我试图使用TextToSpeech
类在我的应用中说文字。运行代码时,我听不到任何声音,音量很高。我的代码有什么问题?我需要许可或其他任何东西吗?
public class MainActivity extends AppCompatActivity implements TextToSpeech.OnInitListener {
TextToSpeech textToSpeech;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textToSpeech = new TextToSpeech(this, this);
speakOut();
}
@Override
public void onInit(int Text2SpeechCurrentStatus) {
if (Text2SpeechCurrentStatus == TextToSpeech.SUCCESS) {
int result = textToSpeech.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "This Language is not supported");
} else {
speakOut();
}
} else {
Log.e("TTS", "Initilization Failed!");
}
}
private void speakOut() {
String g= "Hello";
textToSpeech.speak(g, TextToSpeech.QUEUE_FLUSH, null);
}
}
最佳答案
首先,最重要的是:检查设备中是否装有TTS引擎。
不,您不需要任何许可即可使用TTS。
像这样在活动的onCreate()方法中初始化TextToSpeech实例。
TextToSpeech t1=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
t1.setLanguage(Locale.UK);
}
}
});
//这是您的
speakOut()
方法。 private void speakOut() {
String g= "Hello";
t1.speak(g, TextToSpeech.QUEUE_FLUSH, null);
}
希望能帮助到你...
