Direction-of-Voice (DoV) Estimation for Intuitive Speech Interaction with Smart Devices Ecosystems

Future homes and offices will feature increasingly dense ecosystems of IoT devices, such as smart lighting, speakers, and domestic appliances. Voice input is a natural candidate for interacting with out-of-reach and often small devices that lack full-sized physical interfaces. However, at present, voice agents generally require wake-words and device names in order to specify the target of a spoken command (e.g., “Hey Alexa, kitchen lights to full brightness”). In this research, we explore whether speech alo
