使用准备

• Anaconda 3
• Python 3.8
• PaddlePaddle 2.4.0
• Windows 10 or Ubuntu 18.04

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==2.4.0 cudatoolkit=10.2 --channel https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/

• 安装ppser库。

使用pip安装，命令如下：

python -m pip install ppser -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-PaddlePaddle.git
cd SpeechEmotionRecognition-PaddlePaddle/
python setup.py install

准备数据

生成数据列表，用于下一步的读取需要，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秒以上，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/angry/104817-4-0-2.wav	4
dataset/audio/fear/105029-7-2-5.wav	3
dataset/audio/happy/107228-5-0-0.wav	5

训练

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
CUDA_VISIBLE_DEVICES=0 python train.py
# 多卡训练
python -m paddle.distributed.launch --gpus '0,1' train.py

评估

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。

预测

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。

python infer.py --audio_path=dataset/test.wav
