语音服务

介绍

这个 demo 是一个启动离线语音服务和访问服务的实现。它可以通过使用paddlespeech_server 和 paddlespeech_client的单个命令或 python 的几行代码来实现。

使用方法

1. 安装

请看 安装文档.

推荐使用 paddlepaddle 2.2.2 或以上版本。 你可以从 medium，hard 两种方式中选择一种方式安装 PaddleSpeech。

2. 准备配置文件

配置文件可参见 conf/application.yaml 。 其中，engine_list表示即将启动的服务将会包含的语音引擎，格式为 <语音任务>_<引擎类型>。 目前服务集成的语音任务有： asr(语音识别)、tts(语音合成)、cls(音频分类)、vector(声纹识别)以及text(文本处理)。 目前引擎类型支持两种形式：python 及 inference (Paddle Inference) 注意： 如果在容器里可正常启动服务，但客户端访问 ip 不可达，可尝试将配置文件中 host 地址换成本地 ip 地址。

ASR client 的输入是一个 WAV 文件（.wav），并且采样率必须与模型的采样率相同。

可以下载此 ASR client 的示例音频：

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

3. 服务端使用方法

  • 命令行 (推荐使用)

    # 启动服务
paddlespeech_server start --config_file ./conf/application.yaml

    使用方法：

    paddlespeech_server start --help

    参数:

    • config_file: 服务的配置文件，默认： ./conf/application.yaml
    • log_file: log 文件. 默认：./log/paddlespeech.log

    输出:

    [2022-02-23 11:17:32] [INFO] [server.py:64] Started server process [6384]
INFO:     Waiting for application startup.
[2022-02-23 11:17:32] [INFO] [on.py:26] Waiting for application startup.
INFO:     Application startup complete.
[2022-02-23 11:17:32] [INFO] [on.py:38] Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8090 (Press CTRL+C to quit)
[2022-02-23 11:17:32] [INFO] [server.py:204] Uvicorn running on http://0.0.0.0:8090 (Press CTRL+C to quit)

  • Python API

    from paddlespeech.server.bin.paddlespeech_server import ServerExecutor

server_executor = ServerExecutor()
server_executor(
    config_file="./conf/application.yaml", 
    log_file="./log/paddlespeech.log")

    输出：

    INFO:     Started server process [529]
[2022-02-23 14:57:56] [INFO] [server.py:64] Started server process [529]
INFO:     Waiting for application startup.

[2022-02-23 14:57:56] [INFO] [server.py:204] Uvicorn running on http://0.0.0.0:8090 (Press CTRL+C to quit)

4. ASR 客户端使用方法

注意： 初次使用客户端时响应时间会略长

  • 命令行 (推荐使用)

    若 127.0.0.1 不能访问，则需要使用实际服务 IP 地址

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

    使用帮助:

    paddlespeech_client asr --help

    • port: 服务端口，默认: 8090。
    • input(必须输入): 用于识别的音频文件。
    • sample_rate: 音频采样率，默认值：16000。
    • lang: 模型语言，默认值：zh_cn。
    • audio_format: 音频格式，默认值：wav。

    输出:

    [2022-02-23 18:11:22,819] [    INFO] - {'success': True, 'code': 200, 'message': {'description': 'success'}, 'result': {'transcription': '我认为跑步最重要的就是给我带来了身体健康'}}
[2022-02-23 18:11:22,820] [    INFO] - time cost 0.689145 s.

  • Python API

    from paddlespeech.server.bin.paddlespeech_client import ASRClientExecutor

    port=8090,
    sample_rate=16000,
    lang="zh_cn",
    audio_format="wav")

7.2 音频声纹打分

注意： 初次使用客户端时响应时间会略长

  • 命令行 (推荐使用)

    若 127.0.0.1 不能访问，则需要使用实际服务 IP 地址

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

    使用帮助:

    paddlespeech_client vector --help

    参数:

    • server_ip: 服务端ip地址，默认: 127.0.0.1。
    • port: 服务端口，默认: 8090。
    • input(必须输入): 用于识别的音频文件。
    • task: vector 的任务，可选spk或者score。默认是 spk。
    • enroll: 注册音频；。
    • test: 测试音频。
