(Of speech) throaty (8)
I believe the answer is:
guttural
(Other definitions for guttural that I've seen before include "Harsh-sounding, gravelly" , "(Of speech) produced in the back of the throat" , "Of speech, throaty and harsh-sounding like German" , "Harsh-sounding or throaty, like some languages" , "(Of speech sounds) produced in the throat" .)
