  • Patent number: 6246983
    Abstract: A multi-user e-mail reader system allows several users to access their e-mail accounts simultaneously and have the e-mail messages played back with speech synthesis. The user navigates through various functional states of the system using either touch-tone keypad commands or optionally voiced commands interpreted by a speech recognizer. Users can send reply e-mail messages without the use of a computer, by invoking the system's text processor. The text processor operates in conjunction with a keypad-to-ASCII conversion mechanism that allows fully punctuated and properly addressed e-mail messages to be composed from the touch-tone phone. Digital audio sound file attachments may be recorded through the telephone handset and attached to an outgoing e-mail message. A system for storing canned messages allows the user to quickly send pre-composed reply messages, either as stored or after editing using the text processor.
