I'm working on making my first Android App, and I cannot get the text to speech to work.
The gist of the app: user selects the time they want to set an alarm (using a TimePicker), then the app calculates the amount of time left, continuously updating the amount of time left.
I want the use the text to speech engine to verbally update the user at 5 minute intervals on how much time they have left.
Everything compiles and runs without error, but the text to speech just doesn't do anything. I've looked for days to find out how to properly initialize the TextToSpeech class in java, but everything I find seems to initialize it differently on a case by case basis.
After trying multiple different implementations, all with the same result, I decided to just make a separate inner class to make editing and trying new things easier, and I can just make a Voice class and call methods on it.
I've only been coding in Java for a few months, and this is my first Android App, so I am having a lot of trouble sorting through this on my own.
Below is the separate (inner/nested) class that I am using to initialize the TextToSpeech class:
private class Voice implements TextToSpeech.OnInitListener {
Context context = getApplicationContext();
TextToSpeech tts = new TextToSpeech(context, this);
public void onInit(int initStatus) {
if (initStatus == TextToSpeech.SUCCESS) {
tts.setLanguage(Locale.US);
}
}
private void say(String announcement) {
tts.speak(announcement, TextToSpeech.QUEUE_FLUSH, null);
}
}
Here is the rest of the code in the activity ( I use a separate activity to display the countdown)
