A vowel is:
a) a speech sound that is made with the breath channel or vocal tract open, or without any audible friction.
b) a letter of the alphabet that represents any of these speech sounds.
The English vowel letters are Aa Ee Ii Oo Uu
The letter Y is traditionally counted as a consonant, but can be classed as both a consonant and a vowel.
In ‘hymn’ the letter Y is a vowel sound with the breath channel open.
In ‘yellow’ the letter Y is a consonant sound with the flow of air stopped in the mouth.
Vowels by Studiocanoe is a short film about vowels and vowel sounds based on a sound recording taken from the 1945 Linguaphone recording English Pronunciation: a practical handbook for the foreign learner (standard British / UK English).
I think it’s rather beautiful – what do you think?
