Abstract
Telephone apparatus in which a call may be made in response to utterances of a user by speech recognition without manually dialing a telephone number. The telephone apparatus includes a storage device for storing a set of parameters corresponding to an expected speech signal, which are used for recognizing the user's subsequent utterance and/or for indicating differences between the utterance and the stored signal. The telephone apparatus further includes a storage device for storing the speech signal so that the stored speech signal can be reproduced. The reproduced speech signal is used to confirm the stored speech signal. The stored speech signal may be reproduced in response to a user's key operation when the telephone apparatus is in a confirmation mode and in response to a user's utterance when the telephone apparatus is in a registration or voice calling mode.
