An Automated Approach to Examining Pausing in the Speech of People With Dementia

American Journal of Alzheimer’s Disease &Other Dementiasr, Volume 35, Issue , January-December 2020.
Dementia is a common neurodegenerative condition involving the deterioration of cognitive and communication skills. Pausing in the speech of people with dementia is a dysfluency that may be used to signal conversational trouble in social interaction. This study aimed to examine the speech-pausing profile within picture description samples from people with dementia and healthy controls (HCs) within the DementiaBank database using the Calpy computational speech processing toolkit. Sixty English-speaking participants between the ages of 53 and 88 years (Mage = 67.43, SD = 8.33; 42 females) were included in the study: 20 participants with mild cognitive impairment, 20 participants with moderate cognitive impairment, and 20 HCs. Quantitative analysis shows a progressive increase in the duration of pausing between HCs, the mild dementia group, and the moderate dementia group, respectively.An Automated Approach to Examining Pausing in the Speech of People With DementiaAn Automated Approach to Examining Pausing in the Speech of People With DementiaAlzheimers{$excerpt:n}
