Abstract:

This report documents the design and implementation of a Voice Response System VRS using Adaptive Differential Pulse Code Modulation ADPCM voice coding. Implemented on a Digital Equipment Corporation PDP-1120,R this VRS system supports a single audio-output channel. Vocabulary size is limited to 900 words or phrases. Input to the system consists of text messages or sentences in ASCII format transmitted to the 1120 through a 300-baud asynchronous interface. A preliminary design for a VRS for 10 channels is reported.
