Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Automatic genre classification of music content

Giorgio Zoia, Nicolas Scaringella

This paper reviews the state-of-the-art in automatic genre classification of music collections through three main paradigms: expert systems, unsupervised classification, and supervised classification. The paper discusses the importance of music genres with ...

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 ...

Parametric coding of spatial audio

Christof Faller

A wide range of techniques for coding a single speech or audio signal channel have been developed over the last few decades. In addition to pure redundancy reduction, sophisticated source and receiver models have been considered for reducing the bitrate. O ...

Delay aspects in Internet telephony

Catherine Boutremans

In this work, we address the transport of high quality voice over the Internet with a particular concern for delays. Transport of interactive audio over IP networks often suffers from packet loss and variations in the network delay (jitter). Forward Error ...

The VidTIMIT Database

This communication describes the multi-modal VidTIMIT database, which can be useful for research involving mono- or multi-modal speech recognition or person authentication. It is comprised of video and corresponding audio recordings of 43 volunteers, recit ...

Adaptive Delay Aware Error Control for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...

Realisation of an Adaptive Audio Tool

Catherine Boutremans, Arnaud Meylan

Real-time audio over the best effort Internet often suffers from packet loss. So far, Forward Error Correction (FEC) seems to be an efficient way to attenuate the impact of loss. Nevertheless to ensure efficiency of FEC, the source rate must be continuousl ...
