# 微调
|
||
|
||
## 安装训练环境
|
||
|
||
```
|
||
pip install git+https://github.com/modelscope/FunASR
|
||
```
|
||
|
||
## 数据准备
|
||
|
||
数据格式需要包括如下几个字段:
|
||
|
||
```
|
||
{"messages": [{"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "语音转写:<|startofspeech|>!https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/BAC009S0764W0121.wav<|endofspeech|>"}, {"role": "assistant", "content": "甚至出现交易几乎停滞的情况"}], "speech_length": 418, "text_length": 6}
|
||
{"messages": [{"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "语音转写:<|startofspeech|>!https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/BAC009S0916W0489.wav<|endofspeech|>"}, {"role": "assistant", "content": "湖北一公司以员工名义贷款数十员工负债千万"}], "speech_length": 572, "text_length": 11}
|
||
```
|
||
|
||
详细可以参考:`data/train_example.jsonl`
|
||
|
||
数据准备细节介绍:
|
||
|
||
- `messages[1]["content"]`: 音频文件的路径 + 语音识别的 prompt
|
||
- `messages[2]["content"]`: 音频文件标注文本
|
||
- `speech_length`: 音频文件的 fbank 帧数
|
||
- `text_length`: 音频文件标注文本的 token 数 (用 `Qwen3-0.6B` 编码)
|
||
|
||
`train_text.txt`
|
||
|
||
左边为数据唯一 ID,需与 `train_wav.scp` 中的 ID 一一对应 右边为音频文件标注文本,格式如下:
|
||
|
||
```
|
||
BAC009S0764W0121 甚至出现交易几乎停滞的情况
|
||
BAC009S0916W0489 湖北一公司以员工名义贷款数十员工负债千万
|
||
```
|
||
|
||
`train_wav.scp`
|
||
|
||
左边为数据唯一 ID,需与 `train_text.txt` 中的 ID 一一对应 右边为音频文件的路径,格式如下
|
||
|
||
```
|
||
BAC009S0764W0121 https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/BAC009S0764W0121.wav
|
||
BAC009S0916W0489 https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/BAC009S0916W0489.wav
|
||
```
|
||
|
||
`生成指令`
|
||
|
||
```
|
||
python tools/scp2jsonl.py \
|
||
--scp-file /path/to/train_wav.scp \
|
||
--transcript-file /path/to/train_text.txt \
|
||
--jsonl-file data/train_example.jsonl
|
||
```
|
||
|
||
## 启动训练
|
||
|
||
修改 `finetune.sh` 中的 `audio_encoder_conf.freeze`, `audio_adaptor_conf.freeze` 和 `llm_conf.freeze`。
|
||
|
||
将需要微调的模块 `freeze` 设置成 `false`(默认只微调 llm)。
|
||
|
||

|
||
|
||
```
|
||
bash finetune.sh
|
||
```
