The Function Design of Nasal Flow Signal Analysis Software

Nasal flow signal is a kind of important physiological signals, the framework of this article is based on the achievements of traditional phonetics, we design and relies nasal acoustic analysis platform in the Mat lab environment. Proposed a set of nasal flow signal parameters which including nasal sound energy, oral sound energy, duration, nasal degrees, nasal formant etc. In this paper, we introduced the use of nasal flow software, designed the labelling scheme of nasal flow signal, and achieve batch extraction and preservation of nasal sound parameters.
