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.

input-impedance in phonation
• Laryngeal endoscopie,
high-speed cinematography, glottal edge detection
• Electroglottography
• Voice assessment

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)
