To provide a voice recognition device having a low erroneous recognition rate.
When a request is made to initiate voice recognition (S101), a voice recognition process is conducted (S103) and plural candidate words and respective likelihood are computed (S105). Then, decision is made to determine whether noise is recognized or not based on both the likelihood difference between first and second candidates and noise power ratio (S107).
