FreeSR (A Free Library for Speaker Recognition)，免费的声纹识别/性别识别SDK，支持Android/Windows/Linux等平台。

https://github.com/NonDay/FreeSR

1.实现算法：

gmm-ubm/i-vector/x-vector

2.功能

说话人识别(验证)，包括注册/识别两个阶段 (gmm-ubm/i-vector)

性别识别，根据语音片段判断性别(gmm-ubm/x-vector)

3.支持平台

Windows/ Linux/ Android

4.使用方法

4.1Windows

4.2 Android

通过Android Studio 加载.so库，在项目里新建libs文件夹，根据debug/release选择对应的so库，拷贝目录 arm64-v8a、armeabi-v7a、x86、x86_64到libs文件夹下

在build.gradle文件里添加

android {

......

sourceSets{

main{

jniLibs.srcDirs = ['libs']

}

}

}

新建Package(com.freesr)，将以下文件拷贝到该package目录

可进行说话人性别识别以及说话人识别，支持gmm-ubm和ivector，更详细的方法可参考java文件：

import com.freesr.*;

static {

System.loadLibrary("freesr");

}

//1. gener recognition

int sample_rate = 8000;

SpeakerRecognizerGMM SpkRec = new SpeakerRecognizerGMM(sample_rate);

ArrayListStr spk_models = new ArrayListStr();

ArrayListStr spk_names = new ArrayListStr();

spk_names.add("female");

spk_models.add("female.model");

spk_names.add("male");

spk_models.add("male.model");

boolean init = SpkRec.Init("freesr-gender-model.bin", spk_names, spk_models);

if(!init)

{

// failed to init

return ;

}

String rec_result = SpkRec.RecognizeSpeaker("english.wav");

double score = SpkRec.GetScore()

//2. speaker recognition

int sample_rate = 8000;

// SpeakerRecognizerIVector SpkRec = new SpeakerRecognizerIVector(sample_rate)

// boolean init = SpkRec.Init("freesr-ivector-model.bin", spk_names, spk_models);

SpeakerRecognizerGMM SpkRec = new SpeakerRecognizerGMM(sample_rate);

boolean init = SpkRec.Init("freesr-ubm-model.bin", spk_names, spk_models);

if(!init)

{

// failed to init

return ;

}

ArrayListStr fpaths = new ArrayListStr();

fpaths.add("english.wav");

fpaths.add("english.wav");

......

String reg_name = "spkA";

String reg_path = "spkA.model"

boolean ret = SpkRec.RegisterSpeaker(fpaths,reg_name,reg_path)

String rec_result = SpkRec.RecognizeSpeaker("english.wav");

double score = SpkRec.GetScore()
