Delay reporting information descriptive of an existing delay of the participant computing device is received from each participant computing device of a participant cohort. The existing delay includes a period of time between transmission of audio data from the teleconference computing system and receipt of the audio data by the participant computing device. The participant cohort includes multiple participant computing devices that are co-located within a same area and are connected to a teleconference hosted by the teleconference computing system. A target delay is determined for the participant cohort. The target delay includes a period of time greater than the existing delay of participant computing devices. The target delay is configured to cause synchronized audio playback when implemented by the devices. Target delay information indicative of the target delay is provided to the participant cohort.
