Seminar by Nicolas Obin on speech prosody

Nicolas Obin, from IRCAM in Paris, will give a talk on "Analysis and Modeling of French Prosody for Artistic Purpose" on Monday March 16th at 13:00h in room 55.410 (4th floor of Tànger building).

Abstract: Over the past decade, voice and speech technologies have received a significant increase of attention in multi-media and artistic applications. In particular recent improvements in speech synthesis make it possible to generate natural speech from text. However if the generated speech sounds "acoustically" natural (coarticulation, phonem level) it could appear unnatural according to the expected "way of speaking" and is most of the time repetitive and boring. This is due to the fact that speech synthesizers did not use to take into account such "way of speaking", i.e. the prosody of speech. Thus prosody has become a main focus in speech research over the past few years. At the acoustic level prosody is related to the macro variations of a set of acoustic parameters of speech (fundamental frequency, local speech rate, intensity, voice quality,...) over time. Such variations are used by a speaker to convey meaning and emotional states. In this talk I am going to present some aspects of my research work on prosody applied to French langage. This work aims to model prosody with high-level linguistic features (syntactical, semantic, discursive) in different speaking styles. I will first introduce some concepts about prosody and linguistic; thus I will present the global framework of prosody modeling. Then I will present some of my work on the analysis of French prosody: syllable-based prominence detection, speaking style analysis and finally introduce my proposed prosodic model based on parametric multi-level context-dependent analysis.  I will also present some aspects of my concerns in the artistic usage of this type of research.

The on-line casting of Operación Triunfo is again powered by BMAT
Aslast year, BMAT, the spin-off company of the MTG, powers the on-line casting of "Operación Triunfo" on its 2009 season. The online casting uses an automatic scoring system of the participant's singing called bluesonic and powered by BMAT skore. This system has been developed by BMAT and it is based on a technology from the MTG.

Carry out your sound project with the help of Sons de Barcelona

The aim of this call is to activate, to promote, and to support works related to the sound sphere of the city of Barcelona and it is addressed to everybody interested in make their projects known. Send your proposal before April 3th to sonsdebarcelona [at] freesound [dot] org

Read the rules.

The MTG started in 2008 the project Sons de Barcelona (Sounds of Barcelona) in order to offer to everybody a database of sounds of this city created in a collaborative way, with the contribution of the citizens themselves and integrated into the international project freesound.org, also from MTG. The sounds are recordings of acoustic environments of Barcelona or different sounds generated in very different ways by the users, and published under Creative Commons License (so they can be freely re-used again). The Sounds of Barcelona team conducts workshops addressed to different collectives in order to propagate the use of audio technologies, to teach how to take advantage of all their possibilities, and to awake an interest towards working with sounds.

Participación en las V Jornadas Imaginática 2009

Emilia Gómez y Jordi Bonada dan una conferencia sobre "Aplicaciones Informáticas para la música: Sistemas de recomendación musical y procesado de voz cantada" en las V Jornadas Imaginática 2009 que tiene lugar en Sevilla del 2 al 6 de Marzo del 2009.

Resumen:  En ésta charla presentaremos una serie de tecnologías para el análisis y el procesado de sonido mediante herramientas informáticas. Nos centraremos el uso de de dichas tecnologías en tres contextos determinados: un sistema de análisis, búsqueda y recomendación de música (http://www.bmat.com/ella), una herramienta de análisis y evaluación de voz cantada (http://www.bmat.com skore) y un sistema de generación de canto a partir del modelado de una voz determinada (http://www.vocaloid.com/).

Seminar by Volker Hohmann on signal processing for hearing aids

Volker Hohmann, from the University of Oldenburg, will give a seminar on "Model-based signal processing for hearing aids" on Thursday February 26 2009 at 3:15pm in room 52.321 of the Communication-Poblenou Campus.

Abstract: The aim of the work presented in this talk is to investigate potential applications of models of human auditory processing to signal processing in hearing aids. Firstly, implications of using nonlinear peripheral auditory models for the design of dynamic compression systems for hearing aids are discussed. In particular, results from a multi-band instantaneous compression scheme are presented, which is based on a novel nonlinear auditory filterbank controlled by the instantaneous frequency calculated in frequency sub-bands. Secondly, a general framework for computational auditory scene analysis (CASA) is introduced and applied to the problem of estimating spatial direction and spectral envelope of super-imposed sound sources from a binaural input signal.

Xavier Serra receives an ICREA Academia Price
Xavier Serra has received a price of the ICREA Academia program offered by the Generalitat de Catalunya. The price is 250.000€ to be used for research activities for the period 2009-2014.

The ICREA Academia program recognizes the research excellence and leadership with the goal to motivate and retain university faculty members from the catalan public universities. ICREA is an institution of the catalan government that has as a fundamental objective to hire researchers from around the world through a selection process based on scientific talent.

Seminar by Johan Sundberg on the singing voice

Johan Sundberg, from the Royal Institute of Technology of Sweden, will give a seminar on "The voice as a music instrument" on Thursday 12th of February at 15:00h in room 52.321 at the Roc Boronat building of the Comunication-Poblenou Campus.

Abstract: By varying the air pressure in the lungs, the length and tension of the vocal folds, the glottal adduction and the shape of the vocal tract the human voice can be continuously varied along three perceptual dimensions: loudness, pitch, and timbre. In this sense the human voice is more flexible than other music instruments. Contributions to timbral variation emanate from both the vibrating vocal folds and from the resonatory properties of the vocal tract. The presentation will review some investigations of how singers use these means for the purpose of vocal economy and musical expressivity.
