This publication describes methods for coordinated listening by multiple voice assistant devices (e.g., smart home devices, smart speakers) to localize the sound of a low-battery warning chirp produced by a smoke detector. The voice assistant devices detect the sound of the low-battery warning chirp and measure the volume and timing of the chirp (generate “chirp information”). The chirp information can be provided to a processing unit of a computing device that estimates a location of the smoke detector and provides such information to a user.
