Detection of Cognitive Disorders Using ASR-Based Nonsense Words Repetition

August 22, 2025

Short speech tasks can reveal cognitive changes without requiring a long clinical interview. This paper examines whether automatic speech recognition can evaluate immediate repetition of nonsense words and distinguish healthy participants from people with cognitive impairment. The experiment shows why recognition errors, phonological similarity and the choice of language model all matter when speech technology becomes part of a screening method.

Automatic Cognitive Disorder Detection through Semantic Analysis of Verbal Image Descriptions

August 22, 2025

A spoken image description contains information about more than pronunciation: it also shows which concepts and relations a person notices and how they organise them in language. This paper combines speech recognition, formal semantic analysis and machine learning to compare Czech descriptions with an expert reference. The resulting semantic features offer an interpretable route towards scalable screening for cognitive disorders.
