This paper firstly reports on the design of an audiovisual ‘face cover’ corpus. High-quality audio and video recordings were taken of 10 speakers reading phonetically-controlled stimuli under various face disguise conditions. Possible articulatory, acoustic and perceptual effects of the masks in a forensic context are introduced. Secondly, preliminary results of a spectral analysis of voiceless...

This paper presents an automatic music selection system based on runner’s step frequency. Recent development of portable music players like iPod has increased the number of those who listen to music while exercising. However, few systems which connect exercises with music selection have been developed. We propose a system that automatically selects music suitable for user’s running exercises. A...

In this paper, we describe a new method submitted to Mirex 2007 multiple fundamental frequency estimation contest.

A methodology is proposed for non-parametric density estimation, constrained by the known expected values of one or more functions. In particular, prescribing the first moment –the mean of the distribution– is a requirement for the density estimation associated to martingales. The problem is addressed through the introduction of a family of maps that transform the unknown density into an isotro...

Using a wah-wah pedal guitar is something guitar players have to learn. Recently, more intuitive ways to control such effect have been proposed. In this direction, the Wahwactor system controls a wah-wah transformation in real-time using the guitar player's voice, more precisely, using the performer [wa-wa] utterances. To come up with this system, different vocal features derived from spectral ...

Main techniques of probability density estimation on Riemannian manifolds are reviewed in the hyperbolic case. For computational reasons we chose to focus on the kernel density estimation and we provide the expression of Pelletier estimator on hyperbolic space. The method is applied to density estimation of re ection coe cients from radar observations.
