Why it works for documentary narration

A measured delivery that lasts the full runtimeDocumentary narration runs long, and a narrator who changes character halfway through is distracting. Every section is generated with the same voice and settings, so the delivery in the final act matches the opening.
Built for an edit that keeps changingPicture edits move narration. Each generated section is stored separately, so when a line is rewritten you regenerate that section and leave the rest of the narration, and the timing your editor built around it, untouched.
Real names, places, and datesHistorical and scientific documentaries are full of names that text to speech can get wrong. Fix a reading once in your pronunciation dictionary and it holds for every passage and every revision.
Subtitles and levels ready for the timelineThe SRT is rebuilt from the final assembled audio, and exports are normalized to -16 LUFS so the narration sits at a predictable level when it lands in your editor.
