Abstract
An electronic device uses a voiceprint for user authentication, and includes a storage unit, a voice input unit, and at least one processor. The storage unit registers a first voiceprint based on first voice corresponding to a first character string and a second voiceprint based on second voice corresponding to a second character string longer than the first character string. The at least one processor generates a third voiceprint from third voice input to the voice input unit after registration of the voiceprint in the storage unit, and makes a first comparison between the first voiceprint and the third voiceprint as first user authentication. The at least one processor generates a fourth voiceprint from fourth voice input to the voice input unit after the third voice, and makes a second comparison between the second voiceprint and the fourth voiceprint, when the first user authentication has failed.
