SpeechRecognizer类。以下是一个简单的示例代码：，，``java，import android.content.Intent;，import android.os.Bundle;，import android.speech.RecognitionListener;，import android.speech.RecognizerIntent;，import android.speech.SpeechRecognizer;，import androidx.appcompat.app.AppCompatActivity;，import java.util.ArrayList;，，public class MainActivity extends AppCompatActivity {， private SpeechRecognizer speechRecognizer;，， @Override， protected void onCreate(Bundle savedInstanceState) {， super.onCreate(savedInstanceState);， setContentView(R.layout.activity_main);，， speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);， speechRecognizer.setRecognitionListener(new RecognitionListener() {， @Override， public void onReadyForSpeech(Bundle params) {}，， @Override， public void onBeginningOfSpeech() {}，， @Override， public void onRmsChanged(float rmsdB) {}，， @Override， public void onBufferReceived(byte[] buffer) {}，， @Override， public void onEndOfSpeech() {}，， @Override， public void onError(int error) {}，， @Override， public void onResults(Bundle results) {， ArrayList matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);， if (matches != null && !matches.isEmpty()) {， String recognizedText = matches.get(0);， // 处理识别结果， }， }，， @Override， public void onPartialResults(Bundle partialResults) {}，， @Override， public void onEvent(int eventType, Bundle params) {}， });，， Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);， intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);， intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);， speechRecognizer.startListening(intent);， }，， @Override， protected void onDestroy() {， super.onDestroy();， if (speechRecognizer != null) {， speechRecognizer.destroy();， }， }，}，`，，这段代码创建了一个SpeechRecognizer实例，并设置了一个RecognitionListener来处理语音识别的结果。通过调用startListening`方法启动语音识别，并在识别完成后处理结果。nslookup或ping，也可以访问在线DNS查询服务。Powered By Z-BlogPHP 1.7.3
