ASR应用

介绍

ASR应用是参考开源项目https://github.com/k2-fsa/sherpa-onnx实现的语音转文本应用,通过onnx运行时运行推理模型获取输出,最后在屏幕显示结果。

源项目不支持开发者手机OH4.1版本,所以本项目基于原项目做了部分改造,目前能在开发者手机一代OH4.1,开发者手机二代的OH4.1和OH5.0版本运行。

使用说明

  1. 首先打开应用,等待模型初始化。
  2. 页面默认停留在麦克风识别页,点击Start,开始实时语音识别
  3. 点击Stop停止语音识别
  4. 再点击Save recorded audio,可以选择文件保存路径,文件名以.wav结尾。
  5. 点击下方From file,切换到从文件识别页,点击Select .wav file (16kHz),
  6. 选择需要进行语音识别的wav格式音频文件,点击右上角的确认
  7. 会返回页面并进行推理
  8. 等待推理完成,

具体实现

  1. 应用启动与初始化

    • 用户启动应用后,主线程调用 aboutToAppear 方法,创建工作线程实例并发送 init-streaming-asr 消息请求初始化 ASR 模型。
    • 同时,主线程调用 initMic 方法初始化麦克风,会检查并请求麦克风权限,若权限获取成功则创建音频捕获器并监听 readData 事件。
    • 工作线程接收到 init-streaming-asr 消息后,调用 initStreamingAsr 方法初始化识别器,完成后向主线程发送 init-streaming-asr-done 消息,主线程更新按钮状态和提示信息。
  2. 从文件进行语音识别

    • 用户点击 “Select .wav file (16kHz)” 按钮,主线程通过文件选择器让用户选择文件。
    • 主线程将文件信息通过 streaming-asr-decode-file 消息发送给工作线程。
    • 工作线程接收到消息后调用 decodeFile 方法进行文件解码,完成后将结果通过 streaming-asr-decode-file-done 消息发送给主线程,主线程更新识别结果和提示信息。
  3. 从麦克风进行语音识别

    • 用户点击 “Start” 按钮,主线程向工作线程发送 streaming-asr-decode-mic-start 消息,同时启动音频捕获器。
    • 音频捕获器触发 readData 事件,主线程调用 micCallback 方法处理音频数据,并将数据通过 streaming-asr-decode-mic-samples 消息发送给工作线程。
    • 工作线程接收并处理音频数据,将识别结果通过 streaming-asr-decode-mic-result 消息发送给主线程,主线程更新识别结果。
    • 用户点击 “Stop” 按钮,主线程向工作线程发送 streaming-asr-decode-mic-stop 消息,停止音频捕获器,并启用保存按钮。
  4. 保存录制音频

    • 用户点击 “Save recorded audio” 按钮,主线程通过文件选择器让用户选择保存路径,然后将录制的音频数据保存为 WAV 文件。
