Problems solved by technology

However, with the development of global diversification, users are no longer satisfied with single-language recognition
[0003] Most of the existing speech recognition systems are monolingual speech recognition, even if there are multilingual speech recognition methods, taking Chinese and English as an example, due to the particularity of Chinese English pronunciation and different habits of each person, resulting in Recognition effect is low

Abstract

The embodiment of the invention discloses a plurilingual voice decoding diagram establishment method, a device, a server and a medium and relates to the technical field of voice recognition. The method comprises the following steps: marking main language words and secondary language words in a sample corpus bank with phonetic symbols so as to obtain pronunciation phonemes of the main language words and the secondary language words; according to sample voice associated with sample corpora in the sample corpus bank, confirming acoustic features of the main language words and the secondary language words; according to the main language words and the secondary language words in the sample corpora in the sample corpus bank, and the pronunciation phonemes and the acoustic features of the main language words and the secondary language words, confirming decoding diagrams of plurilingual recognition. According to the embodiment of the invention, the pronunciation phonemes of the main language words and the secondary language words are obtained according to the sample corpus bank, furthermore acoustic features associated with the main language words and the secondary language words are confirmed, the decoding diagrams of plurilingual recognition are finally obtained, and the requirement of voice recognition for plurilingual mixed reading crowds can be met.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of speech recognition, and in particular to a method, device, server and medium for constructing a multilingual speech decoding graph. Background technique [0002] Speech recognition is a high technology that allows machines to convert voice signals into corresponding text or commands through the process of recognition and understanding. For example, in a smart home, after waking up the smart device, the user only needs to speak the corresponding command to operate the device. After the device correctly recognizes the user's voice information, it will act according to the information intention. Speech recognition plays an important role in human-computer interaction, and has great development prospects in various fields of modern society. However, with the development of global diversification, users are no longer satisfied with single-language recognition. [0003] Most of the ...
