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.

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.

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:

wget -c https://paddlespeech.bj.bcebos.com/PaddleAudio/zh.wav https://paddlespeech.bj.bcebos.com/PaddleAudio/en.wav

3. Server Usage

  • Command Line (Recommended)

    # start the service
    paddlespeech_server start --config_file ./conf/application.yaml
    

    Usage:

    paddlespeech_server start --help
    

    Arguments:

    • config_file: yaml file of the app, defalut: ./conf/application.yaml
    • log_file: log file. Default: ./log/paddlespeech.log

4. ASR Client Usage

  • Command Line (Recommended)

    paddlespeech_client asr --server_ip 127.0.0.1 --port 8090 --input ./zh.wav
    

    Usage:

    paddlespeech_client asr --help
    

    Arguments:

    • server_ip: server ip. Default: 127.0.0.1
    • port: server port. Default: 8090
