Which company is collaborating on using AI to identify patterns in human speech for predicting Alzheimer's?

The collaboration between IBM and research institutions focuses on utilizing artificial intelligence to analyze human speech patterns as a means for predicting Alzheimer's disease. This effort fits within a broader trend of applying advanced data analytics and AI techniques to enhance early detection and diagnostics in healthcare. IBM has been at the forefront of developing cognitive computing technologies, which can analyze vast amounts of unstructured data, such as voice recordings, to find subtle indicators of cognitive decline. By identifying changes in speech patterns, researchers aim to create innovative tools that may facilitate earlier interventions for patients at risk of developing Alzheimer's.

In contrast, while other companies like Microsoft, Google, and Intel also engage in AI and healthcare-related projects, their specific collaborations focusing on predictive analysis through speech for Alzheimer's are not as established or evidenced in current research as that of IBM's endeavors. This context helps clarify why the correct answer points to IBM in this scenario.
