Recently a possibly new speech pattern has come to my attention and I am wondering whether it is genuine or whether I am mistaken. It is young, male native speakers emphasizing a deep, "rough" voice.
I've heard e.g. Americans and Australians do this, it can sound quite a bit forced and not genuinely "hulkish" (like when the natural voice may be higher), and sometimes even perplexing (such as in this recording, where an ex-soldier with PTSD reports how a drug used in his therapy makes him feel "like being hugged by everyone who loves you while lying in a bathtub full of puppies licking your face"; I call this perplexing because to me there is an odd mismatch between that voice and the message.)
My question is this: has this been observed before, i.e. are many young, male native speakers indeed laying on distinctive deep voices, or have I perhaps just encountered some random, unrelated cases?
