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.
