Microprocessor-controlled speech pattern audiometry. Preliminary results

Interactive microprocessor-controlled speech pattern tests making use of high-quality synthetic speech have been used to assess the development of subjects' ability to process speech contrasts of increasing complexity, from prosodic contrasts to a 'date-gate' place contrast. These tests have been particularly useful in mapping the development or recovery of subjects functioning at the very first stages of processing ability. Some results obtained with profoundly hearing-impaired children and with adults suffering from brain stem disorders are reported, and further applications of speech pattern audiometric techniques are briefly discussed.
