Embodiment Construction

[0040]A method for mixing and outputting background sound and text speech in a speech synthesis system, including the user providing synthetic text information to the synthesis system, and the synthesis system undergoes text analysis (sentence and word segmentation processing on the text) and prosody analysis (produces aloud speech) volume, pitch, intonation, etc.), and then call the pronunciation unit in the sound bank to be combined into continuous synthetic text speech data, which is characterized in that the background sound bank is set up, and the background sound index corresponding to the serial number or name is set up with the content of the sound bank, In the resource management center of the speech synthesis system, add program content such as adding, deleting, volume adjustment, and description content editing management operations on the background sound library; add the CSSML mark of the background sound in the position where the background sound needs to be added ...

Abstract

In this method, a customer supplies the synthetic information to the synthesis system. It includes the synthetic text information. The synthesis system, by analyzing the text and the rules of the rhyming, combines the synthetic text with audio data. The invention constructs the background audio library, and adds the CSSML mark of the background sound to the synthetic context to strengthen the audio effect.

Description

technical field [0001] The invention relates to a speech synthesis method, in particular to a method for managing and applying background music in the conversion process from text to natural speech by using a computer. Background technique [0002] At present, in IVR, call center and other telephone voice systems, the speech synthesis system that completes the function from text to voice has been widely used. With the widening range of information provided by the information service system, the increasing amount of information, and the increasingly stringent timeliness requirements, the previous manual services have been unable to meet this demand, and the function of the speech synthesis system is to combine massive information Text is converted into voice files in real time and played immediately. The synthesized voice is clear and accurate, which can meet the needs of real-time information broadcasting, reduce the cost of manual services and avoid many problems such as s...
