# chinese_speech_pretrain
### 简介
我们使用 WenetSpeech [1] train_l 集的 1 万小时中文数据作为无监督预训练数据。数据主要来源于 YouTube 和 Podcast，覆盖了各种类型录制场景、背景噪声、说话方式等，其领域主要包括有声书、解说、纪录片、电视剧、访谈、新闻、朗读、演讲、综艺和其他等10大场景。我们基于 Fairseq 工具包 [2] 分别训练了 wav2vec 2.0 [3] 和 HuBERT [4] 模型，遵循 [3,4] 中模型配置，每个预训练模型模型包括 BASE 和 LARGE 两种大小。对于 BASE 模型，我们使用 8 张 A100 显卡，梯度累计为 8，模拟 64 张显卡进行训练。对于 LARGE 模型，我们使用 16 张 A100 显卡，梯度累计为 8，模拟 128 张显卡进行训练。
### 模型下载
为了方便下载，在huggingface模型库里有fairseq模型，如[chinese-wav2vec2-base](https://huggingface.co/TencentGameMate/chinese-wav2vec2-base) 里的chinese-wav2vec2-base-fairseq-ckpt.pt
(We also provide fairseq checkpoint in huggingface model link, e.g chinese-wav2vec2-base-fairseq-ckpt.pt in [chinese-wav2vec2-base](https://huggingface.co/TencentGameMate/chinese-wav2vec2-base) )

## 下游任务：中文语音识别
为了验证预训练模型在下游 ASR 任务的效果，我们遵循 ESPnet [5,6,7] 工具包中的 Conformer [8] 模型实验配置，即将预训练模型作为特征提取器，对于输入语音提取预训练模型各隐层表征进行加权求和，得到的语音表征将替换传统 FBank 特征作为 Conformer ASR 模型的输入。
### Aishell 数据集 实验结果
我们使用 Aishell 178 小时训练集作为有监督数据进行训练，分别对比了使用 FBank 特征、wav2vec 2.0 BASE/LARGE 模型特征和 HuBERT BASE/LARGE 模型特征的字错误率 (Character Error Rate, CER) 结果。同时，我们额外对比了使用 WenetSpeech train_l 集 1 万小时中文数据进行训练时，其在 Aishell 测试集上的效果。训练数据使用了变速（0.9、1.0、1.1 倍）和 SpecAugment 数据增广技术，解码方式为 beam search，使用了基于 Transformer 的语言模型进行 rescoring。具体实验结果见下表：
| 输入特征 | 训练数据 | Dev | Test |
| ----------------- | -------- | --- | ---- |
| FBank [6] | 178h | 4.4 | 4.7 |
| FBank [1] | 1wh | / | 3.9 |
| Wav2vec 2.0 BASE | 178h | 4.2 | 4.7 |
| Wav2vec 2.0 LARGE | 178h | 3.8 | 4.1 |
| HuBERT Base | 178h | 4.1 | 4.3 |
| HuBERT LARGE | 178h | 3.1 | 3.3 |
### WenetSpeech 实验结果
我们使用 WenetSpeech train_s 100h 数据集作为有监督数据进行训练，分别对比了使用 FBank 特征、wav2vec 2.0 模型特征和 HuBERT 模型特征的字错误率 (Character Error Rate, CER) 结果。同时，额外对比了使用 train_m 集 1000h 和 train_l 集 1wh 中文数据 FBank 特征训练的模型结果。训练数据没有使用变速或 SpecAugment 数据增广技术，解码方式为 beam search，没有使用语言模型 rescoring。具体实验结果见下表：
| 输入特征 | 训练数据 | Dev 集 | Test_Net 集 | Test_Meeting 集 |
| ----------------- | -------- | ------ | ----------- | --------------- |
| FBank | 100h | 17.4 | 22.6 | 32.7 |
| FBank | 1000h | 11.6 | 14.6 | 22.4 |
| FBank | 1wh | 9.7 | 8.9 | 15.9 |
| wav2vec 2.0 BASE | 100h | 13.1 | 16.1 | 25.5 |
| wav2vec 2.0 LARGE | 100h | 11.7 | 13.8 | 25.5 |
| HuBERT BASE | 100h | 12.6 | 14.7 | 21.3 |
| HuBERT LARGE | 100h | 10.0 | 10.2 | 14.5 |
