Title: Dictation system for storing and retrieving audio information

Abstract: A medialess dictation system for storing and retrieving audio information, and eliminating media handling requirements as well as recording and transcribing delays. During a recording operation, incoming audio information from an operator station is converted to digital information and temporarily stored in a limited capacity store. From the temporary store, this information is indexed and stored in a primary store. For a transcribing or playback operation wherein desired portions of previously recorded and indexed information are to be retrieved, the desired indexed information is addressed and transferred back to the temporary store. Thereafter, it is converted back to audio and output through the operator station.
