Problems solved by technology

Correspondingly, in the online decoding stage, the acoustic model, language model, and pronunciation dictionary need to be built into a large decoding resource. The memory occupied by the decoding resource is very large, ranging from several G to tens of G, and it is often necessary to load the decoding resource in advance. , takes a long time, and uses a very large decoding resource to identify the voice stream, and the recognition speed is slow

Abstract

Embodiments of the invention provide a speech flow processing method and device. The method comprises the steps of obtaining a to-be-identified speech flow for a target task, and determining a targetidentifier of the target task; searching a target decoding small resource matched with the target identifier from a decoding small resource group according to the target identifier; and processing theto-be-identified speech flow by utilizing the target decoding small resource under the condition that the target decoding small resource is found to obtain a processing result. By means of the method, the decoding speed can be improved, and the memory occupied by decoding resources is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of voice recognition, and in particular, to a voice stream processing method and device. Background technique [0002] In the era of artificial intelligence, voice, as one of the entrances of human-computer interaction, is used more and more widely. The process of voice interaction between people and mobile phones, computers or other smart devices is as follows: first, the device collects the voice spoken by the person, then the device converts the collected voice into text, then analyzes the text, and finally the device gives the corresponding instruction. In this interactive process, the technology of converting speech into text is called speech recognition; among them, Chinese speech recognition is to convert Chinese speech into Chinese text strings, and English speech recognition is to convert English speech into English word strings. [0003] In related technologies, speech...
