本项目使用了EcapaTdnn、ResNetSE、ERes2Net、CAM++等多种先进的声纹识别模型,不排除以后会支持更多模型,同时本项目也支持了MelSpectrogram、Spectrogram、MFCC、Fbank等多种数据预处理方法,使用了ArcFace Loss,ArcFace loss:Additive Angular Margin Loss(加性角度间隔损失函数),对应项目中的AAMLoss,对特征向量和权重归一化,对θ加上角度间隔m,角度间隔比余弦间隔在对角度的影响更加直接,除此之外,还支持AMLoss、ARMLoss、CELoss等多种损失函数。

说明:
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.6 -c pytorch -c nvidia
使用pip安装,命令如下:
python -m pip install mvector -U -i https://pypi.tuna.tsinghua.edu.cn/simple
建议源码安装,源码安装能保证使用最新代码。
git clone https://github.com/yeyupiaoling/VoiceprintRecognition-Pytorch.git
cd VoiceprintRecognition-Pytorch/
python setup.py install
本教程笔者使用的是CN-Celeb,这个数据集一共有约3000个人的语音数据,有65W+条语音数据,下载之后要解压数据集到dataset
目录,另外如果要评估,还需要下载CN-Celeb的测试集。如果读者有其他更好的数据集,可以混合在一起使用,但最好是要用python的工具模块aukit处理音频,降噪和去除静音。
首先是创建一个数据列表,数据列表的格式为<语音文件路径\t语音分类标签>
,创建这个列表主要是方便之后的读取,也是方便读取使用其他的语音数据集,语音分类标签是指说话人的唯一ID,不同的语音数据集,可以通过编写对应的生成数据列表的函数,把这些数据集都写在同一个数据列表中。
执行create_data.py
程序完成数据准备。
python create_data.py
执行上面的程序之后,会生成以下的数据格式,如果要自定义数据,参考如下数据列表,前面是音频的相对路径,后面的是该音频对应的说话人的标签,就跟分类一样。自定义数据集的注意,测试数据列表的ID可以不用跟训练的ID一样,也就是说测试的数据的说话人可以不用出现在训练集,只要保证测试数据列表中同一个人相同的ID即可。

配置文件中默认使用的是Fbank预处理方法,如果要使用其他预处理方法,可以修改配置文件中的安装下面方式修改,具体的值可以根据自己情况修改。如果不清楚如何设置参数,可以直接删除该部分,直接使用默认值。
# 数据预处理参数
preprocess_conf:
# 音频预处理方法,支持:MelSpectrogram、Spectrogram、MFCC、Fbank
feature_method: 'Fbank'
# 设置API参数,更参数查看对应API,不清楚的可以直接删除该部分,直接使用默认值
method_args:
sample_frequency: 16000
num_mel_bins: 80
使用train.py
训练模型,本项目支持多个音频预处理方式,通过configs/ecapa_tdnn.yml
配置文件的参数preprocess_conf.feature_method
可以指定,MelSpectrogram
为梅尔频谱,Spectrogram
为语谱图,MFCC
梅尔频谱倒谱系数等等。通过参数augment_conf_path
可以指定数据增强方式。训练过程中,会使用VisualDL保存训练日志,通过启动VisualDL可以随时查看训练结果,启动命令visualdl --logdir=log --host 0.0.0.0
# 单卡训练
CUDA_VISIBLE_DEVICES=0 python train.py
# 多卡训练
CUDA_VISIBLE_DEVICES=0,1 torchrun --standalone --nnodes=1 --nproc_per_node=2 train.py

函数,在编写模型的时候,模型是有两个输出的,第一个是模型的分类输出,第二个是音频特征输出。所以在这里要输出的是音频的特征值,有了音频的特征值就可以做声纹识别了。我们输入两个语音,通过预测函数获取他们的特征数据,使用这个特征数据可以求他们的对角余弦值,得到的结果可以作为他们相识度。对于这个相识度的阈值threshold
,读者可以根据自己项目的准确度要求进行修改。

audio/a_1.wav 和 audio/b_2.wav 不是同一个人,相似度为:-0.09565544128417969
在上面的声纹对比的基础上,我们创建infer_recognition.py
实现声纹识别。同样是使用上面声纹对比的infer()
预测函数,通过这两个同样获取语音的特征数据。 不同的是笔者增加了load_audio_db()
和register()
,以及recognition()
,第一个函数是加载声纹库中的语音数据,这些音频就是相当于已经注册的用户,他们注册的语音数据会存放在这里,如果有用户需要通过声纹登录,就需要拿到用户的语音和语音库中的语音进行声纹对比,如果对比成功,那就相当于登录成功并且获取用户注册时的信息数据。第二个函数register()
其实就是把录音保存在声纹库中,同时获取该音频的特征添加到待对比的数据特征中。最后recognition()
函数中,这个函数就是将输入的语音和语音库中的语音一一对比。
有了上面的声纹识别的函数,读者可以根据自己项目的需求完成声纹识别的方式,例如笔者下面提供的是通过录音来完成声纹识别。首先必须要加载语音库中的语音,语音库文件夹为audio_db
,然后用户回车后录音3秒钟,然后程序会自动录音,并使用录音到的音频进行声纹识别,去匹配语音库中的语音,获取用户的信息。通过这样方式,读者也可以修改成通过服务请求的方式完成声纹识别,例如提供一个API供APP调用,用户在APP上通过声纹登录时,把录音到的语音发送到后端完成声纹识别,再把结果返回给APP,前提是用户已经使用语音注册,并成功把语音数据存放在audio_db
文件夹中。
