pronounced as /notice/In phonetics and phonology, an intervocalic consonant is a consonant that occurs between two vowels.[1] Intervocalic consonants are often associated with lenition, a phonetic process that causes consonants to weaken and eventually disappear entirely. An example of such a change in English is intervocalic alveolar flapping, a process (especially in North American and Australian English) that, impressionistically speaking, replaces /t/ with /d/. For example, "metal" is pronounced pronounced as /[mɛɾl]/; "batter" sounds like pronounced as /['bæ.ɾɚ]/. (More precisely, both /t/ and /d/ are pronounced as the alveolar tap pronounced as /[ɾ]/.) In North American English, the weakening is variable across word boundaries, such that the /t/ of "see you tomorrow" might be pronounced as either pronounced as /[ɾ]/ or pronounced as /[tʰ]/.[1] Some languages have intervocalic-weakening processes fully active word-internally and in connected discourse. For example, in Spanish, /d/ is regularly pronounced like pronounced as /[ð]/ in the words "Spanish; Castilian: todo" pronounced as /[ˈtoðo]/ (meaning "all") and "Spanish; Castilian: la duna pronounced as /[laˈðuna]/", meaning "the dune" (but pronounced as /[ˈduna]/ if the word is pronounced alone).
