1. An information apparatus that generates a first acoustic model for speech recognition, the information apparatus comprising:

  • a first speech dataset storing speech data uttered by low recognition rate speakers;

    a second speech dataset storing speech data uttered by a plurality of speakers;

    a third speech dataset storing speech data to be mixed with the speech data of the second speech dataset;

    a similarity calculating part obtaining, for each piece of the speech data in the second speech dataset, a degree of similarity to a given average voice in the first speech dataset;

    a speech data selecting part recording the speech data, the degree of similarity of which is within a given selection range, as selected speech data in the third speech dataset; and

    an acoustic model generating part generating a first acoustic model using the speech data recorded in the second speech dataset and the third speech dataset.
