Description

technical field

[0001] The invention belongs to the technical field of speech recognition, in particular to a fast method for speech recognition of Chinese phrases of a specific person. Background technique

[0002] The existing specific person speech recognition method and application system usually have the following deficiencies:

[0003] (1) Too many training times or too little recognizable vocabulary, making it inconvenient for users to use;

[0004] (2) It supports the recognition of short words (usually less than 4 syllables), but does not support the recognition of phrases (usually about 10 syllables), and its application fields are limited;

[0005] (3) The core algorithm adopts the Hidden Markov Model (HMM) or Dynamic Time Warping (DTW) method, which has high complexity, takes up a lot of system resources, and has a slow recognition speed.

[0006] Such as Philips, Samsung, and Siemens released in the first half of 2001 have voice dialing function mobile phones ...
