ABSTRACT:
A record playback system includes a display showing elapsed time of a record playback operation together with symbols indicating occurrences of certain sequences of sound during the playback operation, the symbols positioned to indicate times at which respective sequences of sounds occur. In a preferred application, the records reproduced in the system are audible voice-mail messages, the specific sequences of sounds are numbers or sets of numbers spoken consecutively during the message, and the symbols representing such numbers are printed characters corresponding to respective numbers. In the preferred application, the messages are centrally recorded at a server of a computer network and distributed to individual client computers via the network. The tasks performed at the server include monitoring of elapsed recording time, detection of numbers spoken during each message as the recording is made, and recording of "displayable" symbols representing detected numbers in association with elapsed time at instants of their detection. The detection of spoken numbers is performed by software-based speaker-independent speech recognition. Thus, the messages retrieved at the client computers contain all the information needed to form the display of elapsed time and symbols indicating numbers spoken in each message.
