Abstract

The embodiment of the invention provides a voice recognition method and device. The method includes the steps that a first acoustic model is obtained, the first acoustic model represents the mapping relation of input voice signals and a preset state, and the preset state is a basic element of text corresponding to the voice signals; the first voice signal is received; the probability value of the preset state is determined according to the first voice signal and a second acoustic model; the second acoustic model is determined according to a second input voice signal and the first acoustic model, and the first voice signal and the second voice signal are input by the same user; the voice signals include the first voice signal and the second voice signal; the probability value of the preset state corresponding to the first voice signal is decoded as first text according to a preset voice model and a dictionary. By means of the voice recognition method and device, recognition precision of voice input by specific users can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to a voice recognition method and device. Background technique [0002] Speech recognition technology is an information technology in which a machine converts human voices, bytes or phrases into corresponding words or symbols through the process of recognition and understanding, or gives a response. With the rapid development of information technology, speech recognition technology has been widely used in people's daily life. For example: when using a terminal device, the user can conveniently input information in the terminal device by using voice recognition technology. [0003] There are many kinds of speech recognition methods used in the existing speech recognition technology, for example: model matching method, probability model method and so on. At present, the industry usually adopts the probabilistic model method speech recognition tech...
