None of the dictionaries I checked records pronunciation of the pronoun us with a terminal /z/ (not due to assimilation to the subsequent word either), which I’ve been hearing more and more frequently lately (last example — somewhere in the fish and scripts podcast). Here’s from Cambridge Advanced Learner’s:
- Boris pronounces visceral with a /k/ (I’ve already marveled at his eviscerate behaving the same).
- He also pronounces Erdogan with a /g/. None of that /w/ nonsense.
