Engaged, made speech in favour (6,3)

I believe the answer is:

spoken for

'engaged' is the definition.
(I've seen this before)

'made speech in favour' is the wordplay.
'made speech' becomes 'spoken'.
'in favour' becomes 'for' (I've seen this before).
'spoken'+'for'='SPOKEN FOR'

(Other definitions for spoken for that I've seen before include "Having romantic commitment" , "Not a single" , "Unavailable (as a partner)" , "Sold!" , "Already claimed" .)

I've seen this clue in The Times.
