- Command line
```

```
Output
```
[2022-05-02 18:12:29,767] [ INFO] - The punc text: 我认为跑步最重要的就是给我带来了身体健康。
[2022-05-02 18:12:29,767] [ INFO] - Response time 0.096548 s.
```
- Python3 API
```python
from paddlespeech.server.bin.paddlespeech_client import TextClientExecutor
textclient_executor = TextClientExecutor()
res = textclient_executor(
input="我认为跑步最重要的就是给我带来了身体健康",
server_ip="127.0.0.1",
port=8190,)
print(res)
```
Output:
``` bash
我认为跑步最重要的就是给我带来了身体健康。
```
## Join streaming asr and punctuation server
By default, each server is deployed on the 'CPU' device and speech recognition and punctuation prediction can be deployed on different 'GPU' by modifying the' device 'parameter in the service configuration file respectively.
We use `streaming_ asr_server.py` and `punc_server.py` two services to lanuch streaming speech recognition and punctuation prediction services respectively. And the `websocket_client.py` script can be used to call streaming speech recognition and punctuation prediction services at the same time.
### 1. Start two server
``` bash
Note: streaming speech recognition and punctuation prediction are configured on different graphics cards through configuration files
bash server.sh
```
### 2. Call client
- Command line
```
paddlespeech_client asr_online --server_ip 127.0.0.1 --port 8290 --punc.server_ip 127.0.0.1 --punc.port 8190 --input ./zh.wav
```

## 标点预测
### 1. 服务端使用方法
- 命令行
**注意:** 默认部署在 `cpu` 设备上，可以通过修改服务配置文件中 `device` 参数部署在 `gpu` 上。
``` bash
在 PaddleSpeech/demos/streaming_asr_server 目录下启动标点预测服务
paddlespeech_server start --config_file conf/punc_application.yaml
```
使用方法：
```bash
paddlespeech_server start --help
```
参数：
- `config_file`: 服务的配置文件。
- `log_file`: log 文件。
输出：
``` bash

### 2. 标点预测客户端使用方法
**注意：** 初次使用客户端时响应时间会略长
- 命令行 (推荐使用)
```
paddlespeech_client text --server_ip 127.0.0.1 --port 8190 --input "我认为跑步最重要的就是给我带来了身体健康"
```
输出
```
[2022-05-02 18:12:29,767] [ INFO] - The punc text: 我认为跑步最重要的就是给我带来了身体健康。
[2022-05-02 18:12:29,767] [ INFO] - Response time 0.096548 s.
```
- Python3 API
```python
from paddlespeech.server.bin.paddlespeech_client import TextClientExecutor
textclient_executor = TextClientExecutor()
res = textclient_executor(
input="我认为跑步最重要的就是给我带来了身体健康",
server_ip="127.0.0.1",
port=8190,)
print(res)
```
输出：
``` bash
我认为跑步最重要的就是给我带来了身体健康。
```
## 联合流式语音识别和标点预测
**注意:** 默认部署在 `cpu` 设备上，可以通过修改服务配置文件中 `device` 参数将语音识别和标点预测部署在不同的 `gpu` 上。
使用 `streaming_asr_server.py` 和 `punc_server.py` 两个服务，分别启动流式语音识别和标点预测服务。调用 `websocket_client.py` 脚本可以同时调用流式语音识别和标点预测服务。
### 1. 启动服务
``` bash
注意：流式语音识别和标点预测通过配置文件配置到不同的显卡上
bash server.sh
```
### 2. 调用服务
- 使用命令行：
```
paddlespeech_client asr_online --server_ip 127.0.0.1 --port 8290 --punc.server_ip 127.0.0.1 --punc.port 8190 --input ./zh.wav
```
输出：
