I can't imagine many use cases where $1.44/hr is a significant cost.

If you sell audiobooks, then a one off cost of a few dollars to convert the book to audio form is tiny compared to the authorship of the text.

If you are doing something like turn by turn navigation, clips are typically only a few seconds long, so very cheap, and again, many of your users will be needing the same clip, so no need to pay for it twice.
