Example Embodiment

[0028] The specific content of the present invention will be described below in conjunction with the accompanying drawings.

[0029] The system of the present invention is divided into two modes: training mode and conversion mode. The training mode can be used to build a specific person's speech feature library; the conversion mode can convert the voice of speaker A into the voice of specific person B.

[0030] The system described in the present invention has five parts in all:

[0031] Recording module: used to receive the speaker's voice, and send the recording to the recognition module for feature extraction and semantic recognition.

[0032] Speech recognition module: Receive the recording of the recording module, in the training mode, extract the feature information of the recording and send it to the synthesis module for building the feature library; in the conversion mode, perform semantic recognition on the voice, and output the recognized text.

Abstract

The invention discloses a voice conversion system and a voice conversion method. The voice conversion system comprises a recording module, a voice recognition module, a voice synthesis module, a loud-speaking module and a user control module, wherein the recording module is connected with the voice recognition module so as to receive speaking voice of a speaker and record a voice frequency; the voice recognition module performs voice recognition according to the difference of the modes, extracts relevant voice feature information in a training mode and converts the voice signal into relevant character information in a conversion mode; the voice synthesis module receives and stores the voice feature information transmitted by the voice recognition model in the training mode, and synthesizing the received text information and the voice feature information of a special person in the conversion mode, and transmitting the synthesized voice to the loud-speaking module; a user can control a module control system to be started and closed, select a working mode and select an appointer to be synthesized, i.e. convert the sound into the voice of anyone.

Description

technical field [0001] The invention relates to the technical fields of voice recognition technology and personalized voice synthesis, which can convert the words spoken by a speaker A into the voice of a specific person B and then play them. Background technique [0002] Speech recognition technology is a technology that converts the speaker's voice into text. Personalized speech synthesis technology is developed on the basis of speech synthesis technology TTS. In addition to the traditional TTS conversion of text into speech broadcast, it can also be synthesized into a speech with specific person characteristics, but it needs to obtain the designated person first. Speech audio, extract the speech features of specific people from the audio, and build a personalized speech feature library. Such as the patent "Accepting the text input by the user on the mobile phone or the webpage and synthesizing it into a personalized voice method" (public number: CN103065620A) proposed by...
