基于PaddlePaddle实现的声纹识别系统

前言

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。

安装环境

  • 首先安装的是PaddlePaddle的GPU版本,如果已经安装过了,请跳过。
conda install paddlepaddle-gpu==2.4.1 cudatoolkit=10.2 --channel https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/
  • 安装ppvector库。

使用pip安装,命令如下:

python -m pip install ppvector -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_PaddlePaddle.git
cd VoiceprintRecognition_PaddlePaddle/
python setup.py install

修改预处理方法

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:LogMelSpectrogram、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:
    sr: 16000
    n_mels: 80

训练模型

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。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
python -m paddle.distributed.launch --gpus '0,1' train.py

评估模型

训练结束之后会保存预测模型,我们用预测模型来预测测试集中的音频特征,然后使用音频特征进行两两对比,计算EER和MinDCF。

python eval.py

输出类似如下:

声纹对比

下面开始实现声纹对比,创建infer_contrast.py程序,编写infer()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。

python infer_contrast.py --audio_path1=audio/a_1.wav --audio_path2=audio/b_2.wav

输出类似如下:

声纹识别

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()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。
