Talking in a noisy place is difficult, especially for people with hearing loss. A team made smart headphones that use artificial intelligence to find the voices in a conversation and reduce other sounds.
The system has two AI models. One tracks who spoke when and the turn-taking rhythm. The other mutes voices that do not follow the conversation pattern and other background noise. It can identify a conversation partner from two to four seconds of audio and runs on common off‑the‑shelf hardware. The team showed the work in Suzhou and released the code as open‑source.

- background noise — unwanted sounds around that make hearing hard
- open‑source — software with publicly available source code
