如何在 Android 手机中使用语音识别而不出现烦人的对话框

Question

不修改android API 可以实现吗？ 我找到了一篇关于此的文章。 有一个评论说我应该对 android API 进行修改。 但没有说如何修改。 有人可以给我一些关于如何做到这一点的建议吗？ 谢谢！

我找到了这篇文章； 语音识别器 他的需求和我几乎一样。 对我来说是一个很好的参考！

我已经完全解决了这个问题。
我从这个中国网站搜索了可用的示例代码 这是我的源代码

package voice.recognition.test;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
import android.util.Log;



public class voiceRecognitionTest extends Activity implements OnClickListener 
{

   private TextView mText;
   private SpeechRecognizer sr;
   private static final String TAG = "MyStt3Activity";
   @Override
   public void onCreate(Bundle savedInstanceState) 
   {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Button speakButton = (Button) findViewById(R.id.btn_speak);     
            mText = (TextView) findViewById(R.id.textView1);     
            speakButton.setOnClickListener(this);
            sr = SpeechRecognizer.createSpeechRecognizer(this);       
            sr.setRecognitionListener(new listener());        
   }

   class listener implements RecognitionListener          
   {
            public void onReadyForSpeech(Bundle params)
            {
                     Log.d(TAG, "onReadyForSpeech");
            }
            public void onBeginningOfSpeech()
            {
                     Log.d(TAG, "onBeginningOfSpeech");
            }
            public void onRmsChanged(float rmsdB)
            {
                     Log.d(TAG, "onRmsChanged");
            }
            public void onBufferReceived(byte[] buffer)
            {
                     Log.d(TAG, "onBufferReceived");
            }
            public void onEndOfSpeech()
            {
                     Log.d(TAG, "onEndofSpeech");
            }
            public void onError(int error)
            {
                     Log.d(TAG,  "error " +  error);
                     mText.setText("error " + error);
            }
            public void onResults(Bundle results)                   
            {
                     String str = new String();
                     Log.d(TAG, "onResults " + results);
                     ArrayList data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
                     for (int i = 0; i < data.size(); i++)
                     {
                               Log.d(TAG, "result " + data.get(i));
                               str += data.get(i);
                     }
                     mText.setText("results: "+String.valueOf(data.size()));        
            }
            public void onPartialResults(Bundle partialResults)
            {
                     Log.d(TAG, "onPartialResults");
            }
            public void onEvent(int eventType, Bundle params)
            {
                     Log.d(TAG, "onEvent " + eventType);
            }
   }
   public void onClick(View v) {
            if (v.getId() == R.id.btn_speak) 
            {
                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);        
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");

                intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); 
                     sr.startListening(intent);
                     Log.i("111111","11111111");
            }
   }
}

调试完后一定要删除烦人的Logs！

Answer 1

使用 SpeechRecognizer 接口。您的应用需要具有 RECORD_AUDIO 权限，然后您可以创建一个 SpeechRecognizer，为其指定一个 RecognitionListener 然后调用其 startListening 方法。当语音识别器准备好开始侦听语音以及接收语音并将其转换为文本时，您将收到对侦听器的回调。

Answer 2

GAST 有一个方便的抽象类，您可以使用它来使用 SpeechRecognizer 类，只需很少的新代码。还有一个使用 这个 和 这个

Answer 3

感谢您发布此内容！我发现在 oncreate 中定义 onclick 侦听器很有帮助：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mText = (TextView) findViewById(R.id.textView1);     
    MyRecognitionListener listener = new MyRecognitionListener();
    sr = SpeechRecognizer.createSpeechRecognizer(this);       
    sr.setRecognitionListener(listener);

    findViewById(R.id.button1).setOnClickListener( new View.OnClickListener() {
        @Override
        public void onClick(View v) 
        {
                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
                intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1); 
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");
                sr.startListening(intent);
        }
    });     
}

我最终制作了 Github 项目，将文本转换为语音，将语音转换为文本，而无需烦人的对话框，

https://github.com/hiteshsahu/Android-TTS-STT/tree/master/app/src/main/java/com/hiteshsahu/stt_tts/translation_engine

 //SPEECH TO TEXT DEMO
    speechToText.setOnClickListener({ view ->

        Snackbar.make(view, "Speak now, App is listening", Snackbar.LENGTH_LONG)
                .setAction("Action", null).show()

        TranslatorFactory
                .instance
                .with(TranslatorFactory.TRANSLATORS.SPEECH_TO_TEXT,
                        object : ConversionCallback {
                            override fun onSuccess(result: String) {
                                sttOutput.text = result
                            }

                            override fun onCompletion() {
                            }

                            override fun onErrorOccurred(errorMessage: String) {
                                erroConsole.text = "Speech2Text Error: $errorMessage"
                            }

                        }).initialize("Speak Now !!", this@HomeActivity)

    })


    //TEXT TO SPEECH DEMO
    textToSpeech.setOnClickListener({ view ->

        val stringToSpeak :String = ttsInput.text.toString()

        if (null!=stringToSpeak &&  stringToSpeak.isNotEmpty()) {

            TranslatorFactory
                    .instance
                    .with(TranslatorFactory.TRANSLATORS.TEXT_TO_SPEECH,
                            object : ConversionCallback {
                                override fun onSuccess(result: String) {
                                }

                                override fun onCompletion() {
                                }

                                override fun onErrorOccurred(errorMessage: String) {
                                    erroConsole.text = "Text2Speech Error: $errorMessage"
                                }

                            })
                    .initialize(stringToSpeak, this)

        } else {
            ttsInput.setText("Invalid input")
            Snackbar.make(view, "Please enter some text to speak", Snackbar.LENGTH_LONG).show()
        }

    })
