Like a lighthouse providing early warning in the dark of night, changes in language can signal cognitive decline decades before symptoms of dementia become apparent. Currently, over 47.5 million individuals in the world have dementia, and that number is expected to triple by 2050. At Winterlight Labs, we build technology that can quickly and accurately detect signs of cognitive impairment from a sample of speech. A short 1-5 minute snippet of speech can paint a picture about the speaker's cognitive state, including lexical diversity, syntactic complexity, semantic content, and acoustics. The technology can detect the presence of Alzheimer's disease with 82% accuracy and aphasia with 100% accuracy. Our software is based on years of experience and academic, peer-reviewed research. Our team continues to actively publish in computer science and neuroscience journals and conferences.
