  • Patent number: 5668863
    Abstract: An innovative recording and playback system to record and play back audio conferences. In one embodiment, each conference participant's spoken name is recorded and stored in audio files. In addition, the combined voice signals generated by conference participants during the conference are stored in a conference data file. Data links are provided between the spoken names of the conference participants and the combined voice signals recorded during the conference. During playback of the recorded conference, a user can enter a command to an input device to playback the spoken names of the conference participants. In other embodiments, other conference information is stored in audio files and linked to the conference data file such that the information can be retrieved and audibly played back to the user.

  • Patent number: 5559875
    Abstract: An innovative recording and playback system to record and play back audio conferences. In one embodiment, the audio recorded during the conference is digitized and placed in blocks of a determined size. These blocks are stored on a computer storage medium such as a disk drive. A data structure is maintained consisting of an identification of the number and location of the voice blocks. Also provided in the data structure is the identification and location of blocks of data corresponding to the conference participants as well as the identification of other information associated with the conference. When the conference is to be played back by the user, the data structure and corresponding blocks are accessed to play back the conference as well as selectively provide the additional information, for example, the spoken names of the conference participants, to the user.
