Speech corpus generating device and method, speech synthesizing system and method

Abstract

The invention provides a speech corpus generating device and method. The speech corpus generating device comprises a speech extracting device, a speech identifying device and a text marking device, wherein the speech extracting device is used for extracting speech data of a preset pronouncing person from collected data; the speech identifying device is used for identifying the speech data of the preset pronouncing person as a text; and the text marking device is used for marking the text. The invention also provides a speech synthesizing system and method. According to the speech corpus generating device and method provided by the invention, the speech corpus is generated by automatically collecting the data and automatically processing the data, so that a large amount of labor cost is saved. Besides, a construction period of the speech synthesizing system is shortened, the speech synthesizing system is conveniently updated and the personalized customization is realized.

Description

technical field [0001] The present invention relates to the technical field of speech synthesis, more specifically, to a speech library generation device and method thereof, and a speech synthesis system and method thereof, which realize the automatic collection of predetermined speech data and the synthesis of specific speakers voice. Background technique [0002] It has become an urgent need for the application and development of information technology to realize humanized and intelligent effective interaction between man and machine, and to build an efficient and natural human-machine communication environment. As a very practical and important technology in speech technology, speech synthesis technology, or text-to-speech technology TTS (Text-To-Speech), converts text information into natural speech signals and realizes real-time conversion of any text. It endows the computer with the ability to speak freely like a human, changes the traditional cumbersome operation of ...

AI Technical Summary

Problems solved by technology

It can be seen that the construction of the sound library in the traditional speech synthesis system mainly relies on manual operation, and professional recording personnel need to be arranged to manually mark the rhythm and segments. The construction requires a large workload and a long production cycle, so the size of the sound library is often restricted

On the other hand, because the recording and labeling of the sound bank has high technical requirements, the speech synthesis system can only provide a limited number of specific speakers' timbres, and it is difficult to respond to diverse application requirements.

In short, building a traditional sound bank requires a lot of manpower and workload, and it is difficult to adapt to the problem of customization and personalization in the Internet age
