Intervocalic consonant

[citation needed] 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/.

In North American English, the weakening is variable across word boundaries, such that the /t/ of "see you tomorrow" might be pronounced as either [ɾ] or [tʰ].

[1]: 96  Some languages have intervocalic-weakening processes fully active word-internally and in connected discourse.

For example, in Spanish, /d/ is regularly pronounced like [ð] in the words "todo" [ˈtoðo] (meaning "all") and "la duna [laˈðuna]", meaning "the dune" (but [ˈduna] if the word is pronounced alone).
