A team from Isobar, representing Coca-Cola Sweden, have hit on a cool idea to get people to experiment with Swedish dialects and it uses a Raspberry Pi. The Dialekt-o-maten is situated on a busy high street in Stockholm and challenges visitors to pronounce words in obscure Swedish dialects of which, being a very long country, there are several. If the pronunciation was correct, visitors were rewarded with a Coca-Cola bottle of their choice. The team had to experiment with different filters to block out the noise from surrounding traffic and other people just passing by. The system was originally created on a Mac laptop but was then transferred to a Raspberry Pi. See a promotional video below:
