Android ACTION_RECOGNIZE_SPEECH 意图在长篇大论之后永远不会结束

Question

我开始打算并等待结果。它在简短的演讲中效果很好，但如果演讲太长，它不会给我答案。（将近 1 分钟）

final Intent searchIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

    searchIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "tr");
    searchIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, true);
    searchIntent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE, true);

    startActivityForResult(searchIntent, VOICE_REQUEST_CODE);

除了 SpeechRecognizer 之外，还有其他方法可以从 ACTION_RECOGNIZE_SPEECH 意图中获取结果吗？

Answer 1

试试这个 google 文本到语音意图启动器，

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak Now");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, REQUEST_CODE);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
startActivityForResult(intent,REQUEST_CODE);

希望这对您有所帮助:)

Answer 2

这是一个可行的解决方案：

final Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, yourPackageHere);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1000);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Your Prompt");
startActivityForResult(intent,REQUEST_CODE);

但在使用此功能之前，您应该检查用户是否授予 RECORD_AUDIO 权限以及设备是否有 ACTION_RECOGNIZE_SPEECH 可用。

识别语音对长语音有一个有趣的行为。如果您给 MAX_RESULTS 一个小数字，识别语音屏幕会在长时间语音后冻结。所以你需要保持数字更大，你会从识别语音意图中得到 onActivityResult 和 List<String> results 的结果。您可以通过循环获得结果，而不是使用。

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_CODE_SPEECH_INPUT =1000 ;
    //views from activity
    TextView mTextTv;
    ImageButton mVoiceBtn;

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

        mTextTv= findViewById( R.id.textTv );
        mVoiceBtn=findViewById( R.id.voiceBtn );

        //button clic to show speech to text dilog
        mVoiceBtn.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                speak();
            }
        } );
    }

    private void speak() {
        //intent is show speech to text dialog
        Intent intent= new Intent( RecognizerIntent.ACTION_RECOGNIZE_SPEECH );
        intent.putExtra( RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra( RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault() );
        intent.putExtra( RecognizerIntent.EXTRA_PROMPT, "HI speak something" );

        // Start intent
        try {
            //in there was no errror
            //show dilog
            startActivityForResult( intent, REQUEST_CODE_SPEECH_INPUT);
        }

        catch(Exception e){
            //show messageof error and show
            Toast.makeText( this,""+e.getMessage(), Toast.LENGTH_SHORT ).show();
        }
    }
    //recive voice input and handle it

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult( requestCode, resultCode, data );

        switch (requestCode){
            case REQUEST_CODE_SPEECH_INPUT:{
                if(resultCode==RESULT_OK && null!=data){
                    //get text arry form voice intent
                    ArrayList<String> result=data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS );
                    //set to text view
                    mTextTv.setText( result.get( 0 ) );
                }
                break;

            }
        }
    }
}
