Vocal type of bard from Labrador (4)
I believe the answer is:
oral
'vocal' is the definition.
(thesaurus)
'type of bard from labrador' is the wordplay.
'type of' is an anagram indicator (I've seen 'type' mean this).
'from' indicates named letters should be taken away.
'labrador' with 'bard' taken out is 'laor'.
'laor' with letters rearranged gives 'ORAL'.
(Other definitions for oral that I've seen before include "language exam" , "Type of exam" , "Spoken, of the mouth" , "Type of examination" , "Spoken exam" .)
