Scientists at University College London's Institute of Neurology have developed a new tool based on AI language models that can characterize subtle features in the speech of schizophrenia patients. The research aims to understand how automated language analysis can improve the diagnosis and assessment of mental disorders. The study found that the language performance of schizophrenia patients was less predictable by AI models compared to the control group, which may relate to brain learning and cognitive mapping. Scientists plan to widely apply this technology, potentially leading to breakthroughs in the diagnosis of mental illness in the future.
