The voice assistant "Hey Mercedes" is even more learn- and dialogue-capable by activation of online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword
"Hey Mercedes". These include accepting a telephone call. "Hey Mercedes" now also explains vehicle functions. In the S-Class the voice assistant can also be controlled from the rear.
"Hey Mercedes" now supports 27 languages with natural language understanding (NLU). This makes natural interaction on a wide range of topics possible. As a new feature, a completed dialogue can be continued with further commands. Several consecutive instructions can be issued, for example activation of the seat heating and starting the route guidance in the navigation system.
The activation keyword "Hey Mercedes" is no longer necessary for certain applications. An incoming call can be taken directly with "Accept call", for example.
In the S-Class, "Hey Mercedes" can also be controlled from the rear. Several microphones help to tell the system which seat the voice is coming from. The active ambient lighting flashes at this position and identifies the current speaker.
"Hey Mercedes" now also explains vehicle functions, and can e.g. help when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found. The new Chit-Chat and knowledge domain provides the right answers to many questions, and even questions about buildings in the immediate vicinity, animal noises or general knowledge are answered.
"Hey Mercedes" is now also able to recognise vehicle occupants by their voices. Once the individual characteristics of the voice have been learned, this can be used to activate a profile. This makes personal data and functions accessible to the user. Voice recognition is in real time, using a special authentication process.
