1. An electronic device comprising:
a memory;
a sound sensor; and
a processor configured to:
receive, from the sound sensor, sound data comprising a first piece of data corresponding to a first frequency band, a second piece of data corresponding to a second frequency band, and a third piece of data corresponding to a third frequency band, the first frequency band, the second frequency band and the third frequency band being different from each other;
receive voice data related to a voice of a registered user from the memory;
perform voice identification by comparing the first piece of data, the second piece of data, and the third piece of data with the voice data related to the voice of the registered user in each relevant frequency band among the first frequency band, the second frequency band and the third frequency band; and
determine an output based on a result of the voice identification,
wherein the sound sensor comprises a plurality of mechanical oscillators configured to sense the sound data according to frequency bands,
wherein the plurality of mechanical oscillators comprise:
two or more first mechanical oscillators configured to sense the sound data in the first frequency band,
two or more second mechanical oscillators configured to sense the sound data in the second frequency band, and
two or more third mechanical oscillators configured to sense the sound data in the third frequency band,
wherein the processor is further configured to perform the voice identification by:
determining whether to accept or reject the first piece of data based on a similarity between the first piece of data and the voice data related to the voice of the registered user in the first frequency band,
determining whether to accept or reject the second piece of data based on a similarity between the second piece of data and the voice data related to the voice of the registered user in the second frequency band, and
determining whether to accept or reject the third piece of data based on a similarity between the third piece of data and the voice data related to the voice of the registered user in the third frequency band, and
wherein the processor is further configured to determine the output based on the result of the voice identification by:
determining final voice identification is successful based on a number of accepted pieces of data being greater than a number of rejected pieces of data, among the first, second and third pieces of data when at least one piece of data has been rejected.
