Sound source localization strategies can be traced back to radar and sonar localization systems. In the report, we will review the main challenges of sound source, especially talker, localization problem and current major strategies. We proposed a practical peak-weighted PHAT TDOA method to find reliable source location in the Awarehome, which is a residential lab in Georgia Tech. Finally, we suggest the application scenarios in domestic environment and provide future direction of our work.

Recent research in ubiquitous computing has focused both on how to infer human activity from a variety of signals sensed in the environment as well as how to use that information to support interactions. In this paper, we examine the feasibility and usefulness of sound source localization (SSL) in a home environment, which is an implicit location system to support monitoring of a remote space as well as to infer key activities, such as face-to-face conversations. We present a microphone array system that covers a significant portion of the public space in a realistic home setting and discuss monitoring and automated inferring applications that are made possible with this technology in a domestic setting.
