Lecture, perhaps, has Mike working with introduction, extracting press release (9)
I believe the answer is:
monologue
'lecture perhaps' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'mike working with introduction extracting press release' is the wordplay.
I cannot quite understand how this works, but
'mike' could be 'm' (phonetic alphabet: alpha, bravo, charlie etc.) and 'm' is found in the answer.
'working' could be 'on' (e.g. a machine is working or on) and 'on' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'has' is the link.
Can you help me to learn more?
(Other definitions for monologue that I've seen before include "Long dramatic speech by a single actor" , "Long and tedious speech" , "Soliloquy" , "speaking without interruption" , "Long speech by one actor" .)
