Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] A preferred embodiment of a method for constructing a voice library for news broadcast voice synthesis provided by the present invention includes:

[0034] S1. Obtain news corpus, screen the news corpus to obtain the target recording text;

[0035] 1) Obtain news corpus:

[0036] Usually when making a synthesized sound, we usually use the existing corpus, which can save a lot of time, but it also hides hidden dangers, because there are certain differences between the existing recorded text library and specific fields in terms of rhythm and emotion sex. When making synthetic audio for news broadcasts, for example: a text from financial news: "Shanghai Stock Exchan...

Abstract

The invention relates to a voice library construction method and system for news broadcasting voice synthesis. The method comprises the following steps: to obtain news voice materials, screening the news voice materials to obtain a target recording text, and pre-processing the target recording text, finally recording the target recording text and collecting target voice, and constructing a voice library. The voice library construction system for the news broadcasting voice synthesis comprises a voice material collecting and screening module, a pre-processing module, a voice collecting module and a voice library generating module. According to the provided voice library construction method and system for the news broadcasting voice synthesis, the quality is high, and the time efficiency is high.

Description

technical field [0001] The invention relates to the field of data statistics, in particular to a method and system for constructing a speech library for news broadcast speech synthesis. Background technique [0002] In recent years, with the maturity of speech technology, speech synthesis technology is gradually being applied to speech signal processing systems such as speech interaction, sound broadcast, and personalized sound production. In the field of society and business, synthetic sound, as a display of sound, brings convenience and richness to social life, and has potential broad use value. The quality of synthetic sound system is mainly considered by the following two aspects: synthesis technology programs and sound banks. [0003] The quality of the sound library can be considered in many aspects, such as timbre, text, rhythm, naturalness, cost performance and time. Generally, the first thing is to choose a specific and suitable timbre and voice actor according to...
