Sci-fi narration depends on range, delivering world-building, invented terminology, and alien names convincingly from one scene to the next. koolio's voice generator lets you set the mood and delivery for each segment individually, from a whisper to a loud, authoritative tone, and you can preview how a chapter sounds before committing to a full narrator.
