Characterization of Speech from Amyotrophic Lateral Sclerosis by Neuromorphic Processing

摘要

Amyotrophic Lateral Sclerosis is a severe disease which dramatically reduces the speech communication skills of the patient as illness progresses. The present study is devoted to define accurate and objective estimates to characterize the loss of communication skills, to help in monitoring illness progress, and in rehabilitating speech by specialists. The methodology proposed is based on the perceptual (neuromorphic) definition of speech dynamics, concentrated in vowel sounds in character and duration. A longitudinal study carried out on an ALS patient during a year is shown, its results discussed and conclusions for a further study are also presented.
