# FunASR离线文件转写服务开发指南([点击此处](../docs/SDK_advanced_guide_offline_zh.md))
|
||||||
|
|
||||||
# 采用websocket协议的c++部署方案
|
|
||||||
|
|
||||||
## 快速上手
|
|
||||||
### 启动docker镜像
|
|
||||||
|
|
||||||
通过下述命令拉取并启动FunASR runtime-SDK的docker镜像:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
sudo docker pull registry.cn-hangzhou.aliyuncs.com/funasr_repo/funasr:funasr-runtime-sdk-cpu-0.1.0
|
|
||||||
|
|
||||||
sudo docker run -p 10095:10095 -it --privileged=true -v /root:/workspace/models registry.cn-hangzhou.aliyuncs.com/funasr_repo/funasr:funasr-runtime-sdk-cpu-0.1.0
|
|
||||||
```
|
|
||||||
如果您没有安装docker,可参考[Docker安装](https://alibaba-damo-academy.github.io/FunASR/en/installation/docker.html)
|
|
||||||
|
|
||||||
### 服务端启动
|
|
||||||
|
|
||||||
docker启动之后,启动 funasr-wss-server服务程序:
|
|
||||||
```shell
|
|
||||||
cd FunASR/funasr/runtime
|
|
||||||
./run_server.sh \
|
|
||||||
--download-model-dir /workspace/models \
|
|
||||||
--vad-dir damo/speech_fsmn_vad_zh-cn-16k-common-onnx \
|
|
||||||
--model-dir damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-onnx \
|
|
||||||
--punc-dir damo/punc_ct-transformer_zh-cn-common-vocab272727-onnx
|
|
||||||
```
|
|
||||||
服务端详细参数介绍可参考[服务端参数介绍](#命令参数介绍)
|
|
||||||
|
|
||||||
### 客户端测试与使用
|
|
||||||
|
|
||||||
下载客户端测试工具目录samples
|
|
||||||
```shell
|
|
||||||
wget https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/sample/funasr_samples.tar.gz
|
|
||||||
```
|
|
||||||
我们以Python语言客户端为例,进行说明,支持多种音频格式输入(.wav, .pcm, .mp3等),也支持视频输入(.mp4等),以及多文件列表wav.scp输入,其他版本客户端请参考文档([点击此处](#客户端用法详解))
|
|
||||||
```shell
|
|
||||||
python3 wss_client_asr.py --host "127.0.0.1" --port 10095 --mode offline --audio_in "../audio/asr_example.wav"
|
|
||||||
```
|
|
||||||
|
|
||||||
------------------
|
|
||||||
|
|
||||||
## 操作步骤详解
|
|
||||||
|
|
||||||
### 依赖库下载
|
|
||||||
|
|
||||||
Docker中已经预安装了依赖三方库,如果不用docker,请手动下载并安装([三方库下载与安装](requirements_install.md))
|
|
||||||
|
|
||||||
|
|
||||||
### 编译
|
|
||||||
|
|
||||||
```shell
|
|
||||||
git clone https://github.com/alibaba-damo-academy/FunASR.git && cd FunASR/funasr/runtime/websocket
|
|
||||||
mkdir build && cd build
|
|
||||||
cmake -DCMAKE_BUILD_TYPE=release .. -DONNXRUNTIME_DIR=/path/to/onnxruntime-linux-x64-1.14.0 -DFFMPEG_DIR=/path/to/ffmpeg-N-111383-g20b8688092-linux64-gpl-shared
|
|
||||||
make
|
|
||||||
```
|
|
||||||
|
|
||||||
### 启动服务部署
|
|
||||||
|
|
||||||
#### 命令参数介绍:
|
|
||||||
```text
|
|
||||||
--download-model-dir 模型下载地址,通过设置model ID从Modelscope下载模型。如果从本地模型启动,可以不设置。
|
|
||||||
--model-dir modelscope 中 ASR model ID,或者本地模型绝对路径
|
|
||||||
--quantize True为量化ASR模型,False为非量化ASR模型,默认是True
|
|
||||||
--vad-dir modelscope 中 VAD model ID,或者本地模型绝对路径
|
|
||||||
--vad-quant True为量化VAD模型,False为非量化VAD模型,默认是True
|
|
||||||
--punc-dir modelscope 中 标点 model ID,或者本地模型绝对路径
|
|
||||||
--punc-quant True为量化PUNC模型,False为非量化PUNC模型,默认是True
|
|
||||||
--port 服务端监听的端口号,默认为 10095
|
|
||||||
--decoder-thread-num 服务端启动的推理线程数,默认为 8
|
|
||||||
--io-thread-num 服务端启动的IO线程数,默认为 1
|
|
||||||
--certfile ssl的证书文件,默认为:../../../ssl_key/server.crt
|
|
||||||
--keyfile ssl的密钥文件,默认为:../../../ssl_key/server.key
|
|
||||||
```
|
|
||||||
|
|
||||||
#### 从modelscope中模型启动示例
|
|
||||||
```shell
|
|
||||||
./funasr-wss-server \
|
|
||||||
--download-model-dir /workspace/models \
|
|
||||||
--model-dir damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-onnx \
|
|
||||||
--vad-dir damo/speech_fsmn_vad_zh-cn-16k-common-onnx \
|
|
||||||
--punc-dir damo/punc_ct-transformer_zh-cn-common-vocab272727-onnx
|
|
||||||
```
|
|
||||||
|
|
||||||
注意:上面示例中,`model-dir`,`vad-dir`,`punc-dir`为模型在modelscope中模型名字,直接从modelscope下载模型并且导出量化后的onnx。如果需要从本地启动,需要改成本地绝对路径。
|
|
||||||
|
|
||||||
#### 从本地模型启动示例
|
|
||||||
|
|
||||||
##### 导出模型
|
|
||||||
|
|
||||||
```shell
|
|
||||||
python -m funasr.export.export_model \
|
|
||||||
--export-dir ./export \
|
|
||||||
--type onnx \
|
|
||||||
--quantize True \
|
|
||||||
--model-name damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch \
|
|
||||||
--model-name damo/speech_fsmn_vad_zh-cn-16k-common-pytorch \
|
|
||||||
--model-name damo/punc_ct-transformer_zh-cn-common-vocab272727-pytorch
|
|
||||||
```
|
|
||||||
导出过程详细介绍([点击此处](https://github.com/alibaba-damo-academy/FunASR/tree/main/funasr/export))
|
|
||||||
|
|
||||||
##### 启动服务
|
|
||||||
```shell
|
|
||||||
./funasr-wss-server \
|
|
||||||
--download-model-dir /workspace/models \
|
|
||||||
--model-dir ./exportdamo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-onnx \
|
|
||||||
--vad-dir ./exportdamo/speech_fsmn_vad_zh-cn-16k-common-onnx \
|
|
||||||
--punc-dir ./export/damo/punc_ct-transformer_zh-cn-common-vocab272727-onnx
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
### 客户端用法详解
|
|
||||||
|
|
||||||
下载客户端测试工具目录samples
|
|
||||||
```shell
|
|
||||||
wget https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/sample/funasr_samples.tar.gz
|
|
||||||
```
|
|
||||||
|
|
||||||
在服务器上完成FunASR服务部署以后,可以通过如下的步骤来测试和使用离线文件转写服务。
|
|
||||||
目前分别支持以下几种编程语言客户端
|
|
||||||
|
|
||||||
- [Python](#python-client)
|
|
||||||
- [CPP](#cpp-client)
|
|
||||||
- [html网页版本](#Html网页版)
|
|
||||||
- [Java](#Java-client)
|
|
||||||
|
|
||||||
#### python-client
|
|
||||||
若想直接运行client进行测试,可参考如下简易说明,以python版本为例:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
python3 wss_client_asr.py --host "127.0.0.1" --port 10095 --mode offline --audio_in "../audio/asr_example.wav" --output_dir "./results"
|
|
||||||
```
|
|
||||||
|
|
||||||
命令参数说明:
|
|
||||||
```text
|
|
||||||
--host 为FunASR runtime-SDK服务部署机器ip,默认为本机ip(127.0.0.1),如果client与服务不在同一台服务器,需要改为部署机器ip
|
|
||||||
--port 10095 部署端口号
|
|
||||||
--mode offline表示离线文件转写
|
|
||||||
--audio_in 需要进行转写的音频文件,支持文件路径,文件列表wav.scp
|
|
||||||
--output_dir 识别结果保存路径
|
|
||||||
```
|
|
||||||
|
|
||||||
### cpp-client
|
|
||||||
进入samples/cpp目录后,可以用cpp进行测试,指令如下:
|
|
||||||
```shell
|
|
||||||
./funasr-wss-client --server-ip 127.0.0.1 --port 10095 --wav-path ../audio/asr_example.wav
|
|
||||||
```
|
|
||||||
|
|
||||||
命令参数说明:
|
|
||||||
|
|
||||||
```text
|
|
||||||
--server-ip 为FunASR runtime-SDK服务部署机器ip,默认为本机ip(127.0.0.1),如果client与服务不在同一台服务器,需要改为部署机器ip
|
|
||||||
--port 10095 部署端口号
|
|
||||||
--wav-path 需要进行转写的音频文件,支持文件路径
|
|
||||||
```
|
|
||||||
|
|
||||||
### Html网页版
|
|
||||||
|
|
||||||
在浏览器中打开 html/static/index.html,即可出现如下页面,支持麦克风输入与文件上传,直接进行体验
|
|
||||||
|
|
||||||
<img src="images/html.png" width="900"/>
|
|
||||||
|
|
||||||
### Java-client
|
|
||||||
|
|
||||||
```shell
|
|
||||||
FunasrWsClient --host localhost --port 10095 --audio_in ./asr_example.wav --mode offline
|
|
||||||
```
|
|
||||||
