Speech audiometry by a speech synthesizer. I. A preliminary report.

A preliminary report on speech test results with a portable, text-to-speech synthesizer is presented. The differentiation scores achieved at speed 80 words/min vary. So far the best mean differentiation scores in normal material are 75%. The increase of the presentation level improves the differentiation score, as does the decrease of word speed and training. The future and present uses of this system are discussed. These include: devices for the handicapped, e.g. to produce speech for the mute, man-machine communication through speech in industry control, data processing systems and uses in audiological diagnostics. The study is continued.
