Outline of Final Research Achievements

The purpose of this study was to develop a noninvasive and simple swallowing frequency measurement system that can automatically discriminate swallowing events during daily life.
Focusing on the physiological phenomenon that respiration stops when swallowing, a waveform recorded simultaneously of laryngeal sound and nostril sound was analyzed. As a result, it was possible to establish a protocol that can identify swallowing events under everyday environmental sounds. However, programming the protocol was difficult, and we could not build an analysis system that could automatically detect swallowing.
We also worked on elucidating the problem of "Which part of the cervical part of the neck can be gathered the optimum swallowing sound" that was derived during the research, and it was possible to summarize the result in the paper.
