Study of Speech Characteristics Based on Phase Space Reconstruction
Liang Chen · Zhongwen xinxi xuebao · 2002
Based on Takens theory,time delay method is used to reconstruct phase space of speech signal in this paper.In hyper dimensional phase space,similar sequence repeatability (RPT) of speech are calculated.At the same time,according to the RPT difference between voice and unvoice,speech phonemes are classified.The method proposed in this paper provides a new way for study of speech recognition.
