Voiceless sound and voiced sound judging method and device and voice synthesizing system

Abstract

The embodiment of the invention provides a voiceless sound and voiced sound judging method and device and a voice synthesizing system. The method comprises the steps of setting a voiceless sound and voiced sound judging problem set, utilizing speech training data and the voiceless sound and voiced sound judging problem set to train a voiceless sound and voiced sound judging model of a dichotomia decision tree structure, receiving voice test data and utilizing the trained voiceless sound and voiced sound judging model to judge whether the voice test data are voiceless sound or voiced sound. In addition, non-leaf nodes in the dichotomia decision tree structure are problems in the voiceless sound and voiced sound judging problem set, and leaf nodes in the dichotomia decision tree structure are voiceless sound and voiced sound judging results. The embodiment of the voiceless sound and voiced sound judging method improves the voiceless sound and voiced sound judging success rate and the voice synthesizing quality.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of speech processing, and more specifically, relate to a method, device, and speech synthesis system for judging unvoiced and voiced sounds. Background technique [0002] In today's information age, various information devices have emerged as the times require: fixed telephones and mobile phones for voice transmission; servers and personal computers for information resource sharing and processing; various TV sets for video data display, etc. Wait. These devices are produced to solve actual needs in specific fields. With the advent of the integration of electronic consumption, computer, and communication (3C), people are paying more and more attention to the research on the comprehensive utilization of information equipment in various fields, so as to make full use of existing resources and equipment to serve people. better service. [0003] Speech synthesis is the technology of p...

AI Technical Summary

Problems solved by technology

[0005] However, the set of questions designed to train the Hidden Markov (HMM) model is not specifically for unvoiced judgment, and during the prediction process, the questions in the decision tree may not be related to unvoiced sound at all, but are used to judge speech voicing, which naturally leads to inaccurate determination of voicing

When the accuracy of unvoiced and voiced sound determination is not high enough and errors occur, the unvoiced voiced sound and unvoiced voiced sound of the synthesized speech will seriously affect the synthesis effect
