Portrayal in speech holds record (9)
I believe the answer is:
depiction
'portrayal' is the definition.
(I know that portrayal can be written as depiction)
'speech holds record' is the wordplay.
'speech' becomes 'diction' (diction is someone's way of speaking).
'holds' is an insertion indicator.
'record' becomes 'EP' (abbreviation for extended play record).
'diction' placed around 'ep' is 'DEPICTION'.
'in' acts as a link.
(Other definitions for depiction that I've seen before include "drawing" , "picture" , "Portrayal" , "Representation in art" .)
