Sorry if this is in that article, but I am on my phone and can't see it. How much would this cost to batch generate an audiobook? Right now I just listen to things in the 11 labs app which is free, but I would rather just generate audio files.

Roughly 5-10$ for 10h, assuming you few-shot it.

Price per hour:

- 3.8 Flash TTS, standard: $0.81

- 3.8 Flash TTS, batch: $0.41

- 3.8 Flash‑Lite TTS, standard: $0.54

- 3.8 Flash‑Lite TTS, batch: $0.27

That is the biggest difference here for me. I have not looked at every solution, but many. They are either much more expensive or garbage quality. For example my next target audiobook is a monster 250k words, 1.5m characters, so about $15 here or $75 using elevenlabs (0.05 per 1k characters). For me that is the difference between I will or I won't use it.

Until the end of the year, then double that. And that's only the audi output though the text input shouldn't cost much in comparison.
