The Integrated Vocoder and its Application in Computer Systems

This paper reviews the conceptual features and the applications of the integrated vocoder. In a comparison with the structural properties of the channel vocoder and other experimental types, the integrated vocoder is shown to be a technically simple solution to the well-known problems of pitch description and vocoder signal transmission. The design reduces the complexity of the over-all speech processing equipment and features a saving in device hardware. The potential of this vocoder design for time division multiplex transmission systems is discussed and an application of the new vocoder concept is shown for computer input-output equipment.
