Abstract: An electronic device includes a communication circuitry, a microphone, a speaker, a memory, and a processor. The processor may identify a first audio signal received through the microphone. The processor may perform, based on identifying that the first audio signal may include a speech for sequentially executing a plurality of functions, at least one first function from among the plurality of functions. The processor may perform, based on identifying that the first audio signal may include the speech, at least one second function from among the plurality of functions on an external electronic device through the communication circuitry, the at least one second function being different from the at least one first function. The processor may sequentially output, through the speaker, at least one second audio signal representing at least one result of performing the at least one first function and the at least one second function based on a sequence associated with the speech.
