Problems solved by technology

Moreover, the speech recognition method using the genetic algorithm to train the continuous hidden Markov model has become the mainstream technology of speech recognition. This method has a faster recognition speed and a higher recognition rate in speech recognition, but most of the computer speech recognition methods are limited. For voice passwords, voice feature recognition is still insufficient

Embodiment Construction

[0008] In order to overcome the existing computer voice recognition methods mostly limited to voice codes, and voice feature recognition is still insufficient, the present invention provides a computer voice recognition method, which realizes the accuracy of a computer voice recognition method process sex.

[0009] From an intuitive point of view, a person's voice contains the characteristics of this person, which is the so-called individuality of voice, just as a person has a specific reference, and a person also has a specific "voiceprint". In an isolated word recognition device, it is not good to recognize people. But here I specifically hope that the computer will recognize people. The principle of speaker recognition is basically the same as that of pattern matching recognition. The key is to find speech parameters that can reflect personal characteristics, such as vocal cord waveform, vocal tract configuration, nasal formant, intonation, etc.

[0010] Its main steps i...

Abstract

Aiming at overcoming the situation that most of the current computer speech recognition methods are limited to speech cipher and the speech feature recognition is still poor, the invention provides a computer speech recognition method and fulfills the accuracy of the method process of computer speech recognition.

Description

technical field [0001] The patent of the present invention relates to a method of computer speech recognition, especially to realize the accuracy of the process of a computer speech recognition method. Background technique [0002] At present, it is generally known that the fields involved in speech recognition technology include: signal processing, pattern recognition, probability theory and information theory, vocalization mechanism and auditory mechanism, artificial intelligence and so on. In recent years, in the field of biometric technology, voiceprint recognition technology has attracted worldwide attention due to its unique advantages of convenience, economy and accuracy, and has increasingly become an important and popular security verification method in people's daily life and work. Moreover, the speech recognition method using the genetic algorithm to train the continuous hidden Markov model has become the mainstream technology of speech recognition. This method ha...
