Children with Speech Sound Disorder (SSD) have been found to show following ie, enhancing responses to formant perturbations. A possible mechanism is that the sensory motor system interprets the formant shifts as adjustments of the intended auditory outcome, following a strategy not aimed at neutralizing but at matching the perceived formant error. The present study explored this hypothesis through a modeling experiment with SimpleDIVA, with which certain model parameters were fitted to behavioral data from three groups of Dutch speakers: 6 children with SSD compared to 17 typically developing (TD) children and 50 healthy adults. Results showed a negative feedforward control/learning rate in the children with SSD while this parameter approximated 0 in adults and 1 in TD children. Findings suggest that children with SSD process the perturbed auditory signal as an external cue. Detailed results and discussion of experimental considerations/limitations will be available at the conference.
