Paper: Blind Speaker Counting in Highly Reverberant Environments by Clustering Coherence Features

Using only two microphones, like those commonly found on mobile devices, we show in this work how to count the number of people talking in a meeting scenario. This paper has been accepted for publication and presentation at the 2017 Asia Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC) in Kuala Lumpur, Malaysia.

Paper: Towards Real-Time Source Counting by Estimation of Coherent-to-Diffuse Ratios from Ad-Hoc Microphone Array Recordings

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.

The Conversation

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
