由于辅音的发音难度远大于元音,因此构音障碍儿童辅音的发音偏误率非常高。在对11名构音障碍儿童1554人次的普通话和沪语样本分析发现:从发音方法看,样本中以塞音/擦音/塞擦音的区别偏误比例最高,其次为浊音/清音的偏误,再次为送气/不送气的偏误;从发音部位看,样本中以舌根音的失误率最高,其次为舌尖前音和舌面音,再次为唇齿音,而双唇音和舌尖中音的偏误率最低。虽然舌尖后音的偏误率高达53.41%,但其只存在于普通话音系中。另外,构音障碍儿童还存在部分辅音声母的脱落。究其原因,是由于构音障碍儿童的社会认知能力差而造成交际目标低下、音系认知能力不足,以及因发音器官紧张度不够造成的构音功能和自我监控能力不足。
Because consonants are more difficult to pronounce than vowels, consonants of dysarthria have a very high error rate of pronunciation. An analysis of 1554 Chinese and Putonghua samples of 11 children with dysarthria found that the most common difference between the sample sansepi / soprano / soprano and the soprano soprano was the voiced / unvoiced error , Again as the air / not aspirated error; from the pronunciation site, the sample to the tongue root the highest rate of error, followed by the tongue anterior and lingual tone, once again for the lips, and bilateral lip tone and tongue midrange partial The lowest error rate. Although the error rate of the tongue after the sound as high as 53.41%, but only in Mandarin dialects. In addition, dysarthria children still exist some consonants consonants off. The reason is that children with dysarthria have poor social cognition, which leads to low communicative goals, lack of phonological cognition, and lack of ability of phonetic transcription and self-monitoring due to lack of pronunciation organs.
