![]() ![]() Across all these environments, the system could discern different voices within 1.6 feet (50 centimeters) of each other 90% of the time, without prior information about the number of speakers. The team tested the robots in offices, living rooms and kitchens with groups of three to five people speaking. So you can have four people having two conversations and isolate any of the four voices and locate each of the voices in a room." "We developed neural networks that use these time-delayed signals to separate what each person is saying and track their positions in a space. If someone else is closer to the microphone that's two feet away, their voice will arrive there first," said co-lead authorTuochao Chen, a UW doctoral student in the Allen School. "If I have one microphone a foot away from me, and another microphone two feet away, my voice will arrive at the microphone that's a foot away first. Today's consumer smart speakers have multiple microphones, but clustered on the same device, they're too close to allow for this system's mute and active zones. The robots disperse as far from each other as possible since greater distances make differentiating and locating people speaking easier. The automatic deployment allows the robots to place themselves for maximum accuracy, permitting greater sound control than if a person set them. As they move from their charger, each robot emits a high frequency sound, like a bat navigating, using this frequency and other sensors to avoid obstacles and move around without falling off the table. The team's prototype consists of seven small robots that spread themselves across tables of various sizes. The UW team's system is the first to accurately distribute a robot swarm using only sound. Previous research on robot swarms has required using overhead or on-device cameras, projectors or special surfaces. "For the first time, using what we're calling a robotic 'acoustic swarm,' we're able to track the positions of multiple people talking in a room and separate their speech." Allen School of Computer Science & Engineering. Until now, it's also been difficult for technology," said co-lead author Malek Itani, a UW doctoral student in the Paul G. That's extremely hard for the human brain to process. "If I close my eyes and there are 10 people talking in a room, I have no idea who's saying what and where they are in the room exactly. In a conference room meeting, for instance, such a system might be deployed instead of a central microphone, allowing better control of in-room audio. This allows the system to be moved between environments and set up automatically. Like a fleet of Roombas, each about an inch in diameter, the microphones automatically deploy from, and then return to, a charging station. With the help of the team's deep-learning algorithms, the system lets users mute certain areas or separate simultaneous conversations, even if two adjacent people have similar voices.

To quickly get off mute the person dialed into the meeting would simply need to press *6 to toggle the mute / unmute feature. Today you currently can’t tell if the person who is dialed into the conference is on mute or not. If you ever run into this situation, it may mean that the person who dialed into the meeting is on mute. Or the worst part you are the person who is dialed into a meeting and no one can hear you. You call upon someone in the meeting who may have been dialed in, and you hear no response. Ok, you are in a meeting, maybe some background noise was introduced into the call, and you quickly utilize the “Mute All” button to get rid of the noise.
