Blindly counting the number of speech sources (talkers) in a meeting room can be a difficult task. This paper was presented at HSCMA 2017 at the Google Offices in San Francisco and shows how using coherent-to-diffuse ratios could allow real-time source counting.
A hybrid loudspeaker system consisting of dynamic point sources and parametric loudspeaker models shows great results above, generally inevitable, soundfield aliasing frequencies.
This work was presented at APSIPA ASC 2016 in Jeju, Korea.
Picture your typical busy cafe or restaurant that’s full of people. The diners are usually all forced to listen to the same music that’s pumped into the venue via the speakers.
What if you could create sound that was tailored to each table’s taste so the people there could listen to their own music, sports event, news or just enjoy the silence?
It might sound impossible but it’s closer to becoming a reality than you think. Continue reading How to create sounds that only you can hear in a venue
Presented at ICASSP 2016, we explore ways to improve speech privacy in multizone soundfield reproductions using intelligibility metrics, all while maintaining high speech quality.
Recent work on perceptual soundfield reproduction for multizone soundfield cases was presented in Hong Kong at the Asia-Pacific Signal & Information Processing Association Annual Summit and Conference (APSIPA ASC).
