SpeechRecognizer
类来处理语音输入。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 VoiceActivity extends AppCompatActivity {, private SpeechRecognizer speechRecognizer;,, @Override, protected void onCreate(Bundle savedInstanceState) {, super.onCreate(savedInstanceState);, setContentView(R.layout.activity_voice);,, 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 text = matches.get(0);, // 处理识别到的文本, }, },, @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基本的语音识别界面,当用户说话时,会将识别到的文本进行处理。unset
