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。三名正常人和三名听力受损的受试者发出爆炸性的VCV音节。对VCV音节语音进行分析，提取语音参数。参数包括基音、最大部分自相关系数（PARCOR）、用于线性预测分析的声源幅值、语音功率、倒谱距离、声谱图、线性预测谱（LPC）谱和线谱对（LSP）系数。从声谱图和LPC谱估计了第一、第二和第三格式轨迹。它从爆炸辅音到下面的元音的转换表明了炸药的发音是否正确。元音的学习阶段在第一种和第二种格式中。然后在这些声学参数中找到韵律和浊音（不浊音）的学习阶段。针对听力障碍受试者的语音学习阶段，研究了以VCV音节语音释放的下一口气。炸药的学习阶段体现在最大呼吸速度（U_<pm2>）、测量U_<pm2>的方向（rheta_<m2>）、下一个元音开始到U_<pm2>部分在辅音-元音过渡的持续时间。然后找到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.
