This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including cordova-plugin-bdasr with all npm packages installed. Try it out:

cordova-plugin-bdasr lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("cordova-plugin-bdasr/[??]")

百度语音识别cordova插件(更新至bdasr_V3_20190515_c9eed5d.jar)

  • 这是一个百度语音识别的cordova插件。为什么使用百度语音识别,因为是免费的,识别的准确度也还挺不错的。
  • 这个插件只包含语音识别功能,不包含其他的比如唤醒、长语音功能。
  • 百度语音开发文档 http://ai.baidu.com/docs#/ASR-API/top

支持平台

  1. Android(bdasr_V3_20190515_c9eed5d.jar)
  2. iOS

安装

在线npm安装

本地安装

github文件超过100M之后只能使用LFS才能上传,但是同时也有带宽限制。为了避免各种限制,所以只能辛苦各位自行下载libBaiduSpeech.a,并放到插件的src/ios/BDSClientLib目录中。

  • 第一步,将插件下载到本地
  • 第二步,下载iOS SDK中缺少的libBaiduSpeech.a
  • 第三步,添加libBaiduSpeech.a到src/ios/BDSClientLib
  • 第四步,安装插件
cordova plugin add /your localpath --variable APIKEY=your apikey --variable SECRETKEY=your secretkey --variable APPID=your appid

在线npm安装(推荐)

在线npm安装不受任何限制,可直接安装。

cordova plugin add cordova-plugin-bdasr --variable APIKEY=your apikey --variable SECRETKEY=your secretkey --variable APPID=your appid

API使用

开启语音识别

startSpeechRecognize

代码示例

cordova.plugins.bdasr.startSpeechRecognize();

关闭语音识别

closeSpeechRecognize

代码示例

cordova.plugins.bdasr.closeSpeechRecognize();

取消语音识别

cancelSpeechRecognize

代码示例

cordova.plugins.bdasr.cancelSpeechRecognize();

事件监听

addEventListener

代码示例

// 语音识别事件监听
cordova.plugins.bdasr.addEventListener(function (res) {
  // res参数都带有一个type
  if (!res) {
    return;
  }

  switch (res.type) {
    case "asrReady": {
      // 识别工作开始,开始采集及处理数据
      $scope.$apply(function () {
        // TODO
      });
      break;
    }

    case "asrBegin": {
      // 检测到用户开始说话
      $scope.$apply(function () {
        // TODO
      });
      break;
    }

    case "asrEnd": {
      // 本地声音采集结束,等待识别结果返回并结束录音
      $scope.$apply(function () {
      // TODO
      });
      break;
    }

    case "asrText": {
      // 语音识别结果
      $scope.$apply(function () {
        var message = angular.fromJson(res.message);
        var results = message["results_recognition"];
      });
      break;
    }

    case "asrFinish": {
      // 语音识别功能完成
      $scope.$apply(function () {
        // TODO
      });
      break;
    }

    case "asrCancel": {
      // 语音识别取消
      $scope.$apply(function () {
        // TODO
      });
      break;
    }

    default:
      break;
  }

}, function (err) {
   alert("语音识别错误");
});

写在最后

因为对android开发并不是很熟悉,所以特此记录在开发插件的android端时遇到的一些问题

  1. 加载so库,对应不同的平台,需要添加不同平台的.so文件
