Abstract

The invention provides an electronic device and a voice recognition method. The method comprises the following steps: receiving voice data, and generating a corresponding voiceprint feature vector according to the voice data; loading a voiceprint feature clustering model from a voiceprint feature clustering model database; inserting a plurality of nodes of the voiceprint feature clustering model into a candidate node sequence to form a plurality of candidate nodes, and identifying a target candidate node closest to the voiceprint feature vector in the plurality of candidate nodes; searching atarget candidate voiceprint feature vector sample matched with the voiceprint feature vector in all candidate voiceprint feature vector samples in the target candidate node; and identifying a target user and target user information corresponding to the target candidate voiceprint feature vector sample. Therefore, the user information corresponding to the voice data can be accurately and efficiently searched, so that the voice data recognition capability of the electronic device is improved.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an electronic device for recognizing a received voice, and a voice recognition method used by the electronic device. Background technique [0002] A voiceprint refers to a spectral graph showing sound wave characteristics drawn by a special electroacoustic conversion instrument (such as a spectrometer, a speech graph, etc.), and is a collection of various acoustic feature maps. For the human body, the voiceprint is a long-term stable characteristic signal. Due to the innate physiological differences of the vocal organs and the acquired behavioral differences, the voiceprint corresponding to each person's voice has a strong personal color. The voiceprint data collected through informatization is called voiceprint information. [0003] Therefore, the voice recognition operation is to extract the speaker's voice feature / speech content information (also called voice information), ...
