Microsoft Teams has launched new AI-driven features: decorative backgrounds and voice isolation. The decorative background feature is similar to augmented reality filters, allowing users to clean up and replace backgrounds during video calls. The voice isolation feature selectively captures the user's voice during unscheduled calls and meetings. Microsoft is also enhancing Copilot to provide a transcription-free meeting feature and a message writing assistant. These features aim to improve the user experience and collaboration efficiency in Teams.
