本项目是一个语音情感识别项目,目前效果一般,供大家学习使用。后面会持续优化,提高准确率,如果同学们有好的建议,也欢迎来探讨。
源码地址:SpeechEmotionRecognition-Pytorch
模型 | Params(M) | 预处理方法 | 数据集 | 类别数量 | 准确率 |
---|---|---|---|---|---|
BidirectionalLSTM | 1.8 | Flank | RAVDESS | 8 | 0.78 |
说明:
Audio_Speech_Actors_01-24.zip
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 mser -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/SpeechEmotionRecognition-Pytorch.git
cd SpeechEmotionRecognition-Pytorch/
python setup.py install
生成数据列表,用于下一步的读取需要,项目默认提供一个数据集RAVDESS,这个数据集的介绍页面,这个数据包含中性、平静、快乐、悲伤、愤怒、恐惧、厌恶、惊讶八种情感,本项目只使用里面的Audio_Speech_Actors_01-24.zip
,数据集,说话的语句只有Kids are talking by the door
和Dogs are sitting by the door
,可以说这个训练集是非常简单的。下载这个数据集并解压到dataset
目录下。
然后执行create_data.py
里面的create_ravdess_list('dataset/Audio_Speech_Actors_01-24', 'dataset')
函数即可生成数据列表,同时也生成归一化文件,具体看代码。
python create_data.py
如果自定义数据集,可以按照下面格式,audio_path
为音频文件路径,用户需要提前把音频数据集存放在dataset/audio
目录下,每个文件夹存放一个类别的音频数据,每条音频数据长度在3秒左右,如 dataset/audio/angry/······
。audio
是数据列表存放的位置,生成的数据类别的格式为 音频路径\t音频对应的类别标签
,音频路径和标签用制表符 \t
分开。读者也可以根据自己存放数据的方式修改以下函数。
执行create_data.py
里面的get_data_list('dataset/audios', 'dataset')
函数即可生成数据列表,同时也生成归一化文件,具体看代码。
python create_data.py
生成的列表是长这样的,前面是音频的路径,后面是该音频对应的标签,从0开始,路径和标签之间用\t
隔开。
dataset/Audio_Speech_Actors_01-24/Actor_13/03-01-01-01-02-01-13.wav 0
dataset/Audio_Speech_Actors_01-24/Actor_01/03-01-02-01-01-01-01.wav 1
dataset/Audio_Speech_Actors_01-24/Actor_01/03-01-03-02-01-01-01.wav 2
注意: create_data.py
里面的create_standard('configs/bi_lstm.yml')
函数必须要执行的,这个是生成归一化的文件。
接着就可以开始训练模型了,创建 train.py
。配置文件里面的参数一般不需要修改,但是这几个是需要根据自己实际的数据集进行调整的,首先最重要的就是分类大小dataset_conf.num_class
,这个每个数据集的分类大小可能不一样,根据自己的实际情况设定。然后是dataset_conf.batch_size
,如果是显存不够的话,可以减小这个参数。
# 单卡训练

# 多卡训练

每轮训练结束可以执行评估,评估会出来输出准确率,还保存了混合矩阵图片,保存路径output/images/
,如下。
在训练结束之后,我们得到了一个模型参数文件,我们使用这个模型预测音频。
