91爆料 researchers designed a headphone system that translates several people speaking at once, following them as they move and preserving the direction and qualities of their voices. The team built the system, called Spatial Speech Translation, with off-the-shelf noise-cancelling headphones fitted with microphones.
A 91爆料 team has developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 鈥渆nroll鈥� them. The system then plays just the enrolled speaker鈥檚 voice in real time, even as the pair move around in noisy environments.
A team led by researchers at the 91爆料 has developed system of robotic self-deploying microphones, which lets users control sound in a room, muting certain areas and creating 鈥渁ctive zones鈥� in others.
A team at the 91爆料 has developed the first underwater 3D-positioning app for smart devices. When at least three divers are within about 98 feet of each other, the app tracks each user鈥檚 location relative to the leader.
