Abstract

The invention discloses a Henan dialect speech recognition system, comprising a speech acquisition device, a speech recognition device and a speech determining device, wherein the speech acquisition device receives Henan dialect speech instructions input by an user; the speech recognition device comprises a speech extraction unit and a characteristics compression unit; the speech extraction unit extracts short-time audio characteristics of the Henan dialect according to speech instructions received; audio frame characteristics with similarity meeting preset conditions are found in the speech instructions by the the characteristics compression unit according to the extracted zero-crossing rate, fundamental frequency and Mel frequency cepstrum coefficient characteristics; the speech determining device comprises a speech determining part and a speech output part; one or more optimized candidate recognition characteristics are selected from the audio characteristics by the speech determining part via a Hidden Markov Model ( HMM ) and are output to the speech output part; by adopting the above solution, operation efficiency and recognition effect are increased in the speech recognition system, and thus the system has a good market application value.

Description

technical field [0001] The invention relates to the field of voice recognition, in particular to a Henan dialect voice recognition system. Background technique [0002] Voice is the most common way of human-to-human interaction, and it is also one of the most direct and effective ways. In modern society, the emergence and popularization of computers have changed the living conditions of human beings, and people are becoming more and more accustomed to using computers to complete various daily tasks. We hope that communicating with machines is as convenient as communicating with humans. Computers can not only "hear" human voices, but also "understand" the meaning of voices. The human-computer interaction method that allows computers to understand speech is speech recognition. [0003] Our country has a vast territory and a large population, and each region has its own dialect. There are great differences in tone and pronunciation between dialects and Mandarin, and between ...
