RecognizerIntent.ACTION_RECOGNIZE_SPEECH 在新的 Android 设备中不起作用

以下是我的语音识别代码，对于最新的设备和平板电脑，它显示“识别器不存在”。请帮助我如何修复它。

public void startMyVoice()
{   
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);   
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, sayClose);   
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");

try 
{
    startActivityForResult(intent, RESULT_SPEECH);      
} 
catch (ActivityNotFoundException a) 
{                   
    Toast.makeText(getApplicationContext(), "Recogniser not present", Toast.LENGTH_SHORT).show();      
}

}

根据this https://developer.android.com/training/package-visibility文档：

当应用面向 Android 11（API 级别 30）或更高版本时...要查看其他包，请使用<queries>元素。

所以如果你正在使用RecognizerIntent.ACTION_RECOGNIZE_SPEECH，那么你需要声明相同的intent https://developer.android.com/reference/android/speech/RecognizerIntent#ACTION_RECOGNIZE_SPEECH in AndroidManifest.xml外部<application>像这样的标签：

<manifest>

    ...

    <queries>
        <intent>
            <action android:name="android.speech.action.RECOGNIZE_SPEECH" />
        </intent>
    </queries>
</manifest>

否则pm.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);将始终返回一个空列表。
