Stimuli used in research on the perception of the speech signal have often been obtained from simple filtering and distortion of the speech waveform, sometimes accompanied by noise. However, for more complex stimulus generation, the parameters of speech can be manipulated, after analysis and before synthesis, using various types of algorithms to…

The sentence processing abilities of a conduction aphasic adult woman with a documented phonological coding deficit were investigated in tests of auditory and visual sentence comprehension of reversible active and passive sentences and spatial prepositions, sentence production through story completion and picture description, and repetition of…

Videotaped productions of isolated American Sign Language signs or sentences were presented at speeds of two to six times normal. Results indicated a breakdown in intelligibility at around 2.5 to 3 times the normal rate. Results are similar to those found for auditory reception of time-compressed speech suggesting a modality-independent limit to…

Describes three experiments that examined the processing of speech by dyslexic readers. Compares their performance with that of age-matched and reading-ability-matched controls. Shows that dyslexics have difficulty with the nonlexical procedures involved in verbal repetition. (HOD)

Investigates how feedback from a listener helps kindergarteners attend to message quality and how such feedback affects speaking and listening skills. Results indicate that kindergarteners learn to assess message adequacy by observing listeners flounder with inadequate messages.(Author/AS)

Twenty reading-disabled, 10 math-disabled, and 25 control-group college students were assessed on a battery of psychophysical tasks that included 5 tests of temporal processing. Findings suggest that poor temporal processing is neither a necessary nor a sufficient cause of reading disability but that there is a modest association between the two…
