The study of speech and the breath considering the learning stage of pronunciation

本研究结合语音学习阶段，对语音的声学参数和呼吸的速度波形进行了研究。三名正常受试者和三名听障受试者发出爆炸性的VCV音节。对VCV音节语音进行分析，提取声学参数。这些参数是基音高、最大偏自相关系数(PARCOR)、用于线性预测分析的声源的幅度、语音功率、倒谱距离、声谱图、线性预测编码(LPC)谱和线谱对(LSP)系数。从声谱图和LPC谱中估计出第一、第二和第三种格式轨迹。它从爆炸性辅音到紧随其后的元音的过渡说明了爆炸物发音的正确与否。元音的学习阶段分为第一和第二两种形式。然后在这些声学参数中发现韵律和清(清)音的学习阶段。其次，结合听障受试者的语音学习阶段，对听障受试者进行VCV音节发音的呼吸放电研究。炸药的学习阶段是在最大呼吸速度(U&lt；PM2&gt；)，测量U&lt；PM2&gt；的方向(Rheta_&lt；m2&gt；)，以及从下一个元音开始到U&lt；PM2&gt；在辅音-元音转换的部分之间的持续时间。然后找出呼吸控制的学习阶段。

This research studies acoustic parameters of speech and the velocity wave form of breath considering the learning stage of pronunciation. Three normal and three hearing impaired subjects pronounce explosive VCV syllables. The VCV syllable speech is snalyzed, and acoustic parameters are extracted. The parameters are pitch, the maximum partial auto-correlation coefficient(PARCOR), the amplitude of the sound source for linear predictive analysis, speech power, cepstrum distance, sound spectrogram, linear prediction cording(LPC)spectrum, and the line spectrum pair(LSP)coefficient. First and second and third format locus are esimated from sound spectrogram and LPC spectrum. Its transition from the explosive consonant to the following vowel shows whether pronunciation of explosives is correct or not. And the learnig stage of vowel is found in the first and second format. Then the learning stage of prosody and voiced(unvoiced)sound is found in those acoustic parameters. Next breath discharged with VCV syllable speech is studied for hearing impaired subjects considering their learning stage of pronunciation. The learning stage of explosives is found in the maximum velocity of breath(U_<pm2>), the direction(rheta_<m2>)where U_<pm2> is measured, and the duration between the beginning of the following vowel and the portion of U_<pm2> at consonant-vowel transition. And then the learning stage of the breath control is found.
