Android Text to speech And Speech to text

Question

I am working with text to speech and speech to text at the same time. I am making an app in which it ask a question through text to speech and get the answer from the user through speech and app convert it to text. but it does not work fine. both are working at the same time like what it speak, it text it back. can we give some delay so that when it stop speaking then it listen for the voice and return that text. `

Answer 1

Try changing:

speakOut();
promptSpeechInput();

to

promptSpeechInput();

And then add:

speakOut();

after

eText1.setText(result.get(0));

This should speak the text after it has finished getting the text

Edit: use this to determine when the speech is finished. When it is just call promptSpeechInput()
