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.

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.yamlconf/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:

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

3. Server Usage

  • Command Line (Recommended)

    # in PaddleSpeech/demos/streaming_asr_server start the service
     paddlespeech_server start --config_file ./conf/ws_conformer_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

Note: The response time will be slightly longer when using the client for the first time

  • Command Line (Recommended)

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

    Usage:

    paddlespeech_client asr_online --help
    

    Arguments:

    • server_ip: server ip. Default: 127.0.0.1
    • port: server port. Default: 8090
    • input(required): Audio file to be recognized.
    • sample_rate: Audio ampling rate, default: 16000.
    • lang: Language. Default: "zh_cn".
    • audio_format: Audio format. Default: "wav".
    • punc.server_ip: punctuation server ip. Default: None.
    • punc.server_port: punctuation server port. Default: None.
