Analysis of Speech of Older Adults that Focuses on the Parts of Speech and Repetition in Coimagination Method

Abstract

We analyzed the parts of speech, repeated noun and clause from the speech of older adults in Coimagination Method, and examined correlation between cognitive function and linguistic features. Japanese version of MoCA (Montreal Cognitive Assessment) was used for cognitive function assessment of 18 older adults. Repetition clause rate in the sentences increased with the decrease of MoCA score in Coimagination Method. Correlation was not found for the frequency of fillers and other index of repetition rate in the experiment.
