Flapping Allophony Germanic Connected Speech

Voiced alveolar plosive to Voiced alveolar flap

The voiced alveolar stop /d/ surfaces as the voiced alveolar flap [ɾ] in intervocalic position in North American English, paralleling the allophonic variation of /t/ → [ɾ]. This creates phonological neutralization between /t/ and /d/ in this environment, resulting in homophonous pairs like metal/medal, though the underlying contrast remains in the phonemic system.
