.23% 卤19.20% 卤7.10% 卤11.12% 卤16.20, respectively, and that of the control group was 93.15% 卤10.02% 卤11.12 2% 卤23.43% 卤23.41%, respectively. The correct rate of auditory response in both groups decreased in turn. The proportion of auditory response in normal children (54.04% 卤23.23) was significantly higher than that in children with hearing impairment (11.47% 卤16.32). Conclusion Audio-visual combination is the best listening condition, and lip reading is helpful to speech recognition of hearing-impaired children.
