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
