答
这可能是一个评论,我不知道,但你可以尝试 变化if (Text2SpeechCurrentStatus == TextToSpeech.SUCCESS) {
到if (Text2SpeechCurrentStatus != TextToSpeech.ERROR) {
也许你可以调试,什么是Text2SpeechCurrentStatus
答
首先,最重要的是:检查是否有任何TTS引擎安装在您的设备中。
并且不,您不需要任何使用TTS的权限。
在此活动的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);
}
希望它可以帮助...
