Assimilation Place Assimilation Germanic Phonetic Process

Voiceless alveolar plosive to Voiceless bilabial plosive

The phonetic transformation of a voiceless alveolar plosive /t/ to a voiceless bilabial plosive /p/ is primarily observed as a regular process of regressive place assimilation in connected speech. This occurs when /t/ is followed by a bilabial consonant (/p/, /b/, or /m/), where the articulation of /t/ shifts forward to the bilabial place of articulation of the subsequent sound, making pronunciation easier. While often a synchronic phonetic phenomenon, such regular phonetic biases can contribute to diachronic sound change over time.

Language Examples

English

white paper→whipe paper— The /t/ at the end of 'white' assimilates to /p/ before the bilabial /p/ in 'paper'.

night before→nip before— The /t/ at the end of 'night' assimilates to /p/ before the bilabial /b/ in 'before'.

bit more→bip more— The /t/ at the end of 'bit' assimilates to /p/ before the bilabial /m/ in 'more'.
