    The ability for a smart speaker to localize a user based on his/her voice opens the door to many new applications. In this paper, we present a novel system, MAVL, to localize human voice. It consists of three major components: (i) We first develop a novel multi-resolution analysis to estimate the Angle-of-Arrival (AoA) of time-varying low-frequency coherent voice signals coming from multiple propagation paths; (ii) We then automatically estimate the room structure by emitting acoustic signals and developing an improved 3D MUSIC algorithm; (iii) We finally re-trace the paths using the estimated AoA and room structure to localize the voice.more »We implement a prototype system using a single speaker and a uniform circular microphone array. Our results show that it achieves median errors of 1.49o and 3.33o for the top two AoAs estimation and achieves median localization errors of 0.31m in line-of-sight (LoS) cases and 0.47m in non-line-of-sight (NLoS) cases.« less

    Collaborations that require information sharing and mutual trust between companies, suppliers, and clients can be tough, particularly in the remote era. But blockchain’s distributed ledger — and its use of smart contracts — can simplify the process, creating a common, reliable record of transactions and avoiding costly disputes. In doing so, blockchain changes how deals are made: Partner selection is made simpler, as establishing trust is less important; agreement formation is more important, because protocols are hard to alter once put in place; and execution is made easier, because outcomes can be automated. Blockchain isn’t a magic bullet — itmore »works much better in some situations than others — but it can fundamentally change how collaborations work.« less
