Monitoring the health of the phonatory system plays a key role for the voice professionals, which are people who use the voice as a work tool. The voice quality can be assessed by means of parameters extracted from the vocal signal sensed by a contact sensor placed at the base of the neck, that is sensitive to the skin vibration related to the phonation. The use of a contact sensor is preferable to a microphone in air because of its lower sensitivity to the acoustical background noise. This paper focus on the development of a system for the characterization of the contact sensor that can be used for this purpose: an apparatus that can mimic the phonatory system and can act like a standard for testing the sensors. Such a system has been created and preliminary tested and characterized, in order to point out the similarity with the real phonatory system and to bring out any critical issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
