Description: Learn about a new technology that analyzes a person’s natural speech to detect and monitor Alzheimer’s disease and other cognitive disorders. The tablet-based assessment tool records short samples of a person’s speech as they describe a picture on the screen and extracts hundreds of variables from the samples.
Because of word-finding difficulties, people with Alzheimer’s disease will tend to pause more between words and the complexity of their vocabulary is reduced. The technology uses artificial intelligence to analyze about 400 variables, such as pitch, tone, prosody (rhythm), and rate of speech, as well as pauses and choice of words. In the laboratory, the software can reliably identify Alzheimer’s disease, Parkinson’s disease, and aphasia with between 85% and 100% accuracy.
