如何将文本添加到印地语的语音？

Question

我的应用程序包含两个字符串和两个按钮，一个英文字符串和印地语字符串，当我点击英语说话按钮时，英语字符串正在发音，当我来到印地语字符串它是不响应给定的单词有人提到。

这里是我的MainActivity看喜欢，

public class MainActivity extends AppCompatActivity { 

private TextView englishString, hindiString; 
private Button englishButton, hindiButton; 
private TextToSpeech textToSpeech; 

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

    englishString = (TextView) findViewById(R.id.englishString); 
    hindiString = (TextView) findViewById(R.id.hindiString); 

    englishButton = (Button) findViewById(R.id.englishButton); 
    hindiButton = (Button) findViewById(R.id.hindiButton); 

    englishButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      loadSpeakingLanguages(englishString.getText().toString()); 
     } 
    }); 

    hindiButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      loadSpeakingLanguages(hindiString.getText().toString()); 
     } 
    }); 
} 


private void loadSpeakingLanguages(String textToTranslate) { 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     ttsGreater21(textToTranslate); 
    } else { 
     ttsUnder20(textToTranslate); 
    } 
} 

@SuppressWarnings("deprecation") 
private void ttsUnder20(String text) { 
    HashMap<String, String> map = new HashMap<>(); 
    map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "MessageId"); 
    textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, map); 
} 

@TargetApi(Build.VERSION_CODES.LOLLIPOP) 
private void ttsGreater21(String text) { 
    String utteranceId = this.hashCode() + ""; 
    textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, utteranceId); 
} 


@Override 
protected void onResume() { 
    textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() { 
     @Override 
     public void onInit(int status) { 
      if (status != TextToSpeech.ERROR) { 
       textToSpeech.setLanguage(Locale.ENGLISH); 
      } 
     } 
    }); 
    super.onResume(); 
} 

public void onPause() { 
    if (textToSpeech != null) { 
     textToSpeech.stop(); 
     textToSpeech.shutdown(); 
     textToSpeech = null; 
    } 
    super.onPause(); 
}} 

这里是我的activity_main样子，

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="ravi.texttospeech.MainActivity"> 

<TextView 
    android:id="@+id/englishString" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Hello World!" 
    android:textSize="25dp" /> 

<TextView 
    android:id="@+id/hindiString" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/englishString" 
    android:text="नमस्ते दुनिया" 
    android:textSize="25dp" /> 

<Button 
    android:id="@+id/englishButton" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/hindiString" 
    android:text="Speak English Text" /> 

<Button 
    android:id="@+id/hindiButton" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/englishButton" 
    android:text="Speak Hindi Text" /> 

And here is how my app look like

Answer 1

我在代码中完成了的一些修改。

hindiButton.setOnClickListener(new View.OnClickListener() { 
     @TargetApi(Build.VERSION_CODES.LOLLIPOP) 
     @Override 
     public void onClick(View view) { 
      loadSpeakingLanguages(hindiString.getText().toString()); 
      textToSpeech.setLanguage(Locale.forLanguageTag("hin")); 
     } 
    }); 

它对我工作很好。

您需要使用ISO 639 3个字母的单词或ISO 639 2个字母的单词
