RESUMO
OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSION: Speech inconsistency in BP-speaking children seems to be an effective measure for differentiating children with PD from those with typically developing phonology.

OBJECTIVE: Stimulability is the ability to produce an adequate sound under specific conditions. This study aimed to describe the stimulability of Brazilian Portuguese-speaking children with and without phonological disorders for the production of liquid sounds with the aid of visual and tactile cues. PATIENTS AND METHODS: The study sample included 36 children between 5;0 and 11;6 years of age, 18 with phonological disorder and 18 without any speech-language disorders. Stimulability was measured for syllable imitation. The stimulability test employed includes 63 syllables with the sounds [i], [lh], and [r], as well as seven oral vowels. If the subject was unable to imitate a sound, a visual cue was given. When necessary, a tactile cue was also given. RESULTS: The sound [lh] required greater use of sensory cues. Children with phonological disorder needed a greater number of cues. CONCLUSION: The use of sensory cues seemed to facilitate sound stimulability, making it possible for the children with phonological disorder to accurately produce the sounds modeled.
