110375 NRL "English Text to VOTRAX Parameters Algorithm" Version: November 1978 Submitted by: L. Robert Morris, Carleton University, Ontario, Canada Operating System: RT-11 V02C or later Source Language: FORTRAN IV; MACRO-11 Memory Required: 16K or more Hardware Required: VOTRAX Synthesizer, Parallel Interface (DR-11-C) Keywords: Libraries - RT-11 Abstract: Fast FORTRAN/RT-11 SYSLIB Software for implementing the NRL "English Text to VOTRAX Parameters Algorithm". Computers can "speak" by computing parameters which are output to speech synthesizers. The VOTRAX synthesizer has found widespread applications and is available as a "professional" model (from its manufacturer, Federal Screw of Troy, Michigan 48084) and in a "hobbyist version (from "the Digital Group", PO Box 6528, Denver, Colorado 80206). Either model can be driven from a log-rate parallel interface with a "phoneme" string derived from the text to be spoken. This software system utilizes the RT-11 SYSLIB string manipulation routines to efficiently implement the U.S. Naval Research Labs "English-to-VOTRAX" algorithm. The software runs in real-time (or less) on any PDP-11, including the LSI-11. A parallel interface (e.g. DR-11C) is required. The software will run on a 16K system under RT-11 V02C.
