Thanks to the use of pioneering AI speech synthesis technology from Klangerfinder GmbH & Co KG and S12 GmbH, the Kärcher RCV vacuum robots now speak crystal clear and pleasantly in an incredible 13 languages.

Czech, Portuguese or Turkish… all of the 13 languages have an individual, customized Kärcher AI voice. Whether the battery needs to be charged or the cleaning process has been successfully completed – all relevant information is transmitted clearly via Native AI Voice. In order to achieve the best possible audio quality, all voices were specially optimized in the Masterington studio to the specifications of the small built-in speaker in the Kärcher robot.

“We are delighted to have successfully launched this innovative project together with Kärcher! It is probably one of the most ambitious AI voice projects in the high-end brand sector at the moment. I am particularly fascinated by the quality of the AI voices, which was unimaginable just a few months ago and which almost turn the RCV 3 and RCV 5 into small, likeable personalities. It was also exciting to evaluate in which situations speech is helpful and in which a sound or silence might communicate the message better.”
– Prof. Florian Käppler, CEO sound inventor

The RCV appliances are outstanding cleaning talents that impress with an increased level of user-friendliness!

P.S. The appliances in the RCV range are in the process of learning even more languages – and with the RCF 3 mopping robot, another model with the new voice technology was launched in November 2023.
