如何使用语音控制音乐播放器

Question

我正在开发一个应用程序，它可以使用语音控制音乐播放器。例如，当我说“播放”音乐播放器播放歌曲，或者说“下一个”音乐播放器将播放下一首歌曲等。我已经Google，但没有找到任何想法或源代码。

问题：

1. 理念使用语音

2. 源代码示例来控制音乐播放器。

提前致谢。

您将需要此：

private void playNextMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_NEXT)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_NEXT)); 
    sendOrderedBroadcast(i, null); 

    playPlayMusic(); 
} 

private void playPreviousMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PREVIOUS)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PREVIOUS)); 
    sendOrderedBroadcast(i, null); 

    playPlayMusic(); 
} 

private void playPauseMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PAUSE)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PAUSE)); 
    sendOrderedBroadcast(i, null); 
} 

private void playPlayMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY)); 
    sendOrderedBroadcast(i, null); 
} 

private void playStopMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_STOP)); 
    sendOrderedBroadcast(i, null); 
}
