Resumo<i>Objective:</i> Speech inconsistency is characterised by variable productions of the same lexical items within the same context. This study aimed to describe inconsistencies among Brazilian Portuguese (BP)-speaking children with and without phonological disorder (PD) as well as the effectiveness of a speech inconsistency test (SIT). <i>Methods:</i> The study sample included children between 5 years 0 months (5;0 years) and 10;10 years of age, both genders, 51 children with PD and 50 without speech-language disorders. The SIT includes 25 pictures, each named 3 times in different sequences within the same session. <i>Results:</i> The inconsistency average of children with PD (27.4%) was higher than that of typically developing children (9.8%). Linear regression showed age and gender effects, receiver operating characteristic curves were built for speech inconsistency with combined gender and age cutoff values. Inconsistent subjects among typically developing children included 2 younger boys and 2 older girls. Inconsistencies were found among children with PD, including 10 boys up to 7;6 years and 11 over this age, and 7 girls up to 7;6 years and 6 over this age. <i>Conclusion:</i> Speech inconsistency in BP-speaking children seems to be an effective measure for differentiating children with PD from those with typically developing phonology.
