Changing the default voice of Android's Text To Speech

Question

I\'m using the Android\'s Text To Speech default engine in my app, however the female\'s voice sounds like a woman over 40 and her voice is somewhat robotic.

Answer 1

Here is my code to use KEY_FEATURE_NETWORK_SYNTHESIS param:

HashMap onlineSpeech = new HashMap<>();
onlineSpeech.put(TextToSpeech.Engine.KEY_FEATURE_NETWORK_SYNTHESIS, "true");
tts.speak(speech, TextToSpeech.QUEUE_FLUSH, onlineSpeech);
