Help with Sonnet 75

Hi,

I wonder if anyone can help me, please?


A few years ago I was studying dialects and accents and I recall something about Sonnet 75 being perfect to hear differences with because it contained ... and there my memory of it fades :( I think it was every vowel sound in the English Language but I'm really not sure. All I am I sure of is it contained every "something".

Do you know if it's true that it has every vowel sound in it? Or was it every consonant?

Any thoughts?

I've never heard of that but here is a good link to analysis of the Sonnet 75
