I heard about VocalZoom at the Embedded Online Conference, who are trying a hardware approach to solving the cocktail party effect.
Basically they use lasers and directional microphones. Seems like it could work for a conference call in a meeting room, but not sure how helpful it would be for a party.
I'm more interested in the SRAY: a directional loudspeaker, which could avoid the need for so much ambient background noise. Also useful for alarm clocks, I suppose.
