TL; DR: 它不起作用的原因是因为我在 Android 6.0 上运行该应用程序。在 6.0 中，您必须手动授予应用程序访问麦克风的权限。
原帖: 我想创建一个使用 speechRecognition 的 ionic 应用程序 https://github.com/macdonst/SpeechRecognitionPlugin
但不知为什么它不起作用？
首先我创建了一个 ionic 项目:
ionic start cordova-speech blank
我进入那个新文件夹并下载了插件:
cordova plugin add https://github.com/macdonst/SpeechRecognitionPlugin
然后我添加了android平台。
我的 HTML 文件:
<body ng-app="starter">
<ion-pane ng-controller="AppCtrl">
<ion-content class="padding">
<button class="button button-full button-positive" ng-click="record()">
Record
</button>
<div class="card">
<div class="item item-text-wrap">
{{recognizedText}}
</div>
</div>
</ion-content>
</ion-pane>
</body>
我的 app.js 文件:
angular.module('starter', ['ionic'])
.controller('AppCtrl', function($scope) {
$scope.recognizedText = '';
$scope.record = function() {
alert("step1");
var recognition = new SpeechRecognition();
alert("step2");
recognition.onresult = function(event) {
alert("step3");
if (event.results.length > 0) {
$scope.recognizedText = event.results[0][0].transcript;
$scope.$apply();
}
};
recognition.start();
alert("step4");
};
});
我在代码中添加了一些警报以便进行调试(无法在浏览器中调试该功能)。当我按下录制按钮时，它只会弹出第一个和第二个警报。问题似乎与结果有关。我错过了什么？
我使用的是 Android 6.0
我做了一个 adb logcat。这是结果:

更新: 我安装了
cordova plugin add cordova-plugin-chrome-apps-audiocapture --save
ordova plugin add org.apache.cordova.media
有人说我应该删除
<uses-permission android:name="android.permission.RECORD_AUDIO" />
来 self 的 speechrecognition 和 cordova 媒体插件，但它也无济于事。它现在执行第 4 个警报但跳过警报 3，这意味着 onresult 函数仍然存在问题。
最佳答案
日志中的这一行:
02-14 03:39:29.569 30081 30096 E RecognitionService: call for recognition service without RECORD_AUDIO permissions
告诉您需要设置权限才能在您的应用程序中录制音频。您可以添加插件 org.apache.cordova.media
cordova plugin add org.apache.cordova.media
