The invention relates to a method for operating a sound output device of a motor vehicle. A voice-analysis and control device receives a voice signal from a voice detection device of the motor vehicle, wherein the received voice signal describes a voice message from a person who is in exterior surroundings of the motor vehicle. The voice signal is used to ascertain a voice message content of the voice message and a thematic context of the voice message. On the basis of that, a voice output signal is provided that describes a context-related response text for the captured voice message, and the provided voice output signal is transmitted to the sound output device to output the provided voice output signal to the exterior surroundings of the motor vehicle.
