# Speech Server
|
||||
|
||||
## Introduction
|
||||
This demo is an implementation of starting the voice 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.
|
||||
|
||||
|
||||
## Usage
|
||||
### 1. Installation
|
||||
see [installation](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md).
|
||||
|
||||
You can choose one way from easy, meduim and hard to install paddlespeech.
|
||||
|
||||
### 2. Prepare config File
|
||||
The configuration file contains the service-related configuration files and the model configuration related to the voice tasks contained in the service. They are all under the `conf` folder.
|
||||
|
||||
### 3. Server Usage
|
||||
- Command Line (Recommended)
|
||||
|
||||
```bash
|
||||
# start the service
|
||||
paddlespeech_server start --config_file ./conf/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:
|
||||
```bash
|
||||

|
||||
config_file="./conf/application.yaml",
|
||||
log_file="./log/paddlespeech.log")
|
||||
```
