Input and Output Mechanisms and Devices. Phase I: Adding Voice Output to a Speaker-Independent Recognition System.
Scott Instruments Corp., Denton, TX.
This project was designed to develop techniques for adding low-cost speech synthesis to educational software. Four tasks were identified for the study: (1) select a microcomputer with a built-in analog-to-digital converter that is currently being used in educational environments; (2) determine the feasibility of implementing expansion and playback routines of compressed speech files on the targeted microcomputer; (3) test the target microcomputer using various bit rates; and (4) determine the feasibility of incorporating speech output capability into an authoring system currently being developed for speech recognition. The Apple Macintosh was selected, and routines were developed in the Pascal programming language for expanding and playing speech files at various data rates. It was found that the Macintosh is capable of producing a range of synthesized speech and that it is necessary to provide the courseware developer with a selection of bit rates. (MES)
