Method for operating a voice-control system, in which - a voice input with at least two instructions having an input sequence is detected, wherein a start and an end of the voice input is signaled to the voice-control system by the user or is automatically recognized by the voice-control system, and wherein the at least two instructions are input into the voice input such that several instructions are combined, - a machine-readable text from audio data of the voice input is generated, - a semantic analysis of the machine-readable text is carried out, - then, at least two system responses are generated, based upon the instructions of the detected voice input, - wherein the at least two system responses are generated by associated execution devices (2a, 2b, 2c), wherein priorities are defined for the execution devices (2a, 2b, 2c), - based upon the at least two system responses, at least two corresponding pieces of output data are generated, which comprise at least two corresponding pieces of output time data, wherein each piece of output data is assigned to at least one output device (4a, 4b), - wherein the output time data are generated as a function of the priorities of the respectively associated execution devices (2a, 2b, 2c) and both as a function of the input sequence and as a function of the respectively associated execution devices (2a, 2b, 2c), wherein such output data, which are visual output data, are combined for a common output, which are assigned to the same execution device (2a, 2b, 2c) by the visual output data being simultaneously output by an output device (4a, 4b) configured as a display device, and - each of the at least two pieces of output data is output by the associated output device (4a, 4b) according to the corresponding output time data. - a voice input with at least two instructions having an input sequence is detected, wherein a start and an end of the voice input is signaled to the voice-control system by the user or is automatically recognized by the voice-control system, and wherein the at least two instructions are input into the voice input such that several instructions are combined, - a machine-readable text from audio data of the voice input is generated, - a semantic analysis of the machine-readable text is carried out, - then, at least two system responses are generated, based upon the instructions of the detected voice input, - wherein the at least two system responses are generated by associated execution devices (2a, 2b, 2c), wherein priorities are defined for the execution devices (2a, 2b, 2c), - based upon the at least two system responses, at least two corresponding pieces of output data are generated, which comprise at least two corresponding pieces of output time data, wherein each piece of output data is assigned to at least one output device (4a, 4b), - wherein the output time data are generated as a function of the priorities of the respectively associated execution devices (2a, 2b, 2c) and both as a function of the input sequence and as a function of the respectively associated execution devices (2a, 2b, 2c), wherein such output data, which are visual output data, are combined for a common output, which are assigned to the same execution device (2a, 2b, 2c) by the visual output data being simultaneously output by an output device (4a, 4b) configured as a display device, and - each of the at least two pieces of output data is output by the associated output device (4a, 4b) according to the corresponding output time data.
