Location Based Speaker Segmentation

This paper proposes a technique that segments into speaker turns based on their location, essentially implementing a discrete source tracking system. In many multi-party conversations, such as meetings or teleconferences, the location of participants is re ...

Audio-Visual Speaker Tracking with Importance Particle Filters

Daniel Gatica-Perez, Jean-Marc Odobez, Guillaume Lathoud, Darren Moore

We present a probabilistic methodology for audio-visual (AV) speaker tracking, using an uncalibrated wide-angle camera and a microphone array. The algorithm fuses 2-D object shape and audio information via importance particle filters (I-PFs), allowing for ...

Microphone Array Post-filter based on Noise Field Coherence

Hervé Bourlard

This article introduces a novel technique for estimating the signal power spectral density to be used in the transfer function of a microphone array post-filter. The technique is a generalisation of the existing Zelinski post-filter, which uses the auto- a ...

The enigma of the sphinx

Daniel Thalmann, Olivier Renault, Frédéric Vexo, Tolga Abaci, Mireille Clavien, Jan Ciger

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection sc ...

Segmenting Multiple Concurrent Speakers Using Microphone Arrays

Guillaume Lathoud, Darren Moore

Speaker turn detection is an important task for many speech processing applications. However, accurate segmentation can be hard to achieve if there are multiple concurrent speakers (overlap), as is typically the case in multi-party conversations. In such c ...
