Using virtual acoustics and electroglottography to study the adaptation of singing voice production

Résumé

Previous research has showed that singers and instrumentalist musicians tend to adapt their sound production to theacoustics of the venue in which they perform. Studying such an adaptation process is not trivial since many parametersare to be taken into account. For example, various performances can dier due to aspects of the halls other than acoustic,the interaction with the audience, or the physical and psychological state of the performer. A specific methodology hasbeen used to study how singers vary their sound production when they perform in dierent acoustical spaces withina short period of time. Virtual concert halls were proposed to four singers who could hear themselves in reverberantsound fields by means of a real-time convolution process and dynamic binaural synthesis. The signals captured bya microphone in near-field and by an electroglottography unit were analysed and yielded several parameters relatedto voice production, namely vocal intensity, fundamental frequency, and glottal contact quotient. These voice-qualityparameters were compared to room acoustical parameters from the eight dierent rooms proposed to the singers. Resultsshowed that the singers reacted in specific manners by varying their voice quality and being sensitive to dierent roomacoustical parameters.
