Speech in Alzheimer's Disease: Can Temporal and Acoustic Parameters Discriminate Dementia?

Abstract: Aims: The study explores how speech measures may be linked to language profiles in participants with Alzheimer's disease (AD) and how these profiles could distinguish AD from changes associated with normal aging. Methods: We analysed simple sentences spoken by older adults with and without AD. Spectrographic analysis of temporal and acoustic characteristics was carried out using the Praat software. Results: We found that measures of speech, such as variations in the percentage of voice breaks, number of period… Show more

“…The current definition provided by the World Health Organisation (WHO) describes "dementia" as a syndrome -Tadeusz Paweł Wasilewski, Hanna Kachaniuk usually of a chronic or progressive nature -in which there is deterioration in the higher cortical functions, such as memory, thinking, orientation, calculation, learning capacity, language, and judgement. The impairment of cognitive function is commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour, or motivation Grossberg 2009a, 2009b;Meilán et al 2014). …”

“…Moreover, they tend to have problems with word choice, and their utterances become "bizarre" and devoid of content (Boye et From the logopaedic point of view, it needs to be borne in mind that the situation of Alzheimer's patients is very difficult when it comes to their communication problems. Indeed, in this group, speech problems affect people who have previously mastered a linguistic system and achieved full communicative (social, situational and pragmatic) competence (Grabias and Kurkowski 2012; Meilán et al 2014).…”

“…Pause frequency has been identified as a feature differentiating spontaneous speech in patients with AD from control groups (Gayraud et al, 2011), and may also be used to distinguish between mild, moderate and severe AD (Hoffman et al, 2010). Meilán et al (2014) used AD subjects and spoken data (read loud and clear sentences on a screen). They used acoustic measures such as pitch, volume and spectral noise measures.…”
