ABSTRACT:
A voice controlled automatic dialer comprises a speech analyzer for generating a signal representative of characteristic patterns of an input utterance entered through a microphone, and a first memory for storing a plurality of reference signals representative of predetermined characteristic patterns of utterances of dialing numbers and command words, the predetermined characteristic patterns being representative of utterances common to any users. A second memory stores a plurality of reference signals representative of specific characteristic patterns of utterances of dialing names which are defined by authorized users. The output signal of the speech analyzer is compared with the reference signals stored in the first and second memories and an output is generated as representative of least distances between the characteristic patterns of the input and the stored patterns. The result of the comparison is indicated by a synthesized speech or a multifrequency tone to permit users to confirm the validity of the input utterances. A manually operated switch couples the output of the speech analyzer to the second memory when it is desired to store a user-specific dialing name into the second memory after a training process.
