Voice information recognition method and terminal equipment

Abstract

The invention relates to the field of information recognition, in particular to a voice information recognition method and terminal equipment. The voice information recognition method and the terminal equipment resolve the problem in the prior art that when a sound source of voice information to be recognized is not stable or sound transmission equipment generates interference, determined feature information has deviation easily. Voiced sound information is extracted from the voice information to be recognized, fundamental tone frequency parameters and an MFCC are extracted from the voiced sound information, the fundamental tone frequency parameters are processed to obtain a fundamental tone frequency parameter matching value, the MFCC is processed to obtain an MFCC parameter matching value, and the feature information of the voice information to be recognized is determined according to the fundamental tone frequency parameter matching value and the MFCC parameter matching value. Due to the facts that voiced sound in the voice information has the periodicity of a voice fundamental tone, the voiced sound information has a relatively fixed frequency in general, the characteristic of the voiced sound information can be treated as a quasi-steady-state process, and the probability that the feature information of the voice information determined according to the voiced sound information has mistakes is low.

Description

technical field [0001] The invention relates to the field of information recognition, in particular to a voice information recognition method and terminal equipment. Background technique [0002] With the development of electronic technology, electronic equipment has been upgraded to have more and more functions. Among them, the voice control function has attracted much attention, and various voice assistant applications have emerged. Voice assistant applications enable users to use electronic equipment Read text messages, introduce restaurants, ask about the weather, recommend programs, etc. The key to realizing voice assistant applications is the speech recognition system. The speech signal not only contains the semantic information of the speaker, but also contains the characteristic information of the speaker. People can extract the speaker's gender and other identity information from the speech signals of different speakers. . [0003] The current speech information r...
