Abstract

The invention discloses a speech recognition method and device. According to one embodiment, the method comprises the steps of conducting high-pass filtering treatment on speech signals by responding to the detection that a microphone receives the speech signals containing crosstalk signals; eliminating the crosstalk signals in the speech signals after high-pass filtering treatment; conducting automatic gain control treatment on the speech signals with the crosstalk signals removed, so as to obtain target speech signals; and extracting feature vectors from the target speech signals, and inputting a pre-trained acoustic model into the feature vectors, so as to obtain a speech recognition result matched with the target speech signals, wherein the acoustic model is used for representing the corresponding relation of the feature vectors and the speech recognition result. In this way, the success rate of speech recognition is improved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and especially to a voice recognition method and device. Background technique [0002] With the development of computer technology, voice recognition technology has been applied in more and more fields, such as smart home, industrial control, voice interaction system of terminal equipment, etc. The use of speech recognition technology can make information processing and acquisition more convenient, thereby improving the work efficiency of users. [0003] However, in the existing speech recognition methods, the speech signal to be recognized is usually input to the acoustic model trained based on the pure speech signal, and then the speech recognition result is obtained. Since the speech signal to be recognized is usually quite different from the pure speech signal, this speech recognition method has the problem of low recognition succ...
