Abstract

The invention provides a dialect pronunciation labeling method, a language recognition method and a related device, wherein the dialect pronunciation labeling method comprises the steps: carrying outaudio-text alignment of an obtained dialect training set, and obtaining a word boundary of each word in the dialect training set; carrying out voice-phoneme decoding on the dialect training set by using a mandarin voice recognition model to obtain a pronunciation phoneme sequence of each voice in the dialect training set; determining a pronunciation phoneme sequence of each word in the dialect training set according to the decoded pronunciation phoneme sequence of each voice in the dialect training set and the word boundary of each word in the dialect training set; determining a target word with a plurality of pronunciations according to the pronunciation phoneme sequence of each word in the dialect training set; and adding the target pronunciation of the target word into a mandarin pronunciation dictionary to obtain a target pronunciation dictionary. According to the embodiment of the invention, dialect pronunciation annotation can be automatically completed without depending on manpower, and manpower and time cost can be saved.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a dialect pronunciation labeling method, a language recognition method and related devices. Background technique [0002] Language is one of the most direct and natural ways for human beings to realize information interaction. With different regions, people use different dialects. With the development of society and the popularization of artificial intelligence, the speech recognition of relevant dialects has great challenges. [0003] Among them, the pronunciation dictionary is the basis of speech recognition. Compared with Mandarin, some regional dialects will have accent changes in pronunciation, for example: Mandarin "干艺子<gàn sházǐ>" and Sichuan dialect "干恩子<gàn shǎzǐ>" , the pronunciation of the word "啦" has changed from 2 tones to 3 tones, and it is also possible that a phrase may appear consecutively and aphonically when pronounced in a dialect. For ...
