Study finds false positive bias in AI speech-based cognitive screening for UK multilinguals
New arXiv research investigates AI models that detect early signs of dementia and mild cognitive impairment from conversational speech, focusing on multilingual English speakers in the UK. The authors report that such screening tools show a false positive bias, disproportionately flagging multilingual speakers compared with monolingual ones. The findings suggest speech-based cognitive screening may disadvantage linguistically diverse populations unless corrected.
