+# 背景
+
+TESS音频情绪分类任务。
+从而校验和测试 paddle.audio 的feature, backend等相关模块。
+
+本实验采用了PaddleSpeech提供了PANNs的CNN14的预训练模型进行finetune：
+- CNN14: 该模型主要包含12个卷积层和2个全连接层，模型参数的数量为 79.6M，embbedding维度是 2048。
+
+`PANNs`([PANNs: Large-Scale Pretrained Audio Neural Networks for Audio Pattern Recognition](https://arxiv.org/pdf/1912.10211.pdf))是基于Audioset数据集训练的声音分类/识别的模型。经过预训练后，模型可以用于提取音频的embbedding。本示例将使用`PANNs`的预训练模型Finetune完成声音分类的任务。
+
+## 数据集
+
+[TESS: Toronto emotional speech set](https://tspace.library.utoronto.ca/handle/1807/24487) 是一个包含有 200 个目标词的时长为 2 ~ 3 秒的音频,七种情绪的数据集。由两个女演员录制(24岁和64岁),其中情绪分别是愤怒,恶心,害怕,高兴,惊喜,伤心,平淡。
+
+## 模型指标
+
+根据 `TESS` 提供的fold信息，对数据集进行 5-fold 的 fine-tune 训练和评估，dev准确率如下：
+
+|Model|feat_type|Acc| note |
+|--|--|--| -- |
+|CNN14| mfcc | 0.9929 |3 epoch |
+|CNN14| logmelspectrogram | 0.9983 | 3 epoch |
+|CNN14| spectrogram| 0.95 | 11 epoch |
+|CNN14| melspectrogram| 0.9375 | 17 epoch |
+
