Mild cognitive impairment (MCI) is a neurological condition characterized by a noticeable decline in cognitive abilities, including communicative and linguistic skills. In this study, we measured the duration of vowels produced in a reading task by 55 speakers (30 healthy controls and 25 individuals with MCI). The primary results demonstrate that MCI speakers differ significantly from healthy controls (HC) in vowel duration, producing overall longer vowels. Furthermore, we found that gender effects on vowel duration manifest differently between the MCI and HC cohorts. A significant aspect of these findings is that they highlight the potential contribution of acoustic vowel features as diagnostic markers for MCI.
