Ah, sorry, I should clarify that when I say "talk", I didn't mean it in the literal sense. I've only worked on text as a source, though Speech-to-text shouldn't be too hard to integrate if it was needed.

I like your insight about using... let's call them "key phrases"...to help guide the query. Perhaps having a way to map a key phrase with a specific query, maybe one that is parameterized, would be useful. thank you.
