Voice production and perception
My
research projects deal with physiological, phonetical, physical and
perceptual characterization of human voice, and in particular
singing voice. I study glottal vibratory behaviour, the
influence of supraglottal structures (ventricular folds,
semi-occluded vocal tract with a straw),
vocal-tract acoustical resonance tuning, and source-filter
interactions. These research projects are based on developing,
improving and
evaluating experimental methods for measuring physiological and
physical phenomena involved in voice sound production (speech and
singing). They are applied
to the understanding of singing vocal techniques, and to exploring
vocal effort in speech.
Physiological, phonetical, physical and perceptual characterisation of voice production
in speech and singing
1. Voice and Technology
improvement of existing tools, conception
of new tools for measuring and analysing human voice
• Vocal-tract input-impedance in phonation
• Laryngeal endoscopie, high-speed cinematography, glottal edge detection
• Electroglottography
• Voice assessment
2. Voice and Music
Singing-voice characterization among styles and cultures around the world
• Western lyrical singing
• Non-classical singing (jazz, pop, rock, musicals, Beatbox)
• Vocal cultures around the world (Sardinian Bassu singing, Bulgarian female singing)
3. Voice and Modelling
Source-filter interaction, pneumo-phono-resonantial adaptations
• Resonance tuning and vocal-tract acoustics
• Effect of acoustic load on glottal behavior
• Ventricular folds
• Management of subglottal pressure
4. Voice and Health
• Vocal effort, vocal loading and fatigue
• Speech-aid device
• Vocal morbidity following cervical endocrine surgery
• Communicational impact of tinnitus
5. Voice and Language
Phonetic learning of French as a Second Language
