It is good that Audemic skips Mathematical Formulae instead of just saying the characters, but It is missing important information. It would be great to add support for reading mathematical formulas.
I agree, this is something I have actually been looking for. All TTS apps struggle with this. If this was implemented, it would really set this app apart from the rest (seems like a hard problem if no one has figured out a solution yet). Formulas are very important in my research and it is essential for understanding what is going on.
If you are able to get the formulas as text, I recommend spending some time/effort/money on building a dataset of the textual natural language version of the formula, then fine-tuning a language model for this task.
As users already have to wait a decent amount of time for the audio to render in your app, whats a couple extra seconds? However, you should probably work on this latency issue because I was quite shocked how long it took the first time I used the app.
