PURPOSE: to analyze the role of linguistic factors in the process of syllabic, consonantic and vocalic erasing on the speech of subjects with Verbal Dyspraxia. METHODS: phonologic analyses of seven subjects (2:6-4:2), with Verbal Dyspraxia diagnostic hypothesis. RESULTS: tonicity, word extension and sound class were the variables selected as relevant for the syllabic erasing. Other than those, on the consonant erasing, the syllabic structure is also relevant. On the vowel erasing only the tonicity and the syllabic structure were statistically significant. CONCLUSION: data from this research suggest the "metric foot tends to be produced more correctly, a prosodic structure where less erasing take place. The syllables most affected by erasing are those, which are just outside of the "metric foot".
