Voice processing method and device based on artificial intelligence

Abstract

The invention proposes a voice processing method and device based on artificial intelligence, and the method comprises the steps: voice for segmentation, forming a plurality of voice segments, recognizing each voice segment, obtaining a recognition text segment of each voice segment, determining an original text segment of a current recognition text segment from an original text corresponding to the current recognition text segment according to the sequence of recognition text segments, splicing the original text segment and the voice segments corresponding to an original text segment, obtaining a sentence text and sentence voice corresponding to the sentence text, generating the pinyin of the sentence text, forming a phone sequence according to the pinyin, enabling the phone sequence andthe sentence voice to be aligned, obtaining a phone boundary, and forming target data for the training of the voice synthesis model through the sentence text, sentence voice, pinyin and phone boundary. Therefore, the method achieves the automatic segmentation and marking of the voice, and forms the marking data which is higher in accuracy and is used for training the voice synthesis model.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to an artificial intelligence-based speech processing method and device thereof. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that responds in a manner similar to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural language processing and expert systems, etc. [0003] At present, in the field of speech synthesis, most of the speech segmentation is performed manually, and then the original text corresponding to each speech segment is man...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a speech processing method based on artificial intelligence, to realize automatic segmentation and labeling of speech, and to form labeling data with high accuracy for training the speech synthesis model , which is used to solve the problems of low efficiency of labeling data generation in the existing manual labeling method, prone to errors in the process of segmentation or recognition, and high labor costs
