Everyone should absolutely at least once pronounce every letter from the alphabet and look at a spectrogram, it’s fascinating.

Try a rolled “r”, vowels, consonants, “p”, “f” (“eeeffff”) etc.

Also try whistling if you can.

Online spectrogram options:

Sort of works on mobile, go to landscape and tap the mic button: https://spectrogram.sciencemusic.org/

Doesn’t work on mobile anymore? But should be good desktop option: https://musiclab.chromeexperiments.com/Spectrogram/
