Thanks! The bulk of the cost is using OpenAI’s text-to-speech API, which is $0.015 per 1,000 characters. Oration generates both a full and summarized audiobook as well. So far, I’ve found that service to provide a really good price and quality level, compared to offerings from AWS, Azure and other vendors. If you happen to be an iOS user, give the app a try! (https://oration.app https://oration.app) The iOS app is completely free for the time being, so we can focus on really giving our users a great experience. Eventually, I plan to introduce some paid plans but will keep a generous free tier.
