@neurovagrant Holy shit. This was my career and I cannot even.
I remember calls that went both ways. Ones where tone of voice and evasive answers sent up red flags. Another where someone called yelling they'd been robbed, and it was the fact they sounded utterly pissed that clued me off (it was a civil dispute with a cab driver, not an emergency).
How the hell would an AI understand when someone talking suddenly starts screaming incoherently?
