[email protected] This paper extends the same hypothesis to the phenomenon ABSTRACT of spirantization by investigating the interaction of phonetic factors with inventory constraints. First, it This paper examines the effect of inventory constraints and examines whether the phonetic factors of stress and vowel the phonetic factors of stress and vowel context in the context, which had an effect in the lenition of Spanish lenition of English and Spanish intervocalic voiced stops. intervocalic /g/ [3], had also an effect in English Five native speakers of American English and five native intervocalic /g/ and in Spanish and English intervocalic /b/. speakers of Caribbean Spanish were recorded saying Secondly, this paper studies the interaction of inventory bi-syllabic words containing intervocalic /b/ and /g/. The constraints with phonetic factors. Inventory constraints intervocalic consonants were evaluated according to two were aimed to preserve the system of sound contrasts of a measures of energy, i.e. RMS ratio, and speed of consonant language while phonetic factors provided contexts that release. Repeated Measures ANOVAS in each measure favored consonant lenition. Hypothetically, a consonant indicated that for both languages, /b/ and /g/ were most will become lenited in a favorable context only if the lenited in trochee words, and that /g/ was most spirantized resulting sound will not impair a contrast of the language. when flanked by /i/ and /u/ vowels. Inventory constraints For example, in English, /b/ contrasts with the voiced moderated the degree of consonant lenition displayed in the fricative /v/ while in Spanish, it does not.
