PROBLEM TO BE SOLVED: To provide a device and method for speech recognition which prevent misrecognition of a speech resulting from the depression timing of a talk switch by a user or a malfunction due to noise. SOLUTION: The device comprises a detection part 21, a speech input part 22, a speech holding part 23, a delay circuit 24, a talk switch 25, a speech detection part 26, and a speech recognition part 27. When the user presses the talk switch 25, the speech detection part 26 detects a speech section and performs speech detection including a speech that the speech holding part 23 holds. Following output from the speech holding part 23, the delay circuit 24 outputs an input speech delayed by the time equivalent to that of the length of the speech that the speech holding part 23 holds, the speech detection part 26 processes the input speech, and the speech recognition part 27 recognizes it.
