Answer:
Our vocal cords vibrate at the same frequency, but our voice changes with helium because the gas affects our tone or sound quality by allowing sound to travel very fast the speed of our voice increases. This then changes the resonance of our vocal tract by making it highly responsive to high-frequency sounds.

Answer:
That's because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out. ... It's a gas that is much heavier than air, so when it is inhaled, it shortens sound waves so the lower tones in the voice are amplified and the higher ones fade out.
