I have a question for AI/NLP experts (and I might use the wrong terms).

When our voices are processed in systems like these are the results compared to a corpus of our own speech, a local (geo) population, or language speakers as a whole?

I’ve been curious how slang and people with poor grammar affect results of other users. Will we start seeing “thicc” instead of “thick” and “dat” instead of “that” over time?

One of the reasons I’ve been pondering this (anecdote alert) is that I frequently see iOS dictation spelling bizarrely.
