Through the experiment results, in different phonation model, analysis the properties of glottal vocal efficiency, vocal folds vibration, and voice source.

我们在对嗓音—呼吸系统进行自动分割与分段特征表达的目标指引下，建立了具有国内一流水平的嗓音声学实验室；从概念上对嗓音—呼吸系统重新划分，以声门为中心分别建立去耦合和弱耦合条件下的嗓音—呼吸系统和肺胸系统数学模型；采用离体犬喉作为声带振动的物理模型，对数学模型进行完善与证实；采用盲解卷技术在去耦合和弱耦合条件下，提取上下声道传递函数、嗓音源和发声效率，研究上下声道去耦合和弱耦合条件下不同发声方式与状态对发声效率的影响。

Constant value of vena contracta coefficient has been employed in the well-used quasi-steady models for computing the nonlinear acoustic impedance of the orifice. However, this nonrealistic assumption degrades the accuracy of the theoretical models.

常用的小孔声学非线性效应的准定常模型采用不随声强变化的vena收缩系数，这种不合实际的假设影响了非线性声阻的计算精度。

The history and current situation of research in speech recognition are proposed all-sidedly and systematically. We probe into such topics about acoustic features, phonetic features, phonologic features and auditory perception in terms of related theory and disciplines. Furthermore, we summarize and analyze focus in current theoretical and technical aspects of speech recognition and immediately put an insight into challenge to speech recognition presently, even in a long time.

论文全面、系统地介绍了国内外语音识别的发展历史和发展现状，结合相关学科的知识，分析了语音声学特征、语音学特征、音系学特征及其语音感知等有关问题，分析并总结了目前语音识别理论和技术实现方面的研究重点以及目前、甚至在相当长的时期内语音识别面临的挑战。

Many studies have observed that several articulatory gestures in speech production and their acoustic output tended to be strengthened at prosodically prominent positions; however, the relationship of tonal perturbation of stop consonants and the voice quality with the prosodic hierarchy have not been explored yet.

中文摘要根据过去研究指出，语音的发声动作与声学表现会在韵律显著的地方增强。然而，针对韵律与子音产生的语调扰动以及音质的关系方面的研究甚少。

IsraelNN.com The Seismologic Division of the Ministry of National Infrastructure's Geophysical Institute will attempt to simulate an earthquake in the southern Negev on Thursday. The experiment, financed by the U.S. Defense Department, is a joint project with the University of Hawaii and is part of a scientific project intended to improve seismological and acoustic readings in Israel and its environs, up to a 1,000 km/621 mile radius.
