PROBLEM TO BE SOLVED: To provide a voice detection device for surely detecting the contents of utterance. SOLUTION: When outputs of both an air conductive microphone 1 and a bone conductive microphone 3 exceed a predetermined level for each unit time, the correlation value is calculated. When it is determined that correlation is high, time information is sent to a voice section detection section 7, and thereby, a section which is surely assumed to be a voice section, can be utilized at the time of voice detection.
