[0045] For ease of understanding, see figure 1 , a rhythm-based speech synthesis method provided by the invention comprises the following steps:

[0046] S1. Divide the text to be processed into paragraphs to obtain a plurality of natural paragraphs.

[0047] S2. Perform word segmentation processing on each natural paragraph to obtain the word segmentation result of each natural paragraph, perform part-of-speech tagging on the word segmentation result of each natural paragraph, perform weighted calculation on the part-of-speech tagging result of the natural paragraph, and determine the corresponding natural paragraph according to the calculation result. The sentiment type of the paragraph.

[0048] S3. Perform word segmentation on the full text of the text to be processed, obtain a word segmentation result of the full text, perform part-of-speech tagging on the word segmentation result of the full text, perform weighted calculation on the part-of-speech tagging result of the ...

Abstract

The invention relates to the technical field of speech recognition, and discloses a rhythm-based speech synthesis method and system, and the method comprises the steps: dividing a to-be-processed text into a plurality of natural paragraphs, carrying out the word segmentation processing and part-of-speech tagging of each natural paragraph and a full text, and carrying out the weighted calculation according to a part-of-speech tagging result, thereby obtaining a speech recognition result. Determining the emotion type of the corresponding natural paragraph and the emotion type of the full text according to the calculation result, determining the rhythm of the natural paragraph and the rhythm of the full text according to the emotion type, and carrying out weighted calculation according to preset voice attribute data, the rhythm of the full text and the rhythm of the natural paragraph to obtain the voice synthesis rhythm of each natural paragraph; the corresponding natural paragraph is subjected to voice conversion through the voice synthesis rhythm to obtain the voice synthesis result, so that the rhythm of the natural paragraph is determined by utilizing the emotion, the rhythm generation difficulty is reduced, and the voice synthesis result is more vivid.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a method and system for rhythm-based speech synthesis. Background technique [0002] In speech synthesis, the selection of the basic rhythm is the most important step. The selection of the basic rhythm is determined by the tone of the text. If it does not conform to the tone of the text, it will cause errors in the speech synthesis of all texts, resulting in funny scenes. [0003] In speech synthesis (TTS), the existing technology only performs simple text conversion and output on speech, but the rhythm generation of speech synthesis is difficult, resulting in very rigid speech synthesis results, difficulty in expressing real emotions, and reducing user interaction. experience. SUMMARY OF THE INVENTION [0004] The present invention provides a rhythm-based speech synthesis method and system, which solves the technical problem that the rhythm generation of sp...
