Start-ups are promising that they can detect diseases through voice analysis with artificial intelligence. Holger Fröhlich, AI and data specialist, explains why it doesn't work that easily - but that the technology could work more objectively than doctors.

He is currently leading a federally funded project in which he is investigating whether AI can recognize the symptoms of Parkinson's just as well as a neurologist - and whether the technology can correctly record the course of the disease. “To my knowledge, there are currently no AI-based tools that can reliably distinguish all conceivable diseases from all conceivable language changes,” he says.
