The use of a voice-user interface for mobile wireless devices has been an area of interest for some time. However, these devices are generally limited by computation, memory, and battery energy, so performing high quality speech recognition on an embedded device is a difficult challenge. This paper investigates the energy consumption of distributed speech recognition (DSR) on the HP Labs SmartBadge IV embedded system and proposes optimizations at both the application and network layers that reduce the overall energy budget for this application while still maintaining adequate quality of service for the end-user.
