Abstract

The invention discloses a method of recognizing voice. The method comprises steps: a preset voice knowledge source is used to generate searching space containing preset information of a client and used for decoding voice signals; a to-be-recognized voice signal feature vector sequence is extracted; the possibility that the feature vector is corresponding to a searching space basic unit is calculated; and with the possibility as input, decoding operation is executed in the searching space to obtain a word sequence corresponding to the feature vector sequence. The invention also provides a device for recognizing voice, and another method and another device for recognizing voice. By adopting the method provided by the invention, as the preset information of the client is included while the searching space for decoding is generated, information related to the client can be accurately recognized while the voice signals acquired by the client are recognized, and thus, the voice recognition accuracy can be improved, and the use experience of the user is enhanced.

Description

technical field [0001] The present application relates to speech recognition technology, in particular to a speech recognition method and device. The present application also relates to another voice recognition method and device. Background technique [0002] Speech is the acoustic performance of language, the most natural, effective and convenient means for human to exchange information, and also a kind of support for human thinking. Automatic Speech Recognition (ASR) usually refers to the process of allowing computers and other devices to convert human spoken language into corresponding output text or commands through recognition and understanding of speech. Its core framework is: on the basis of statistical model modeling, according to the feature sequence O extracted from the speech signal to be recognized, the following Bayesian decision criterion is used to solve the optimal word sequence W corresponding to the speech signal to be recognized *: [0003] W*=argmaxP(...
