Only Google TTS engines supported.
When will you support it?
Samsung Mobile development team do not visit this app developer forum. This is on purpose to avoid any dispute or misunderstanding of internally developed ideas. However, even if they do they would not comment on any ongoing projects or timelines for features.
This is pretty much standard for any product or software worldwide.
