Embodiment

[0023] Such as figure 1 As shown, the embodiment of the present invention provides a kind of voice tracking and positioning method based on time-frequency domain, including voice collection module, voice storage module, voice pre-recognition module, voice processing module and voice tracking and positioning module, and the specific implementation steps are:

[0024] Step S1, the voice collection module collects the sound source signal, ensuring that the sampling frequency is 6-9 times the highest frequency of the signal, and ensuring the adequacy of the number of sampling bits. The sampling frequency refers to how many sound samples the computer samples per second, is Describe the sound quality, audio, sound card, and sound file quality standards of sound files. The higher the sampling frequency, that is, the shorter the sampling time interval, the more sound sample data the computer gets in a unit of time, regardless of the sampling frequency. The theory Generally speaking, t...

Abstract

The invention provides a time-frequency domain-based voice tracking and positioning method and belongs to the technical field of voice tracking and positioning. According to the time-frequency domain-based voice tracking and positioning method of the invention, a voice acquisition module, a voice storage module, a voice pre-recognition module, a voice processing module and a voice tracking and positioning module are adopted; the voice acquisition module is used for acquiring sound source signals; after the voice acquisition module finishes sampling, the voice acquisition module transmits datato the voice storage module; and the voice storage module is used for storing audios in the storage unit, and meanwhile, the voice storage module is used for analyzing the sampling precision of the received audios and converting the audios into adaptive formats. According to the voice tracking and positioning method, noises in the audios are separated, and therefore, audio tracking and positioningefficiency is improved; audio tracking and positioning accuracy is correspondingly improved; and many unnecessary troubles are saved for voice tracking and positioning in the time and frequency domain.

Description

technical field [0001] The present invention relates to the technical field of voice tracking and positioning methods, in particular to a voice tracking and positioning method based on the time-frequency domain. Background technique [0002] The frequency domain refers to the analysis function from the perspective of the frequency of the function. The opposite of the frequency domain is the time domain. Simply put, if the signal is analyzed from the time domain, the time is on the abscissa and the amplitude is on the ordinate, while in the frequency domain analysis, then The frequency is the abscissa, and the amplitude is the ordinate. From the perspective of the frequency domain, music is a vibration that changes with frequency. If we observe it from the perspective of the time domain, you will find that the music is still. [0003] In the voice tracking and positioning in the time-frequency domain, the audio is often mixed with other sounds, which we can call noise, and th...
