Personalized sound zones technology is a groundbreaking solution for enhancing the travel experience in consumer vehicles. By creating acoustically separated areas within the car interior, this technology allows for novel use cases, such as robust individual interaction with a voice assistant for the driver and simultaneous high-quality private voice calls for passengers.

Personalized sound zones require two components: source separation at voice capture and personalized audio reproduction. This paper focuses on source separation, by analyzing how microphone types and positioning affect the starting conditions for the task and presenting a solution that improves the separation and enhancement performance for any microphone type.
