Telephonic communication

摘要

A back end facility (40) is provided which is responsive to voice commands from a cellular telephone device (10). The cellular telephone device (10) connects automatically with the back end facility (40) and maintains a data link with the back end facility (40) via the cellular network (60). Voice commands from a user are digitized and sent as data to the back end facility (40). Voice recognition is then utilized to identify the command and respond thereto. The back end facility (40) may then establish a speech connection, via the network (60) between the device (10) and some other telephone (10, 64, 68); send a message to some other instrument via the cellular network, the Internet (70), a LAN or WAN; verify the identity of a user; or supply authorization signals.
