# Speech Server
## Introduction
This demo is an implementation of starting the streaming speech service and accessing the service. It can be achieved with a single command using `paddlespeech_server` and `paddlespeech_client` or a few lines of code in python.
Streaming ASR server only support `websocket` protocol, and doesn't support `http` protocol.
## Usage
### 1. Installation
see [installation ](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md ).
It is recommended to use **paddlepaddle 2.2.1** or above.
You can choose one way from meduim and hard to install paddlespeech.
### 2. Prepare config File
The configuration file can be found in `conf/ws_application.yaml` 和 `conf/ws_conformer_application.yaml` .
At present, the speech tasks integrated by the model include: DeepSpeech2 and conformer.
The input of ASR client demo should be a WAV file(`.wav`), and the sample rate must be the same as the model.
Here are sample files for thisASR client demo that can be downloaded:
```bash
wget -c https://paddlespeech.bj.bcebos.com/PaddleAudio/zh.wav
```
### 3. Server Usage
- Command Line (Recommended)
```bash
# in PaddleSpeech/demos/streaming_asr_server start the service
paddlespeech_server start --config_file ./conf/ws_conformer_application.yaml
```
Usage:
```bash
paddlespeech_server start --help
```
Arguments:
- `config_file` : yaml file of the app, defalut: `./conf/application.yaml`
- `log_file` : log file. Default: `./log/paddlespeech.log`
Output:
