PROBLEM TO BE SOLVED: To provide a speech recognition device in which speech recognition is accurately conducted, a speech recognition processing can be conducted by a user with game feeling and the user learns new vocabulary in a natural manner. SOLUTION: Voice uttered by the user is inputted into a voice input section 1 and outputted to a featured values extracting section 2 as voice signals. The featured values extracting section 2 computes an acoustic featured vector of the voice signals and transmits the vector to a recognition section 5. The recognition section 5 refers to the acoustic featured vector and an acoustic model 3 and extracts a vocabulary, whose likelihood becomes higher, from a recognition vocabulary holding section 4. The recognition section 5 transmits the recognition result and the likelihood to a score computing section 6. The score computing section 6 displays the computed likelihood as a score on the display section 8 when the recognition result and the vocabulary inputted into a vocabulary selecting section 7 are matched with each other. Thus, the user learns the uttering method, in which likelihood becomes higher in a natural manner, because the score given to the user becomes higher as the likelihood of the inputted voice becomes higher.
