Delivery address (6)
I believe the answer is:
speech
I believe this is a double definition.
'delivery' is the first definition.
('speech' can be a synonym of 'delivery')
'address' is the second definition.
('speech' can be a synonym of 'address')
(Other definitions for speech that I've seen before include "Formal talk to an audience" , "Verbal communication" , "Harangue" , "The spoken word" , "'Utterance, talk (6)'" .)
