摘要：Objective: to analyze the influence of different combinations of verbal stimuli on the responses of the cognitive auditory evoked potential of children with speech sound disorders and to compare the P300 responses, considering the combinations of stimuli in the different severity of speech sound disorders. Methods: nineteen children in the mean age of 6.75 years old, of both sexes, diagnosed with speech sound disorder, participated in the study. All participants were submitted to the cognitive auditory evoked potential - P300 test, performed with two combinations of verbal stimuli (BA/DI and BA/GA). For statistical analysis it was used the Student T-test. Results: a statistically significant difference was observed for the latency values (p=<0.001*) and for the amplitude values (p=<0.001*) between the two combinations of stimuli. Also, statistically significant difference was observed between the combinations evaluated in the different severity of the speech sound disorder. Conclusion: the combination of stimuli /BA/ x /DI/ demonstrated lower latency and higher amplitude values in the Cognitive Evoked Potential assessment in children presented with speech sound disorder.
