Function Design of Oral and Nasal Flow Signal Analysis Software
Yonghong Li · Journal of Northwest University for Nationalities · 2009
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 parameters have realized.The platform can not only be used to achieve the phonetic pronunciation of research,also provides a useful tool for speech signal processing and speech engineering research.
