Orator 3

Consistent delivery of competitively priced products that are highly reliable and offer excellent speech quality has earned the company an enviable reputation in the elevator industry.

For over 25 years Formula Systems, part of The Airdri Group, has been designing and manufacturing speech units for use in industrial applications such as speech annunciation in elevator cars and escalators. Consistent delivery of competitively priced products that are highly reliable and offer excellent speech quality has earned the company an enviable reputation in the elevator industry.

With major advances in technology taking place every few years, regular updating of the central speech platform is critical. By taking advantage of the latest developments in microcontrollers (MCUs), storage technology and speech compression techniques, Formula Systems can improve speech quality, develop longer message times, lower energy consumption and make it easier to programme new messages.

We have developed our 3rd generation speech platform, Orator 3TM, to do just this. Industrial applications cannot make use of short lived consumer based technologies. The industry demands products with long life-cycles.

This new platform is based on the ARM®Cortex® family of powerful 32-bit MCUs and single level NAND flash. The platform makes extensive use of the latest digital techniques in voltage regulation and audio amplification improving efficiency and reducing energy consumption.

Using an MCU instead of a dedicated consumer (short-lived) speech compression chip, such as an MP3 decoder, provides the flexibility to use whichever compression algorithm offers the best compromise of speech compression (lowest memory usage footprint) and speech quality. This design makes use of MP3 speech compression.

Adopting NAND flash storage means that total message time has been vastly increased. In addition to their own custom messages, customers can make use of Formula Systems extensive library of standard messages and languages to store large numbers of messages in multiple languages in each speech unit.

The Orator 3TM speech platform is designed to be quickly and easily interfaced to a customer specific serial or parallel interface.
