The distinct forms of five vowel sounds; a, e, i o and u. The bright bands in the visualisations show which frequencies are active in the voice, the further from the centre the higher the pitch. Time is wrapped around anti-clockwise to create a loop. Computers convert speech into patterns like this, so speech recognition can become pattern matching.  [inspiration] [code]

I post original stuff about maths, space, computational linguistics and other things that I like. This blog is meant to be accessible and interesting to people of all backgrounds. My undergrad was maths in Cambridge, and I'm now starting research in Speech and Language technology. Email me at If you're new, check out this overview of my posts. All code posted is in Mathematica.
