Abstract

The invention disclose an updating method, a device, and a system of a voice recognition device, which relate to voice recognition technology, and are invented for improving voice recognition rate. The method comprises the following steps: receiving voice input signals; utilizing a local voice recognition device to conduct voice recognition for the voice input signals, so as to obtain a local voice recognition result; acquiring an optimal recognition result as a final voice recognition result from the local voice recognition result and a cloud voice recognition result, wherein the cloud voice recognition result is obtained in a way that when the local voice device conducts voice recognition for the voice input signals, and meanwhile a cloud voice recognition device is utilized to conduct voice recognition for the voice input signals; combining acquired user feedback information, and the final voice recognition result to define whether the reliability of the local voice recognition result satisfies requirements; utilizing the cloud voice recognition device to conduct updating for the local voice recognition device when the reliability of the local voice recognition result is sure not to satisfy the requirements.

Description

technical field [0001] The invention relates to speech recognition technology, in particular to a method, device and system for updating speech recognition equipment. Background technique [0002] Speech recognition technology is a technology that enables machines to convert speech signals into corresponding text or commands through the process of recognition and understanding. Among them, the speech recognition engine usually includes an acoustic model and a language model, wherein the acoustic model is responsible for completing the conversion from speech to phonemes (such as phonetic symbols in English and the consonants of Pinyin in Chinese), and the language model is responsible for completing the conversion from phonemes to text. Both the model and the language model cooperate to complete the speech-to-text recognition process. [0003] There are three kinds of speech recognition technologies in the prior art: the first is speech recognition technology based on cloud ...
