PURPOSE: to check the number of children, between 5:0 and 11:6-year old, with and without Phonological Disorder, Brazilian Portuguese speaking children that imitated correctly the liquid sounds in the stimulability test considering each one of the subsequent vowels. METHODS: the stimulability was measured in syllable imitation of 63 syllables with the sounds<img border=0 src="/img/revistas/rcefac/2009nahead/a06caros3.jpg" align=absmiddle> with seven oral vowels. We analyzed the percentage of subjects that produced correctly the sounds as a function of the subsequent vowel. RESULTS: the <img border=0 src="/img/revistas/rcefac/2009nahead/a06carL.jpg" align=absmiddle>was the sound with more correct productions, independent of the sequent vowel; the <img border=0 src="/img/revistas/rcefac/2009nahead/a06carR.jpg" align=absmiddle>was better produced with the vowels [ε, ó], and it seems that the medium-lower position height of the tongue is make easier the production of this sound; the <img border=0 src="/img/revistas/rcefac/2009nahead/a06carY.jpg" align=absmiddle>was better produced with the vowels [o, ó, u], it seems that the round position of the lips facility the production of this sound, as well the back and medium-upper position of the tongue. CONCLUSION: the vowels that are subsequent to the liquid studied sounds show influences in their productions, in such a way to make them easier.
