Dynamic TTS and Voice Chat Pitch Shifts Near Sulfur Geysers.

Minecraft recently added the sulfur cube update, and theres a geyser that gives you Nausea from a gas that releases,so I was wondering if you could make the TTS and Voice Chat sound deep. This would be incredible because it matches the real science behind sulfur hexafluoride, if you breathe in hexafluoride, your voice becomes deep because the gas is 5x more dense than air, thanks for reading this. See ya!
