Reportedly permitted to be audible (5)
I believe the answer is:
aloud
'be audible' is the definition.
(I've seen this in another clue)
'reportedly permitted' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'permitted' becomes 'allowed' ('allow' can be a synonym of 'permit').
'allowed' sounds like 'ALOUD'.
'to' is the link.
(Other definitions for aloud that I've seen before include "Not sotto voce" , "it is said" , "For all to hear" , "At some volume" , "Using the voice, not silently" .)
