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 ...

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 ...

Clustering And Segmenting Speakers And Their Locations In Meetings

Guillaume Lathoud, Jitendra Ajmera

This paper presents a new approach toward automatic annotation of meetings in terms of speaker identities and their locations. This is achieved by segmenting the audio recordings using two independent sources of information : magnitude spectrum analysis an ...

Location Based Speaker Segmentation

Guillaume Lathoud

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 ...

Synthetic vision and audition for digital actors

Daniel Thalmann

We present an overview of some principles of synthetic vision and audition for digital autonomous actors in virtual worlds. After a short review of the state of the art we focus on some aspects of synthetic vision and virtual world constraints. Then we pre ...
