I can't find a quick guide to the pronunciation of the different vowels in combination with j.

uj confuses me in particular, but I'm sure the others do too (I just haven't realized it yet). If someone can clarify or point me to the right place, it would be helpful.

Dankon!

The uj sound is very similar in sound to how one would pronounce the word 'we'. Try to make the Esperanto 'u' sound followed quickly by the sound of the Esperanto 'i'. It ends up sounding like 'ooee' like the ending of the word 'gooey'. I hope that helps.

Je me souviens.

you (en)=ju (EO)
you, youyou, ouyou, and now without the final vowels ou --> ouyou = uj

do the same with others vowels
aya, eye, iyi, oyo --> aj, ej, ij, oj

Remember the mexican mouse "Speedy Gonzales" saying in EO "aja jaj jaja jajaj..."

a i e o and u are the experanto vowels. They are known as pure vowels (which means that the shape of your mouth doesnt change when you sound them).

j and ŭ are what are known as semivowels. They can act as a vowel or a consonant depending on how they are used. When they are used with other vowels they make diphthongs (two vowel sounds that are combined into one syllable - here the shape of the mouth will change as you "glide" from one vowel sound to another).

consider aj this is a combination of the ah and yuh sounds. But when crammed together in one syllable, it rhymes with the english word eye.

A basic guide to the other sounds is given below:

aj like the y in sky or the ai in aisle.
ej like the ei in vein, or the ey in they.
oj like the oi in coin, or the oy in boy.
uj like the ui in ruin, or the ooey in gooey.
eŭ like ayw in wayward, or like e(h)oo pronounced together.
aŭ like ou in out, ow in owl.

Also note ŭ almost always appears with a and e as above. There are very few words where it is used by itself. when it is, it sounds like the english w in win

Hope that helps.
