Inhaling sulfur hexafluoride lowers your voice.

SUPPORTED
the evidence backs this
Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that inhaling sulfur hexafluoride lowers your voice?

Yes. Two popular-science books state that inhaling sulfur hexafluoride lowers or deepens the voice, and a chemistry Q&A and a physics text discuss the SF6 voice trick without stating the pitch change outright.
