Passenger Information System : Voice Announcement (Speaker)

The Voice announcement System comprises of Amplifiers and speaker units. These are mounted inside the bus for next bus stop & destination announcements meant for passengers inside and outside the bus. There are two independent audio inputs. The audio signal for these is delivered by the Controller unit by text to voice conversion.

The Controller unit drives the integrated voice announcement System - both inside & outside the bus. The controller unit has two independent audio output ports. The audio output signals from these ports are given to the amplifiers for driving the Speakers.

The Controller unit also maintains a database of announcement messages. It outputs suitable announcement message to the respective speakers at requisite time for making the announcement. The Audio output is transmitted to various speakers mounted inside and outside the bus on two independent channels – one for speakers mounted on external display boards and other mounted inside the bus.
