Have fun ! (but remember to brathe air sometimes between the helium fun, otherwise you will go KO or worse)

Answer 2

when we communicate air passes out from our lungs by our vocal chords and is led to to vibrate and also you listen the words. once you combine helium with air the ensuing mix is way less dense so as you breathe out the timbre of your voice is altered. The spped of sound in a a lot less dense helium/air mix is larger than in only air. you're increasing the speed of sound of your voice at the same time as respiration out this a lot less dense mix and this strengthen in speed will impression the frequencies that make up your 'voice'. If the frequencies are affected the timbre is affected too. A more advantageous dense gas would have an exceptionally wierd impression. Strictly talking even in spite of the indisputable fact that maximum persons say it is the pitch that variations, it is the really the 'timbre' it is replaced, as your vocal chords produce an analogous shapes and hence an analogous pitch.
