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.

It is recommended to use paddlepaddle 2.2.2 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/application.yaml . Among them, engine_list indicates the speech engine that will be included in the service to be started, in the format of <speech task>_<engine type>. At present, the speech tasks integrated by the service include: asr (speech recognition), tts (text to sppech) and cls (audio classification). Currently the engine type supports two forms: python and inference (Paddle Inference) Note: If the service can be started normally in the container, but the client access IP is unreachable, you can try to replace the host address in the configuration file with the local IP address.

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

    Output:

    [2022-02-23 11:17:32] [INFO] [server.py:64] Started server process [6384]
INFO:     Waiting for application startup.

4. ASR Client Usage

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

  • Command Line (Recommended)

    If 127.0.0.1 is not accessible, you need to use the actual service IP address.

7.2 Get the score between speaker audio embedding

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

  • Command Line (Recommended)

    If 127.0.0.1 is not accessible, you need to use the actual service IP address.

    paddlespeech_client vector --task score  --server_ip 127.0.0.1 --port 8090 --enroll 85236145389.wav --test 123456789.wav

    Usage:

    paddlespeech_client vector --help

    Arguments:

    • server_ip: server ip. Default: 127.0.0.1
    • port: server port. Default: 8090
    • input(required): Input text to generate.
    • task: the task of vector, can be use 'spk' or 'score。If get the score, this must be 'score' parameter.
    • enroll: enroll audio
    • test: test audio
