找到了我自己问题的答案,所以我将其发布给其他人使用:
为了让语音识别与蓝牙麦克风一起工作,您首先需要将设备作为蓝牙耳机对象,然后在其上调用 .startVoiceRecognition(),这会将模式设置为语音识别。
完成后,您需要调用 .stopVoiceRecognition()。
你得到蓝牙耳机是这样的:
private void SetupBluetooth()
{
btAdapter = BluetoothAdapter.getDefaultAdapter();
pairedDevices = btAdapter.getBondedDevices();
BluetoothProfile.ServiceListener mProfileListener = new BluetoothProfile.ServiceListener() {
public void onServiceConnected(int profile, BluetoothProfile proxy)
{
if (profile == BluetoothProfile.HEADSET)
{
btHeadset = (BluetoothHeadset) proxy;
}
}
public void onServiceDisconnected(int profile)
{
if (profile == BluetoothProfile.HEADSET) {
btHeadset = null;
}
}
};
btAdapter.getProfileProxy(SpeechActivity.this, mProfileListener, BluetoothProfile.HEADSET);
}
然后你会调用 startVoiceRecognition() 并像这样发送你的语音识别意图:
private void startVoice()
{
if(btAdapter.isEnabled())
{
for (BluetoothDevice tryDevice : pairedDevices)
{
//This loop tries to start VoiceRecognition mode on every paired device until it finds one that works(which will be the currently in use bluetooth headset)
if (btHeadset.startVoiceRecognition(tryDevice))
{
break;
}
}
}
recogIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recogIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
recog = SpeechRecognizer.createSpeechRecognizer(SpeechActivity.this);
recog.setRecognitionListener(new RecognitionListener()
{
.........
});
recog.startListening(recogIntent);
}
