Abstract

The invention discloses a Matlab-based spectrogram generation and display method and device. The method comprises the steps of preprocessing a collected voice signal; performing matlab parameter configuration on the preprocessed voice signal to generate a two-dimensional spectrogram; performing coordinate point information extraction on the two-dimensional spectrogram; and performing Matlab dynamic modeling according to the coordinate point information to generate and display a three-dimensional spectrogram. According to the Matlab-based spectrogram generation and display method, after the voice signal is preprocessed, the two-dimensional spectrogram is generated by utilizing Matlab, and then the coordinate point information of the two-dimensional spectrogram is extracted for dynamic modeling to obtain the three-dimensional spectrogram, so that the voiceprint characteristics of the voice signal can be visually and accurately reflected, the accuracy and efficiency of voice identification are improved, and the technical problem of generating the spectrogram which accurately reflects the voiceprint characteristics to improve the accuracy and efficiency of voiceprint identification issolved.

Description

technical field [0001] The present application relates to the technical field of speech processing, in particular to a Matlab-based spectrogram generation and display method and related devices. Background technique [0002] The conventional voiceprint identity test method for the same speaker is to display the voice as a spectrogram, display the voiceprint characteristics on the graph, and then compare the voiceprint features between the generated spectrogram and the preset spectrogram. Yes, thereby authenticating. Therefore, how to generate a spectrogram that accurately reflects the characteristics of the voiceprint to improve the accuracy and efficiency of voiceprint identification is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The application provides a Matlab-based spectrogram generation and display method and related devices, which are used to solve the technical problem of generating a spectrogram that a...
