Two matched groups of severely language impaired school children (SLI) participated in a 4-week long training program consisting of daily sessions with computer-based speech and language games during which they listened to manipulated speech. For one of the groups the auditory stimuli were simply embedded in pink noise (S/N=3 dB) while for the other the same original stimuli were temporally and spectrally modified in line with Tallal's et al. (1996) transform. Pre- and post training assessments of the children's psycholinguistic age ratio showed that children in both groups had a significant improvement from in psycholinguistic age from pre- to post-training but that there were no significant differences between the "noise" and the "transform" groups. This outcome is discussed against the background of poorly defined phonemic categories in SLI children and dyslexics.
