If you also gave all that text, with its audio, to the putative AI, it might have enough training material to learn to read your handwriting.
And, doh, took a minute, and realized I'm a dunce.* And now there's at least 3 I can think of off the top of my head, not to mention local.
Training a handwriting recognition AI is universally accessible. What a time to be alive.
* If you're dense like me: they're not saying "any AI" as "any handwriting recognition machine learning model you build from that dataset". They're saying as AI as any multimodal LLM, it'll do in context learning on what you upload.
