Calls TTS with one of a set of preset generation parameters. Options:
'intelligible': Maximizes the probability of understandable words at the cost of diverse voices, intonation and prosody.
'realistic': Increases the diversity of spoken voices and improves realism of vocal characteristics at the cost of intelligibility.
'mid': Somewhere between 'intelligible' and 'realistic'.
'ultra_fast': Produces speech at a speed which belies the name of this repo. (Not really, but it's definitely fastest).
'fast': Decent quality speech at a decent inference rate. A good choice for mass inference.
'standard': Very good quality. This is generally about as good as you are going to get.
'high_quality': Use if you want the absolute best. This is not really worth the compute, though.
