问题描述
我以“印地语”语言实现了文本到语音的转换,这是我的印度语言,我的应用程序在API级别29之前运行良好。 它对英语有效,但对印地语则不行。 但是在API级别为30的新设备中,它不起作用。 在API级别30的设备中调试其给定结果值-2“无语言支持的错误”。
private void setTextTospeech() {
textToSpeech = new TextToSpeech(mContext,new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
if (language.toLowerCase().contains(langaugeCodeEnglish)) {
int result = textToSpeech.setLanguage(new Locale("en","IN"));
if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
//Toast.makeText(mContext,result + " is not supported",Toast.LENGTH_SHORT).show();
Log.e("Text2SpeechWidget",result + " is not supported");
}
} else {
int result = textToSpeech.setLanguage(new Locale("hi","IN"));
if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
textToSpeech.setLanguage(Locale.forLanguageTag("hin"));
} else {
// Toast.makeText(mContext,result + "Language is not supported",Toast.LENGTH_SHORT).show();
Log.e("Text2SpeechWidget",result + "Language is not supported");
}
Log.e("Text2SpeechWidget",result + " is not supported");
}
}
}
}
});
}
private void speak(String s,String text) {
try{
float pitch = (float) 0.62;
float speed = (float) 0.86;
textToSpeech.setSpeechRate(speed);
textToSpeech.setPitch(pitch);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Bundle bundle = new Bundle();
bundle.putInt(TextToSpeech.Engine.KEY_ParaM_STREAM,AudioManager.STREAM_MUSIC);
textToSpeech.speak(s,TextToSpeech.QUEUE_FLUSH,bundle,null);
textToSpeech.speak(text,TextToSpeech.QUEUE_ADD,null);
} else {
HashMap<String,String> param = new HashMap<>();
param.put(TextToSpeech.Engine.KEY_ParaM_STREAM,String.valueOf(AudioManager.STREAM_MUSIC));
textToSpeech.speak(s,param);
textToSpeech.speak(text,param);

<queries>
...
<intent>
<action android:name="android.intent.action.TTS_SERVICE" />
</intent>
</queries>
解决方法
在manifest文件中添加如下权限;
使用权限 android:name="android.permission.QUERY_ALL_PACKAGES"
,谢谢穆斯塔法巴林
android studio 让我改变了一点。
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"
tools:ignore="QueryAllPackagesPermission" />
