Coarticulation
When articulation of one sound influences adjacent sounds in connected speech.
Real World
Speech-to-text software like Apple's Siri often misrecognises words because coarticulation causes speakers to round their lips for an upcoming /uː/ while still producing a preceding consonant, blurring sound boundaries.
Exam Focus
Use coarticulation as the umbrella explanation when identifying multiple connected speech features in a single transcript extract.
