Presenting Sense of Loud Vocalization Using Vibratory Stimuli to the Larynx and Auditory Stimuli
summary
System presents 80 dB /a/ audio through headphones synchronized with neck vibrators with recorded vocal-cord signals to make quiet phonation feel loud. A prototype GUI times 4-second vocalizations and runs 10 conditions (5 vibration intensities × 2 vocal effort) with 15 participants. Results show increased sense of loudness and exhilaration with stronger vibration but excessive intensity produces discomfort and masks vocal intent, so an intermediate vibration level works best.
