Spoken part doctor originally played? Something fishy here (7)
I believe the answer is:
rollmop
'something fishy here' is the definition.
(type of herring fillet)
'spoken part doctor originally played?' is the wordplay.
'spoken part' becomes 'roll' (I am not sure about this - if you are sure you should believe this answer much more).
'doctor' becomes 'mo' (medical officer).
'originally' says to take the initial letters.
The first letter of 'played' is 'p'.
'roll'+'mo'+'p'='ROLLMOP'
(Other definitions for rollmop that I've seen before include "Pickled herring wrapped around onion slices" , "Pickled fillet of raw herring" , "Dish of herring fillet" , "Curled-up herring fillet" , "Fish" .)
