AI cognitive screening models show significant bias against multilingual speakers

A new study published on arXiv has identified a significant false-positive bias in AI models used for speech-based cognitive screening, particularly affecting multilingual individuals in the UK. The research found that these models, including Whisper, Wav2Vec 2.0, and NeMo, were approximately 2.5 times more likely to incorrectly label multilingual speakers as cognitively impaired compared to monolingual English speakers. This bias was more pronounced in memory, fluency, and reading tasks and worsened when models were trained on existing datasets like DementiaBank, highlighting a critical need for equitable AI deployment in healthcare.

    False positive bias in AI-powered speech-based cognitive screening for multilingual English speakers in the UK

    arXiv:2602.13047v2 Announce Type: replace Abstract: Conversational speech reveals early signs of cognitive decline, including dementia and mild cognitive impairment (MCI). AI models show promise for speech-based screening, yet most research focuses on monolingual groups. In the U…
