Systems, methods, and graphical user interfaces for using spatialized audio during communication sessions

An electronic device communicates with a display, an input device, and a wearable audio output device. The device displays a user interface with dynamic visual representations of participants in a communication session. Outputting, via the wearable audio output device, audio from the plurality of participants in the communication session. The audio is adjusted to maintain simulated spatial locations of participants relative to a frame of reference of the communication session, independently of a position of the wearable audio output device relative to the frame of reference. The simulated spatial locations correspond to the locations of the dynamic visual representations. Receiving an input selecting one of the dynamic visual representations. In response, displaying the dynamic visual representations at locations different from their initial locations, and outputting audio from the participants to position their audio at a different simulated spatial locations, relative to the frame of reference.
