Energy aware distributed speech recognition for wireless mobile devices


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. In this paper, we investigate the energy consumption of distributed speech recognition on the HP Labs SmartBadge IV embedded system and propose 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. We consider energy consumption in both computation and communication.
