我正在开发一个应用程序，我想在其中通过语音输入使用从印地语到英语的音译。为此，我正在使用谷歌 STT API。当我的语音输入很短时，一切正常，但是当我输入很长的语音时，Dialog 会卡在“尝试说点什么……”，而且我没有得到很好的结果。
这是我的主要 Activity :-
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
// Record Button
AppCompatButton RecordBtn;
// TextView to show Original and recognized Text
TextView Original,result;
// Request Code for STT
private final int SST_REQUEST_CODE = 101;
// Conversion Table Object...
ConversionTable conversionTable;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Original = findViewById(R.id.Original_Text);
RecordBtn = findViewById(R.id.RecordBtn);
result = findViewById(R.id.Recognized_Text);
RecordBtn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.RecordBtn:
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// For 30 Sec it will Record...
intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 30);
// Use Off line Recognition Engine only...
intent.putExtra(RecognizerIntent.EXTRA_PREFER_OFFLINE, false);
// Use Hindi Speech Recognition Model...
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "hi-IN");
try {
startActivityForResult(intent, SST_REQUEST_CODE);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.error),
Toast.LENGTH_SHORT).show();
}
break;
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case SST_REQUEST_CODE:
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> getResult = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
Original.setText(getResult.get(0));
conversionTable = new ConversionTable();
String Transformed_String = conversionTable.transform(getResult.get(0));
result.setText(Transformed_String);
}
break;
}
}
}

最佳答案
问题在于 Google 的实现。我遇到了同样的困难并尝试了所有的事情，但没有做任何事情。
所以，我采用了另一种方法来解决这个问题，解决方案是自己实现监听器。这是我的代码，它从不弹出内置对话框(您可以实现您的自定义对话框)，但它就像魅力一样。
这里是你如何做到的:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
// Record Button
AppCompatButton RecordBtn;
// TextView to show Original
TextView Original;
// SpeechRecognizer Object...
private SpeechRecognizer speechRecognizer;
// For TAG
private String TAG = getClass().getName();
// RecognizerIntent
private Intent recognizerIntent;
// Request Code for Permission
private static final int REQUEST_CODE_RECORD_AUDIO = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Original = findViewById(R.id.Original_Text);
RecordBtn = findViewById(R.id.RecordBtn);
recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, R.string.record);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
recognizerIntent.putExtra(RecognizerIntent.EXTRA_PREFER_OFFLINE, false);
}
// For 30 Sec it will Record...
recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 30);
// Use Hindi Speech Recognition Model...
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "hi-IN");
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
// Permission Dialog
Askpermission();
RecordBtn.setOnClickListener(this);
}
private void Askpermission() {
// No explanation needed; request the permission
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.RECORD_AUDIO},
REQUEST_CODE_RECORD_AUDIO);
}
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String permissions[], @NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_RECORD_AUDIO: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Operation();
