[英]How to implement voice command recognition in android?
Hello I want build an app where my android app recognize my voice command & perform certain task. 您好,我想构建一个我的Android应用能够识别我的语音命令并执行某些任务的应用。 i have searched a lot but didn't find any valid solution. 我已经搜索了很多,但没有找到任何有效的解决方案。 Kindly tell how to implement it? 请告诉我如何执行它?
you may take a look at this question if you want offline speech recognition: 如果您要离线语音识别,可以查看以下问题 :
But there is also a another solution: 但是还有另一个解决方案:
You can use this app which is made by google a few years ago. 您可以使用几年前由Google制造的此应用 。 just install this app in your device and then simply call that app : 只需在您的设备中安装此应用,然后只需调用该应用即可:
private void startRecognizeSpeech() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
try {
startActivityForResult(intent, RESULT_SPEECH);
} catch (ActivityNotFoundException a) {
Toast.makeText(
getApplicationContext(),
"Oops! First you must download \"Voice Search\" App from Store",
Toast.LENGTH_SHORT).show();
}
}
Then in onActivityResult() do this : 然后在onActivityResult()中执行以下操作:
@Override
// calls when voice recognition result received
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_SPEECH: {
if (resultCode == RESULT_OK && null != data) {
// text is received form google
ArrayList<String> text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
//you can find your result in text Arraylist
}
break;
}
}
}
