Abstract
This document relates to distributed teleconferencing. Some implementations can employ personalized enhancement models to enhance microphone signals for participants in a call. Further implementations can perform proximity-based mixing, where microphone signals received from devices in a particular room can be omitted from playback signals transmitted to other devices in the same room. These techniques can allow enhanced call quality for teleconferencing sessions where co-located users can employ their own devices to participate in a call with other users.
Claims20
A method comprising:
- receiving an enhanced first microphone signal, the enhanced first microphone signal having been produced by enhancing a first microphone signal captured by a first device using a first personalized enhancement model that has been adapted for a first user of the first device;
- receiving an enhanced second microphone signal, the enhanced second microphone signal having been produced by enhancing a second microphone signal captured by a second device using a second personalized enhancement model that has been adapted for a second user of the second device;
- mixing the enhanced first microphone signal with the enhanced second microphone signal to obtain a playback signal;
- and
- sending the playback signal to a third device that is participating in a call with the first device and the second device.
A method comprising:
- receiving a first microphone signal from a first device;
- receiving a second microphone signal from a second device that is co-located with the first device;
- mixing the first microphone signal with the second microphone signal to obtain a playback signal;
- sending the playback signal to a third device that is participating in a call with the first device and the second device;
- and
- sending another playback signal to at least one of the first device or the second device, the another playback signal omitting the first microphone signal and the second microphone signal.
A system comprising:
- a processor;
- and
- a storage medium storing instructions which, when executed by the processor, cause the system to:
- receive an enhanced first microphone signal from a first device, the enhanced first microphone signal having been enhanced by a first personalized enhancement model that has been adapted for a first user of the first device;
- receive an enhanced second microphone signal from a second device that is co-located with the first device, the enhanced second microphone signal having been enhanced by a second personalized enhancement model that has been adapted for a second user of the second device;
- mix the enhanced first microphone signal with the enhanced second microphone signal to obtain a playback signal;
- and
- send the playback signal to a third device that is participating in a call with the first device and the second device.
