EVAS – Embedded Voice Control System

EVAS – embedded voice assistant system

ref: 115-311-001

EVAS is the first embedded voice control system with integrated database communicating in CAN BUS interface. It is multi-speakers, multi-languages, and works off-line.
The system recognizes the order configured by the operator and translates it by sending a CAN frame on the network. EVAS allows you to control the vehicles functions, to activate combinations of functions, or to ask for information by voice, while leaving the operator focused on its main mission

Pre-recorded voice commands are offered during system setup, but it is also possible to record your own commands. It is therefore a 100% customizable system, it can register up to 1000 orders. Its configuration is simple and intuitive.

Therefore, EVAS will bring you safety, productivity and comfort. In addition, its IK08 impact resistance and IP67protection allow it to adapt to all the most severe environments.
