Accelerometer Based Measurement For The Mapping Of Neck Surface Vibrations During Vocalized Speech, Mark Nolan, Brian Madden, Edward Burke

Conference Papers

This paper presents a detailed study of the vibrations on the surface of the neck during a vocalization of predefined fundamental frequency and intensity. This study was carried out as part of a wider investigation into the use of laryngeal vibrations as a channel of communication. Another potential application of this study is in identifying a suitable location for a hands-free electro-larynx for laryngectomees.

An analog accelerometer, with dimensions 5x5x1.6mm and of mass 80mg, was used to perform the measurements. It was connected to a 12-bit analog-to-digital converter via single strands of insulated wire with a diameter of 100μm. The …
