Respiratory signal is an important physiological speech signal, which plays an important role in the study of multi-modal of speech. But there is still lack the software with the function of respiratory signal processing. Thus, based on a large number of analysis and in-depth research, this paper puts forward a set of systemic respiratory signal parameters, and carried out a detailed definition. Designed a respiratory signal analysis and parameter extraction platform which realized by Matlab programming in the Windows environment. Main function include: automatic or manual marking of the respiratory signal; extraction and preservation of the relevant parameters. The rhyme style respiratory signal parameters have a significant distinctive feature by using this platform, but also proved the usefulness of this platform and the rationality of the respiratory signal parameters.
