5. A speech recognition apparatus comprising: inputting means for inputting a speech signal; prosody identifying means for identifying prosody on the basis of an amount of change in movement of a feature distribution obtained from an autocorrelation matrix of a frequency characteristic of the input speech input to the inputting means; and speech recognizing means for performing speech recognition on the basis of features acquired by sound-analyzing the speech input to the inputting means; and selecting means for selecting whether to output an output of the speech recognizing means or to integrate the output from the prosody identifying means with an output of the speech recognizing means and output the integrated output, the selecting means outputting the selected output.
