An example electronic device may include a memory configured to store instructions and a processor electrically connected to the memory and configured to execute the instructions. When the instructions are executed by the processor, the processor may be configured to generate a first suggested-utterance list providable to a user and generate a second suggested-utterance list by extracting, from the first suggested-utterance list, utterances capable of successful execution for a device registered to the user, according to state information about the registered device.
