KTH-TMH

Main tasks: EUNISON project coordinator, laryngeal and vocal tract topologies, control architecture.

TMH, the Department of Speech, Music and Hearing is an internationally recognised centre for speech communication and voice science (www.speech.kth.se). Originally founded in 1961 by the late Gunnar Fant, the department is now well into its third generation of about 30 researchers. Current research topics include man-machine dialogue systems, robotic applications of speech technology, and analysis and modeling of voice production in speech and singing. The TMH department has decades of work experience in speech synthesis and speech recognition, voice analysis and synthesis. KTH-TMH has participated in numerous EU projects.

KTH-HPCViz

Main tasks: Development of a fluid-structure interaction model of the larynx.

The Computational Technology Laboratory is a research group of about ten researchers at the intersection of mathematics and computer science, with focus on the development of computational methods and software for high performance simulation of complex systems in different areas, including aerodynamics and aeroacoustics, biomedicine and geophysics. The group is a main developer of the international open source software project FEniCS, with in particular the DOLFIN/Unicorn finite element software to be used in the project.

KTH-CB

Main task in EUNISON: Tissue biomechanics, modelling neural motor control.

The department of Computational Biology is at the international forefront of developing and using computational methods for analysing and mimicking biological systems. The main focus is on understanding the nervous system, from membrane currents through ion channels, via electrophysiological properties of neurons to information processing in neuronal networks. While firmly rooted in computer science and engineering physics, the department houses experts ranging from bioinformatics and neuroscience to statistical physics and biomechanical control. The department of Computational Biology has been doing pioneering work on coupling neural and biomechanical models (from 1993). This has given extensive experience of model- ling passive and active tissue, including muscles and tendons, primarily for studying walking and swimming in animals.

La Salle

Main tasks: Scientific coordination, and vocal tract acoustics simulations, unified approaches and dissemination.

The Universitat Ramon Llull (URL), located in Barcelona, Spain, is a non-profit making federated private entity. It integrates 10 centres, each with its own legal identity, and a wide trajectory in research and higher education. Within URL, La Salle School of Engineering is responsible for performing research and education in the technical domain. The Research Group for Media Technologies (GTM) from La Salle is accredited as a consolidated group by the autonomous government of Catalonia. It is a multidisciplinary research environment focused on innovation in new multimedia technologies. The knowledge areas that converge in the GTM are: multimodal signal processing with special emphasis on speech, acoustics, digital television, multimedia (graphics, virtual reality, animation), usability and user experience analysis.

FAU

Main tasks: Experiments on vocal fold replicas, study of energy transfer mechanisms.

The Institute of Process Machinery and System Engineering (iPAT) is part of the Department for Chemical and Biological Engineering (CBI) of the Technical Faculty of the University Erlangen, Nuremberg (FAU). The activities of the institute include applied research, industrial contract research as well as fundamental investigations. The research objectives of the group of Fluid System Dynamics and Aeroacoustics are focused on biomechanical flows, turbomachines, cooling systems, car acoustics and pipe flows. One of their major basic research topics states processes involving fluid-structure-acoustic interactions. For the past eight years, the group has been working intensively in the field of experimental investigation of in-vitro vocal fold oscillations using synthetic models.

CIMNE

Main task: Development of compressible code for computational fluid dynamics; and grand unification (mechanical+flow+acoustics).

The International Centre for Numerical Methods in Engineering (CIMNE) is a research organization based in Barcelona, Spain. CIMNE was created in 1987 as a Consortium between the Catalan government and the Universitat Politecnica de Catalunya (UPC). CIMNE employs some 180 scientists and engineers from different technical fields and nationalities in the development of numerical methods (basically the finite element method) to a wide class of engineering problems. The research activities of CIMNE cover non linear analysis and safety studies of structures, shape optimisation in structural and fluid dynamic problems, computational fluid dynamics studies for both external and internal flow problems and numerical simulation of material deformation and forming processes for the casting and sheet stamping manufacturing industry, mesh generation and visualization interfaces, stochastic optimisation as well as computing techniques.

CNRS

Main tasks: Modelling and measurement of articulation in replicas, dynamic aspects of voice production physics.

The Department Parole et Cognition of GIPSA-Lab (UMR INPG, CNRS, Universite Stendhal, Université Joseph Fourier) at Grenoble, formerly the Institut de la Communication Parlee, gathers researchers and specialists from physics to signal and data processing, phonetics, neurosciences, and cognitive psychology. The GAMA team has gained a long experience in aeroacoustical modeling (theoretical and experimental) of the vocal folds, as well as physiological investigation of phonation in both speech and singing. In order to validate flow models with different degrees of complexity, the lab offers experimental setups and mechanical replicas, rigid as well as deformable, suitable to reproduce flow conditions relevant to the upper airways; and relevant physical quantities can be measured. Two sound- insulated rooms are shared with the Department, and three specific experimental rooms are devoted to these experimental studies which also include flow visualization. Lastly, the team has access to the mechanics workshop of the Gipsa-lab to design and build mechanical replicas.

Key personel: Directeur de recherche Xavier Pelorson.
