ABSTRACT:
A telephone exchange enables subscribers to use voice dialing more easily with existing telephone systems. The voice dialing does not require special input operations or preregistration of called parties. Rather, a subscriber can make a telephone call easily without having to perform multiple operations. The telephone exchange includes structure for discriminating dial pulse information, push-button tone information, and spoken information so that one or more of these types of information can be input by a caller to achieve connection to the called party.
