Interactive Navigation System

Interactive Navigation Systems offer convenience and enhanced safety by responding to voice commands from the driver and providing audible turn by turn directions.

Accurate voice recognition is critical to the performance of these systems. A dedicated system outside of the Head Unit SOC is an effective way to ensure reliable voice recognition. Cirrus Logic offers a variety of MEMS microphones, ADCs, and DACs to enable high-performance interactive navigation systems.
