While the position of the tongue is

more or less stable for a pure vowel

a diphthong is characterised by a

graceful movement from one pointto another, for this reason they arealso sometimes known as glides

This is also visible on a spectrogram:

this is the pure vowel /a/


7/33

Notice how the formants (the dark bands)

separate towards the end.
