"while I'm no expert, I've never heard of a call center system that can accept touch tones seamlessly while a call is active, and it would take extremely sophisticated audio processing capabilities to be able to do that, since the frequencies used by touch tone keys heavily overlap the frequencies of human speech."
"Extremely sophisticated?" The tones are just a sum of two sine waves of known frequencies. That's trivial to detect. What am I missing?
- Nextgrid 5y agoI think his point was that it's difficult for a system to conceal the tones from the other party while not interfering with normal speech.
- monktastic1 5y agoDid you read it in context? It seems very clear to me that he's talking about detecting the tones.
