What’s happening 


  • As part of the Creative Week event Sound Design Institute and SoundDesigner.PRO studio demonstrated the technology Autovoice, — the world's first synthesizer for generative voice-over of an electric car.
  • The system works as follows: when the pedals are pressed, Autovoice generates a sound similar to the sound of a car engine. However, unlike similar systems, sound generation does not occur due to the playback of samples, but sound synthesis. The technology is used in the minimum speed range, as well as when moving backwards.
  • Autovoice is designed to ensure the safety of traffic involving electric vehicles — since an electric motor does not make the sounds characteristic of a car, it is more dangerous on the road.
  • According to representatives of the Sound Design Institute, the technology can be applied to personal cars, electric buses and urban scooters.

What does it mean?


The rapid development of electric transport puts on the agenda the issue of ensuring road traffic with a new "participant" in the transport system. Despite the fact that electric cars are a convenient and eco-friendly way of transportation, an electric motor is much quieter than internal combustion engines, which means it is more dangerous for pedestrians, because they hardly hear the approach of the car.
In this regard, the European Union in 2019 obliged manufacturers of electric cars to equip vehicles with an acoustic vehicle warning system (AVAS), that simulates the sound of a standard internal combustion engine when driving at a speed of less than 20 km/h, as well as reversing. From July 2021, this regulation applies to all electric and hybrid vehicles registered in the EU. Similar measures have also been taken in the USA and a number of other countries.

However, currently there is no single sound generation system for electric cars — each carmaker is trying to create its own unique sound. For example, Mercedes attracted the Linkin Park group to create its "sound".

In the SoundDesigner.PRO studio we hope that the basic rules of sound generation developed by us will become a new standard and help make the movement of electric vehicles safer.
