I hope this question fits the group.
As a teacher of EFL I have come across this question several times:
Question: Does "/kləʊðz/" provide the right phonemic representation of the final sound in the word "clothes"?
"Oxford Learner's Dictionaries" gives four variants. In both BrE variant recordings, what I hear is a final unvoiced /s/ sound, and this is also the way I pronounce it. The dictionary seems to transcribe the final sound in both cases of BrE as voiced /z/-sound. (see Oxford Learner's Dictionaries, "Clothes")
Collins Dictionary, explicitly states that their phonemic representions follow Received Pronunciation:
The accent represented by the pronunciations in this dictionary is Received Pronunciation.
gives the same transcription of "clothes".
It seems practically impossible to me (let alone to my students) to actually realise the pronunciation suggested by the phonemic representation provided.
