Research of the breathing characteristics when reading short song-poems

The paper select short Song-poems as typescripts, by the method of experimental phonetics, collect voice signal and respiration signal, explore its breathing rhythm characteristics. We have studied that respiration reset levels lies mainly in the amplitude of the breathing reset, respiration reset time cannot distinguish breathing levels effectively. Inspiratory amplitude and expiratory amplitude can be roughly divided into two levels, male tend to choose larger breathing reset, female mostly use smaller breathing reset. Besides, between inspiratory time and inspiratory amplitude, inspiratory amplitude and expiratory amplitude exist significant positive correlation, the change of one party will effect or predict the other party.
