I once listened to a (human-made) audiobook where the narrator read all the mathematical notation as names of symbols ("open parenthesis open parenthesis" etc, in a discussion of lambda calculus!) So knowing how to convert the notation into natural language requires some domain knowledge beyond that of regular TTS. Maybe LLMs could help, but it's a problem to use an LLM for something where 100% accuracy is important, and there's no easy way to validate the output.
