Summary:PROBLEM TO BE SOLVED: To provide a speech recognition device and a navigation device using the same, which recognize a speech recognition unit output from a user with high accuracy without fail. SOLUTION: In the speech recognition device, a speech buffer is emptied in order to store speech signals sequentially input from a microphone (S400), and the speech signal input from the microphone is stored in the speech buffer (S402), until a tempo signal for generating tempo sound from a speaker at fixed time intervals is output (S404:Yes). When speech of the user is stored in the speech buffer (S406:Yes), the speech recognition device compares the speech signal in the speech buffer with a reference speech pattern, based on the predetermined speech recognition unit output from the user, for example, single-digit number or one mora, and recognizes the speech signal for each recognition unit (S408). When the speech signal is recognized in one recognition unit, processing proceeds to S400, to store the speech signal in the speech buffer until the next tempo signal is output.
