Voice AI for Automotive UX
In collaboration with Hume, a Fortune 100 automotive company conducted a study to explore how drivers interact with emotionally intelligent AI in vehicles. Using Hume’s Empathic Voice Interface (EVI), the study aimed to understand how an AI that responds to users’ emotions could create richer, more personalized driving experiences. Over four weeks, a diverse group of drivers engaged with EVI while driving. They asked for directions, checked the weather, and even discussed fun facts. By the end of the study, it became clear that drivers preferred voice assistants with more personality over those focused solely on utility.
