The Road Traffic Office of the Canton of Aargau receives approx. 300’000 telephone inquiries per year, which it is unable to handle quickly and at any time due to limited resources. Outside of office hours, an answering machine provides only limited information. Reduced availability puts pressure on customer satisfaction, which in turn puts a strain on employees. Therefore, the Road Traffic Office decided to deploy a voicebot that can handle the most frequent cases and automatically answer 20–25% of the calls, including Swiss German ones.
