Accelerated Speech Source Localization via a Hierarchical Search of Steered Response Power

D.N. Zotkin, R. Duraiswami
2004 IEEE Transactions on Speech and Audio Processing  
We present applications of the search algorithm to speed up simple delay-and-sum beamforming and steered response power phase-transform weighted (SRP-PHAT) source localization algorithms.  ...  Recently, approaches that are based on search for local peaks of the steered response power are becoming popular, despite their known computational expense.  ...  CONCLUSIONS We have presented a generic doubly hierarchical search algorithm for speech source localization using steered response power.  ...

Contextual push-to-talk

Garrett Weinberg, Bret Harsham, Clifton Forlines, Zeljko Medenica
2010 Proceedings of the 12th international conference on Human computer interaction with mobile devices and services - MobileHCI '10  
We present a driving simulator-based evaluation of a new technique for simplifying in-vehicle device interactions and thereby improving driver safety.  ...  We show that the use of multiple, contextually linked push-to-talk buttons (Multi-PTT) shortens voice dialog duration versus the use of a conventional, single push-to-talk button (Single-PTT).  ...  Content Indexing and Searching In addition to browsing via the hierarchical menus described above, users may find items using short spoken queries [29] .  ...
