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.
