An exploratory model of speech intelligibility for healthy aging based on phonatory and articulatory measures.

ABSTRACT:

Purpose

The aims of the current study were to determine age-related changes to the phonatory and articulatory subsystems and to investigate an exploratory model of intelligibility for healthy aging based on phonatory and articulatory measures.

Method

Fifteen healthy, older adults (55-81 years) and 15 younger adults (20-35 years) participated in instrumental assessments of the phonatory (aerodynamic, acoustic) and articulatory (kinematic) subsystems. Speech intelligibility was determined by five listeners during multi-talker babble.

Results

Older adults displayed shorter maximum phonation time, greater airflow during sentence reading, and lower cepstral peak prominence (CPP) and CPP SD. Additionally, older adults had slower tongue movement speed than younger adults. Sp
