Govpr--golang implementation of the GMM-UBM algorithm for speaker recognition (voice recognition) engine

This is a creation in Article, where the information may have evolved or changed.

Brief introduction

GOVPR is a Golang implementation based on the GMM-UBM speaker recognition engine (voice recognition), which can be used for speech authentication and identification scenarios.
Currently only support Chinese digital voice, speech format is WAV format (bitrate 16000,16bits, mono)

Installation

Go get GITHUB.COM/LIUXP0827/GOVPR

Example

The following is a simple example. Can jump to example
For a detailed example, the voice in the example is a 8-digit number. A score is obtained after voice verification, and a threshold value can be set to determine if the voice is a registered trainer.
