I tried this a total of 3 times during very stressful thesis. No point in me doing it now. The third time I tripped so bad I thought my voice was going Barry White deep.
Everyone was egging me on like, "Yeah your voice is SO deep wtf happened to your throat?!" "I think your pharynx is broken!" And I started freaking out. Turns out, I only I could hear my voice like that. And my friend was freaking out because she thought my eyes were blue (the white part of my eyes).
