| 摘 要： | 口鼻流信号是一种重要的言语生理信号,是以传统语音学的研究成果为框架,在Matlab环境下设计并实现口鼻音声学分析平台,提出了包括口鼻音能量、时长、鼻音度、口鼻音共振峰在内的一套鼻流信号参数,设计了口鼻流信号的标注方案,实现了口鼻音参数的批量提取和保存.平台的实现不仅可用于语音学的发音研究,而且也为语音信号处理和言语工程的研究提供了实用的工具.

| Abstract: | The oral and nasal flow signal is an important physiological signal of speech.Based on the framework of traditional phonetics research,the acoustic analysis platform for nose and mouth was designed and realized under the Matlab environment,a set of nasal flow signal parameters(such as the energy and formants of oral sound and nasal sound,duration,nasalance) were also proposed,the labeling programs of the nose and mouth flow signals had been designed,the batch process of extraction and preservation parameter... |
