Seminar by Fernando Villavicencio on voice transformation applied to singing voice
14 Nov 2014

Fernando Villavicencio, from National Institute of Informatics in Japan, gives a seminar titled "Some applications of Voice-Transformation to Singing-Voice" on Friday November 14th at 12:00h in room 52.s31.

Abstract:
Voice Conversion aims to the transformation of a “source” speaker in order to make it perceptually identifiable as a particular “target” one. Although the main work done in this field has been focused in spoken voice there are potential application for singing-voice synthesis (e.g. for singer’s database conversion on singing synthesis systems).

In this talk we will present previous work applying Voice-Conversion and related Voice-Transformation experimentation to Yamaha’s singing-voice synthesizer “VOCALOID”. The works include singer’s identity conversion by means of statistical timbre-features mapping (GMM) and accurate spectral envelope modelling. Also, aiming for large vocal-quality control from modal (normal) singing, experimentation for voice-quality transformation by source/filter estimation & transformation will be presented. The talk will include an introduction of the National Institute of Informatics and the Sound Media Group.

Biography:
Born in 1977 in Guadalajara, Mexico. Fernando Villavicencio received the Bachelor degree in Electronics and Communications Engineering by the Autonomous University of Guadalajara (1999) and Master degrees in Telecommunications (2002) and Signal Processing & Digital Design (2003) by the National Polytechnic Institute of Mexico and Rennes I University in France respectively. He received the Doctor degree at Pierre and Marie Curie University of Paris following his research work in High-Quality Voice Conversion at the Institute of Research and Acoustic-Music Coordination (IRCAM) under the supervision of Xavier Rodet and Axel Röbel.

F. Villavicencio joined the Music Technology Group of Pompeu Fabra University (2008-2009) to work on singing-voice transformation within a collaboration with Yamaha Corporation. From 2009 to September 2014 was member of the Speech Technology Group of Yamaha’s Sound Technology R&D center in Hamamatsu, Japan. He is currently post-doctoral fellow at the Sound Media Group of the National Institute of Informatics in Tokyo, Japan. His research interests include general topics on speech synthesis, voice transformation, and speaker verification.

Participation to III Jornadas AEOS - Fundación BBVA

Julio Carabias, Emilia Gómez and Alba B. Rosado participate to the 'III Jornadas AEOS - Fundacion BBVA' which will take place on Nov 12-13th 2014 in Madrid. Emília Gomez, its Principal Investigator, is presenting the PHENICX project, including a recently released prototype which integrates a number of technologies provided by partners and some demonstrators based in the repovizz repository for multimodal data.

Part of this conference will be devoted to take a close look at the digital strategies and tools that can help orchestras project themselves more successfully towards the rest of the world and achieve more active communication with their current and future audiences, both on site and on line.

Acte de presentació: Diccionari de les tecnologies del so i de la música
24 Oct 2014

El proper divendres, 24 d’octubre, a les 11 h, a la Sala de Graus de l’Edifici Tànger (55.309) del Campus de la Comunicació-Poblenou de la Universitat Pompeu Fabra, es presentarà el Diccionari de les tecnologies del so i de la música que aplega prop de 250 registres semàntics relacionats amb el llenguatge especialitzat d’aquest àmbit tecnològic. Intervindran en l’acte Enric Peig, Director de l'Escola Superior Politècnica (ESUP) de la UPF, Cristina Bofill, de l’Àrea d'Enginyeries i Tecnologia de TERMCAT i Emilia Gómez, Professora del DTIC-ESUP i membre del Grup de recerca en tecnología musical (MTG) de la UPF.

L'objectiu d'aquest acte de presentació és tractar temes relatius a la importància i problemàtica al voltant dels diccionaris tecnològics i específics en català, la política de multilingüisme de l'ESUP dins dels Graus en Enginyeria i el procés seguit per la creació del Diccionari de les tecnologies del so i de la música.

Aquest és un diccionari elaborat pel Grup de recerca en Tecnologia Musical del Departament de Tecnologies de la Informació i les Comunicacions i l'Escola Superior Politècnica de la Universitat Pompeu Fabra, i coordinat per Emilia Gómez i Felipe Luis Navarro. El diccionari té com objectiu recollir els termes específics acceptats i emprats dins del camp de tecnologies del so i de la música que necessiten conèixer estudiants i professionals de l’àmbit. A més d’incloure termes que designen conceptes generals, també comprèn d’altres més específics relacionats amb l'anàlisi i síntesi de so, acústica, psicoacústica, efectes digitals, dispositius i maquinari.

El diccionari conté 247 fitxes terminològiques amb denominacions en català, castellà i anglès i la corresponent definició en català. En algunes fitxes, al costat de la denominació que és un manlleu no adaptat s’indica entre claudàtors la llengua de procedència del terme per a advertir que la pronúncia habitual del mot no segueix les regles fonètiques del català, sinó les de la llengua assenyalada. Alguns d’aquests manlleus no adaptats estan pendents d’estudi per part del Consell Supervisor del TERMCAT

El projecte ha rebut el suport de diferents entitats involucrades en el desenvolupament i la integració de la terminologia catalana en els sectors especialitzats i en la societat en general. El TERMCAT i el Gabinet Lingüístic de la Universitat Pompeu Fabra han aportat assessorament metodològic i documental, i el desenvolupament del projecte ha estat cofinançat pel Centre per a la Qualitat i la Innovació Docent (CQUID) a través del Pla d'Ajuts de Suport a la Qualitat i a la Innovació Docent (plaQUID) 2012-2013. Addicionalment, també han participat en el projecte investigadors del Grup de Recerca en Tecnologia Musical i del Departament de Sonologia de la Escola Superior de Música de Catalunya.

Galata Electroacoustic Orchestra at La Biennale di Venezia 2014

Last year the MTG participated on the project Galata Electroacoustic Orchestra (GEO), European Erasmus Intensive Programme, and as a result of the project a big orchestra was created with members of 5 institutions from different countries.

This year the orchestra has successfully performed again at La Biennale di Venezia on October 5th.  The orchestra used traditional instruments and laptops, under de conduction of Roberto Doati and Tolga Tüzun.  The members of the orchestra representing the MTG were: Robert Clouth, Nadine Kroher, Rubén Martínez Orio, Felipe L. Navarro, Álvaro Sarasúa (PhD students, former SMC master and ESMUC students).

IRMAS: A Dataset for Instrument Recognition in Musical Audio Signals

We are glad to announce the release of a dataset for Instrument Recognition in Musical Audio Signals (IRMAS dataset).

This dataset was used in the evaluation of the article:
Bosch, J. J., Janer, J., Fuhrmann, F., & Herrera, P. “A Comparison of Sound Segregation Techniques for Predominant Instrument Recognition in Musical Audio Signals”, in Proc. ISMIR (pp. 559-564), 2012

IRMAS is intended to be used for training and testing automatic instrument recognition methods, in a varied set of professionally produced western music recordings. The dataset includes a total of 6705 excerpts for training, and 2874 excerpts for testing. The instruments considered are: cello, clarinet, flute, acoustic guitar, electric guitar, organ, piano, saxophone, trumpet, violin, and human singing voice.

Further information about the music collection, and how the samples were created and annotated is available on the dataset website, where you can also download the audio excerpts and metadata. Given the size of the collection (over 10Gb), you can also first download a sample of the testing and training data, to see if it fits your needs.

We hope that IRMAS will be useful to our scientific community, and we would be very interested in receiving your feedback.
