DSI: Digital Speech Interpolation
Digital Speech Interpolation (DSI) is a technique of sharing voice communication paths among a larger number of users by means of allocating the silent periods inherent in human speech to active uses. An earlier technology was called Time Assignment Speech Interpolation or TASI. The technique is somewhat analogous to that of the statistical multiplexing of data transmission.
