Method, device, mobile user apparatus and computer program for controlling an audio system of a vehicle

A method for controlling an audio system of a vehicle including a microphone and a computer, the method comprising:

• capturing with the microphone a voice of an occupant of the vehicle;
• determining, by the computer, in which seat of the vehicle the occupant is sitting based on the voice captured by the microphone;
• changing an audio signal of the vehicle depending on the voice and the seat in which the occupant is sitting;
• predicting a parameter of an auditory communication in an interior of the vehicle;
• and
• changing a parameter of the audio signal of the vehicle depending on the predicted parameter of the auditory communication;
• wherein the changing of the parameter of the audio signal concerns at least one spatial sound parameter, wherein at least one direction from which the audio signal of the vehicle comes or is heard by a driver of the vehicle is adjusted;
• wherein the changing of the parameter of the audio signal includes modifying the audio signal in a frequency range in such a way that signal components of the audio signal relating to the frequency range of human speech within the voice of the occupant are modified in such a way that signal energy is distributed to multiple frequency ranges that do not relate or that relate to a lesser extent to the frequency range of the voice of the occupant;
• and
• wherein the changing of the parameter of the audio signal includes at least partial displacement of frequencies of the audio signal that correspond at least statistically to frequencies of the voice of the occupant, from a first spatial direction in which the occupant is located to a second spatial direction, which is arranged differently from the first spatial direction, essentially opposite to the first direction.
