我正在尝试使用TextToSpeech
类在我的应用中说出文字。当我运行我的代码时,我没有听到任何声音,音量很高。我的代码出了什么问题?我需要许可还是其他什么?
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);
}
}

首要的事情是:检查设备中是否装有任何TTS引擎。
不,你不需要任何使用TTS的许可。
在活动的onCreate()方法中初始化TextToSpeech实例,如下所示。
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);
}
希望它有所帮助...

这可能是评论,我不确定,但你可以试试
改变
if (Text2SpeechCurrentStatus == TextToSpeech.SUCCESS) {
进入
if (Text2SpeechCurrentStatus != TextToSpeech.ERROR) {
也许你可以调试,Text2SpeechCurrentStatus
