For that, we use a sonority hierarchy in which the sonority degree of non-sibilant obstruents equals 0, sibilant obstruents 1, nasals 2, liquids 3, glides 4 and vowels 5. Thus, consonantal clusters in the same syllable are well-formed, or faithful to the input when the sonority distance is +3; for instance, the sonority rises from 0 to 3 in the sequences 'pr' and 'bl' in words like prato 'dish' and blusa 'blouse' (p= 0 and r= 3, b= 0 and l =3). In clusters with a sonority distance lesser than +3, such as sp in words such as 'sports' (s=1 and p=0; and pt in words such as 'ptose' and 'ptosis' (p=0 and t=0), there is a vowel before the sibilant or between the consonants, [i]sport e p[i]tose. While heterosyllabic consonantal clusters whose sonority distance falls - [j.t] jeito 'way' (-4), [r.t] parte 'part' (-3), [l.d] saldo 'balance' (-3), [n.t] santo 'saint' (-2), [s.p] caspa 'dandruff' (-1) - are faithful to the input, clusters with plateau or rising sonority distance - ritmo 'rhythm' (0), [p.s] opção 'option' (+1), [p.n] apneia 'apnea' (+2) - are broken by an epenthetic vowel, rit[i]mo, op[i]ção, ap[i]neia. In this analysis, we propose two constraint hierarchies in order to regulate the sonority distance between segments within a complex onset and in adjacent syllables: *ONS DIST and *DIST, respectively. We argue that the interaction among these constraints and faithfulness constraints - OUTPUT-CONTIGUITY (no internal epenthesis), DEP (no epenthesis) e MAX (no deletion) (McCarthy & Prince, 1995) - is responsible for the faithful mapping of the consonantal clusters and for the occurrence of vocalic epenthesis. Furthermore, we argue that the epenthesis site depends on the interaction between OUTPUT-CONTIGUITY and *DIST.
