1. A voice actuated dialing apparatus comprising:

  • input/output means for inputting and outputting data;

    feature extraction means for extracting a feature of input data received through said input/output means;

    storage means for storing standard patterns and corresponding telephone numbers of destination subscribers as registered data;

    pattern matching means for comparing a standard pattern of the feature extracted by said feature extraction means with the standard patterns stored in said storage means so as to recognize a predetermined one of the stored standard patterns which matches the standard pattern of the extracted feature;

    speech synthesis means for outputting through said input/output means a speech corresponding to said predetermined stored standard pattern read-out from said storage means so as to confirm a result of the recognition made in said pattern matching means;

    dialing means for dialing of a predetermined one of the telephone numbers stored in said storage means and corresponding to said predetermined standard pattern in a voice-dialing mode; and

    control means for controlling operation sequences of said feature extraction means, said storage means, said pattern matching means, said speech synthesis means and said dialing means;

    said control means successively outputting to said input/output means at least a part of the registered data stored in said storage means in response to a search instruction received from said input/output means designating the part to be successively outputted;

    said pattern matching means having a preliminary selection part and a main selection part, said preliminary selection part in response to the search instruction comparing a certain portion of the standard pattern of the feature extracted by said feature extraction means with corresponding portions of the standard patterns stored in said storage means when the search instruction accompanies a subject of search so as to select specific standard patterns having a certain similarity to said certain portion, said main selection part comparing the standard pattern of the feature extracted by said feature extraction means with only said specific standard patterns so as to recognize the predetermined one of the specific standard patterns which mates the standard pattern of the extracted feature.
