# FunASR离线文件转写服务一键部署教程

FunASR提供可一键本地或者云端服务器部署的离线文件转写服务，内核为FunASR已开源runtime-SDK。集成了达摩院语音实验室在Modelscope社区开源的语音端点检测(VAD)、Paraformer-large语音识别(ASR)、标点恢复(PUNC) 等相关能力，可以准确、高效的对音频进行高并发转写。

## 环境安装与启动服务

环境准备与配置（[点击此处](../../docs/runtime/aliyun_server_tutorial.md)）
### 获得脚本工具并一键部署

通过以下命令运行一键部署服务，按照提示逐步完成FunASR runtime-SDK服务的部署和运行。目前暂时仅支持Linux环境，其他环境参考文档[高阶开发指南]()。
受限于网络，funasr-runtime-deploy.sh一键部署工具的下载可能不顺利，遇到数秒还未下载进入一键部署工具的情况，请Ctrl + C 终止后再次运行以下命令。

```shell
curl -O https://raw.githubusercontent.com/alibaba-damo-academy/FunASR-APP/main/TransAudio/funasr-runtime-deploy.sh ; sudo bash funasr-runtime-deploy.sh install
```

#### 启动过程配置详解

```

##### 输入宿主机中FunASR服务可执行程序路径

输入FunASR服务可执行程序的宿主机路径，Docker运行时将自动挂载到Docker中运行。默认不输入的情况下将指定Docker中默认的/workspace/FunASR/funasr/runtime/websocket/build/bin/funasr-wss-server。

```text
[3/10]
  Please enter the path to the excutor of the FunASR service on the localhost.
  If not set, the default /workspace/FunASR/funasr/runtime/websocket/build/bin/funasr-wss-server in Docker is used.
  Setting the path to the excutor of the FunASR service on the localhost:
  Corresponding, the path of FunASR in Docker is /workspace/FunASR/funasr/runtime/websocket/build/bin/funasr-wss-server
```

##### 设置宿主机提供给FunASR的端口
设置提供给Docker的宿主机端口，默认为10095。请保证此端口可用。
```text
[4/10]
  Please input the opened port in the host used for FunASR server.
  Default: 10095
  Setting the opened host port [1-65535]:
  The port of the host is 10095
```

##### 设置Docker中提供给FunASR的端口
设置Docker中FunASR服务使用的端口，默认为10095，此端口将于step1.4中设置的宿主机端口进行映射。
```text
5/10]
  Please input port for docker mapped.
  Default: 10095, the opened port of current host is 10095
  Setting the port in Docker for FunASR server [1-65535]:
  The port in Docker for FunASR server is 10095
```

##### 设置FunASR服务的推理线程数
设置FunASR服务的推理线程数，默认为宿主机核数，同时自动设置服务的IO线程数，为推理线程数的四分之一。
```text
[6/10]
  Please input thread number for FunASR decoder.
  Default: 1
  Setting the number of decoder thread:

  The number of decoder threads is 1
  The number of IO threads is 1
```

##### 所有设置参数展示及确认

##### 检查Docker服务

检查当前宿主机是否安装了Docker服务，若未安装，则安装Docker并启动。

```text

```

##### 启动FunASR Docker

启动FunASR Docker，等待step1.2选择的模型下载完成并启动FunASR服务。

```text

  The service has been started.
  If you want to see an example of how to use the client, you can run sudo bash funasr-runtime-deploy.sh -c .
```

#### 启动已经部署过的FunASR服务
一键部署后若出现重启电脑等关闭Docker的动作，可通过如下命令直接启动FunASR服务，启动配置为上次一键部署的设置。

```shell
sudo bash funasr-runtime-deploy.sh start
```

#### 关闭FunASR服务

```shell
sudo bash funasr-runtime-deploy.sh stop
```

#### 重启FunASR服务

根据上次一键部署的设置重启启动FunASR服务。
```shell
sudo bash funasr-runtime-deploy.sh restart
```

#### 替换模型并重启FunASR服务

替换正在使用的模型，并重新启动FunASR服务。模型需为ModelScope中的ASR/VAD/PUNC模型。

```shell
sudo bash scripts/funasr-runtime-deploy.sh update model <model ID in ModelScope>

e.g
sudo bash scripts/funasr-runtime-deploy.sh update model damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-onnx
```

### 测试与使用离线文件转写服务

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Python、C++、Java版本client的的命令行运行，以及可在浏览器可直接体验的html网页版本，更多语言client支持参考文档【FunASR高阶开发指南】。
funasr-runtime-deploy.sh运行结束后，可通过命令以交互的形式自动下载测试样例samples到当前目录的funasr_samples中，并设置参数运行：

```shell
sudo bash funasr-runtime-deploy.sh client
```

可选择提供的Python和Linux C++范例程序，以Python范例为例：

```text
Will download sample tools for the client to show how speech recognition works.
  Please select the client you want to run.
    1) Python
    2) Linux_Cpp
  Enter your choice: 1

  Please enter the IP of server, default(127.0.0.1): 
  Please enter the port of server, default(10095): 
  Please enter the audio path, default(/root/funasr_samples/audio/asr_example.wav): 

  Run pip3 install click>=8.0.4
Looking in indexes: http://mirrors.cloud.aliyuncs.com/pypi/simple/
Requirement already satisfied: click>=8.0.4 in /usr/local/lib/python3.8/dist-packages (8.1.3)

  Run pip3 install -r /root/funasr_samples/python/requirements_client.txt
Looking in indexes: http://mirrors.cloud.aliyuncs.com/pypi/simple/
Requirement already satisfied: websockets in /usr/local/lib/python3.8/dist-packages (from -r /root/funasr_samples/python/requirements_client.txt (line 1)) (11.0.3)

  Run python3 /root/funasr_samples/python/wss_client_asr.py --host 127.0.0.1 --port 10095 --mode offline --audio_in /root/funasr_samples/audio/asr_example.wav --send_without_sleep --output_dir ./funasr_samples/python

  ...
  ...

  pid0_0: 欢迎大家来体验达摩院推出的语音识别模型。
Exception: sent 1000 (OK); then received 1000 (OK)
end

  If failed, you can try (python3 /root/funasr_samples/python/wss_client_asr.py --host 127.0.0.1 --port 10095 --mode offline --audio_in /root/funasr_samples/audio/asr_example.wav --send_without_sleep --output_dir ./funasr_samples/python) in your Shell.

```

#### 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" --send_without_sleep --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

```shell
export LD_LIBRARY_PATH=/root/funasr_samples/cpp/libs:$LD_LIBRARY_PATH
/root/funasr_samples/cpp/funasr-wss-client --server-ip 127.0.0.1 --port 10095 --wav-path /root/funasr_samples/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
```
