Sound and Music Computing projects:
Technical Vocology

The voice is our primary means of communication: it can transmit not only words, but also a wealth of non-verbal information about its owner. Our role is to further our understanding of the voice, by bridging the gaps between physics, performance and care. Medical diagnosis and assessment of vocal function is a major topic, where we collaborate primarily with the Karolinska Institute. The acoustic signal is only an indirect manifestation of what the vocal folds and the vocal tract are doing, so non-acoustic tools such as imaging and modelling of the voice are also necessary for this work. We also research how the voice is used in the performing arts, such as theatrical speech, and in the various styles of singing such as classical, commercial, folk and choirs.

Active projects:

FonaDyn - Phonatory Dynamics and States
Funding: VR

The voice has several non-linear and context-dependent mechanisms that can give rise to distinct phonatory states. We submit that much of the observed variability in objective voice metrics results from the influence of such states, and will attempt to account for some of them, using a state-based analysis paradigm.

COST2103 - Advanced Voice Function Assessment
Funding: EU, KTH

The main objective of the Action is to combine previously unexploited techniques with new theoretical developments to improve the assessment of voice for as many European languages as possible, while acquiring in parallel data with a view to elaborating better voice production models.

EUNISON - Extensive UNIfied-domain SimulatiON of the human voice
Funding: EU, KTH

This project seeks to build physics-based simulations of the human voice that are more detailed and more complete than before, using numerical models that have been validated against mechanical replicas. The simulations will be accessible for control in the mechanical, neuromotor and phonetic domains. The project engages seven research groups... [more]

Hi-Fi Voice - Hi-Fi Voice: the fine structure of the voice signal at high frequencies
Funding: VR

The human voice has weak but perceptually important frequency components at frequencies above 4-5 kHz. This frequency range is studied from production and perception perspectives. [more]

SingHab - Advanced objective measures of voice in professional female singers
Funding: Fondation Alma et Baxter Ricard, Canada

The long-term goal of this research project is to improve the evaluation of the singing voice in clinical settings. A tailored assessment of the singing voice is crucial to the effectiveness of rehabilitation work. The result of this research will be to provide useful and clinically accessible evaluation possibilities for... [more]

SkAT-VG - Sketching Audio Technologies using Vocalizations and Gestures
Funding: EU

The SkAT-VG project will develop a system that enables sound designers to sketch sounds using their own voice and gestures as input. The project partners are IUAV in Venice (coordinator Davide Rocchesso), IRCAM in Paris, KTH in Stockholm, and the company GENESIS S.A. in Aix-en-Provence. [more]

Song - Sundberg's Voice Science
Funding: KTH CSC - TMH Sundberg

Kulning - Hard rock - Twang - Belting - Chest/Falsetto - Whisper - High pitch singing - Text intelligibility - MRI [more]

SVP Voice - Detailed multiphysics simulation of human voice production with neural control - a feasibility study
Funding: KTH CSC

This project is a feasibility study in which we examine whether it is possible to make a unified-domain numerical simulation of human voice production that covers the mechanical, fluid and acoustic phenomena involved; and also attempts to control the simulation using representations of (simulated) muscle activation.

VoiceMech - Numerical modelling of the non-vibratory biomechanics of human voice production
Funding: VR

In the VoiceMech project, a 3D biomechanical model of the non-acoustic parts of the human voice is in development, mainly to serve as a controlling interface for the aerodynamic/acoustic models that are under construction in the Eunison project. VoiceMech is conducted in collaboration with several others, notably the ArtiSynth project... [more]

VoxLog - VoxLog: portable voice analyzer

A new wearable voice+noise dosimeter has been developed. The project has assessed the validity, usability and commercial potential of the new device. [more]
