The Function Design of Oral and Nasal Flow Signal Analysis Software
The oral-nasal flow signal is an important physiological signal of speech, this paper based on the framework of traditional phonetics research, designed and realized the acoustic analysis platform for nose and mouth in the Matlab environment, proposed a set of nasal flow signal parameters such as: the energy of oral sound and nasal sound, duration, nasalance, formants of oral sound and nasal sound, designed the labeling programs of the nose and mouth flow signals, realized the batch process of parameters by the extraction and preservation. The platform can be used to achieve not only the phonetic pronunciation of research, but also provides a useful tool for speech signal processing and speech engineering research.
