VOICE CONTROLLED MESSAGING SYSTEM AND PROCESSING METHOD

摘要

A voice controlled voice-messaging system (1) permits manipulation of voice messages over the telephone without the need for keypressed commands. Manipulation includes playback of messages, deletion of messages, saving messages, and sending a new message to a recipient from a user-defined list. Access to the system is by spoken password. Voice input also allows: enrollment of a spoken password; granting or refusing user access to the system based on verification of the user speaking a password; recognition of spoken "yes" or "no" in response to prompts by the VMS; recognition of "stop" to interrupt and stop a voice message during playback; enrollment of a spoken personal directory of names of potential message recipients; and recognition of names in the spoken personal directory. The invention uses speaker verification, speaker-independent recognition (SIR) of "yes/no", speaker-independent recognition of "stop" during message playback, and speaker-dependent recognition (SDR) of limited vocabulary of short phrases such as a list of message recipients' names. Spoken password processing comprises calibration, enrollment and verification modes.
