METHOD AND DEVICE FOR TEXT VOICE SYNTHESIS

摘要

PROBLEM TO BE SOLVED: To enable a vocoder type text voice synthesis system, which makes an HMM learn a spectrum parameter sequence and generates the spectrum parameter string from the HMM with a text to synthesize a voice, to output a synthesized voice of high quality and to make it easy to automatically build the system. SOLUTION: The parameter string of a high-precision excitation source model of a vocoder type voice encoding system is modeled through the learning of the hidden Markov model, the high-precision excitation source parameter sequence is generated from the hidden Markov model according to the text to control the high-precision excitation source, and the excitation signal generated by the high-precision excitation source is applied to a synthesizing filter to generate a voice waveform.
