Abstract

The invention provides an audio recognition method and device and an acoustic model training method and device, and relates to the technical field of audio processing. The audio recognition method comprises the steps of obtaining to-be-recognized audio data input by a user; extracting audio features in the to-be-recognized audio data; inputting the audio features into a pre-trained acoustic modelto obtain an audio recognition result corresponding to the to-be-recognized audio data, wherein the acoustic model is obtained through training by taking syllable information as a modeling unit, and the syllable information comprises initial consonants and final consonants of single characters. According to the application, the acoustic model used in the audio recognition process is obtained by training the syllable information as the modeling unit, the resource space occupation amount of the acoustic model is small, the resource space of the mobile terminal can be saved, the audio recognitionspeed of the mobile terminal is accelerated, and rapid voice recognition on the mobile terminal is realized.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular, to an audio recognition method and device, and an acoustic model training method and device. Background technique [0002] With the development of the Internet, the application of speech recognition technology is becoming more and more extensive. Speech recognition technology, also known as Automatic Speech Recognition (ASR), aims to convert the lexical content of speech into computer-readable input. For example, in the field of shared travel, it is possible to identify the recordings in the itinerary to confirm whether there is a safety accident during the ride-hailing process. [0003] At present, most of the speech recognition process is implemented on the cloud. Transferring the speech recognition process to the mobile terminal can greatly reduce the number of servers in the cloud. Among them, the acoustic models used for speech recognition on the cloud are...
