A peripheral device (e.g., a small wearable device) may operate in conjunction with a camera to enable in-the-moment capture and control. The peripheral device may receive voice commands and uses voice recognition to generate a control signal to control the camera, thereby enabling users to freely participate in their activities while seamlessly controlling the camera in a hands-free manner. Additionally, the peripheral device may operate as a wireless microphone source to capture high quality audio for instead of or in addition to audio captured by the camera. This may provide improved audio quality in certain operating conditions such as during narrating and interviewing.
