我使用在線教程製作了聊天機器人，現在除了在編輯文本中編寫輸入外，我還使用語音識別。但問題是當我按下語音識別按鈕時，tts不工作。我不知道我使用各種方法的問題是什麼。從編輯文本字段發送文本時，tts可以正常工作。這裏是主要活動中兩個代碼的示例。第一個代碼是通過發送按鈕發送文本，工作正常。第二個代碼是我使用stt聊天並且不工作的wone。需要幫助解決問題。提前致謝。我的文本到語音不起作用，當我在android chatbot中輸入文字作爲輸入時
public class MainActivity extends AppCompatActivity {
private ListView mListView;
private FloatingActionButton mButtonSend;
private EditText mEditTextMessage;
private ImageView mImageView;
public Bot bot;
public static Chat chat;
private ChatMessage.ChatMessageAdapter mAdapter;
public Button buSpeak;
public TextToSpeech tts;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR){
tts.setLanguage(Locale.US);
}
}
});
mListView = (ListView) findViewById(R.id.listView);
mButtonSend = (FloatingActionButton) findViewById(R.id.btn_send);
mEditTextMessage = (EditText) findViewById(R.id.et_message);
mImageView = (ImageView) findViewById(R.id.iv_image);
mAdapter = new ChatMessage.ChatMessageAdapter(this, new ArrayList<ChatMessage>());
mListView.setAdapter(mAdapter);
buSpeak = (Button)findViewById(R.id.buSpeak);
CheckUserPermsions();
//chat button
mButtonSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String message = mEditTextMessage.getText().toString();
//bot
String response = chat.multisentenceRespond(mEditTextMessage.getText().toString());
if (TextUtils.isEmpty(message)) {
return;
}
sendMessage(message);
mimicOtherMessage(response);
mEditTextMessage.setText("");
mListView.setSelection(mAdapter.getCount() - 1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
tts.speak(response, TextToSpeech.QUEUE_FLUSH,null,null);
}else{
tts.speak(response, TextToSpeech.QUEUE_FLUSH,null);
}
}
});
和使用語音識別的代碼，這裏的TTS不工作
public void buSpeak(View view) {
startVoiceRecognitionActivity();
}
private void startVoiceRecognitionActivity() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
//since you only want one, only request 1
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
startActivityForResult(intent, 1234);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK){
tts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR){
tts.setLanguage(Locale.US);
}
}
});
//pull all of the matches
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String topResult = matches.get(0);
EditText AutoText = (EditText) findViewById(R.id.et_message);
AutoText.setText(topResult);
String message = AutoText.getText().toString();
//bot
String response = chat.multisentenceRespond(AutoText.getText().toString());
if (TextUtils.isEmpty(response)) {
return;
}
sendMessage(message);
mimicOtherMessage(response);
AutoText.setText("");
mListView.setSelection(mAdapter.getCount() - 1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
tts.speak(response, TextToSpeech.QUEUE_FLUSH,null,null);
}else{
tts.speak(response, TextToSpeech.QUEUE_FLUSH,null);
}
}
}
public void CheckUserPermsions(){
if (Build.VERSION.SDK_INT >= 23){
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED ){
requestPermissions(new String[]{
android.Manifest.permission.READ_EXTERNAL_STORAGE},
REQUEST_CODE_ASK_PERMISSIONS);
return ;
}
}
}
//get acces to location permsion
final private int REQUEST_CODE_ASK_PERMISSIONS = 123;
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_CODE_ASK_PERMISSIONS:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
} else {
// Permission Denied
Toast.makeText(this,"denail" , Toast.LENGTH_SHORT)
.show();
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
public void onPause(){
if(tts !=null){
tts.stop();
tts.shutdown();
}
super.onPause();
}
}
感謝。好，但我只需要chatbot的迴應就可以說話。我從語音中輸入內容，並且工作正常。並在onActivityResult方法上自動響應機器人響應。它直接在聊天屏幕上顯示機器人的回覆，但它不會說話。第一個代碼是我用來輸入的代碼，答案是tts完美。第二個代碼tts在使用按鈕直接回復時不起作用。 – Shahriar
