The first of the three Swedish characters. You’ll find the sound just before the L in words that contain AL, like: all, alter and Aldershot. Try saying ALL, but skip out the L’s. It should sound something like a mix of A and O, and it should come from the back of your mouth.
Ä is a rare sound in the British language. But if you try on an American accent and let out a fully fledge ass (or asshole), cut away everything after the A you’ll have the hang of it. It should sound something like a mix of A and E. Just as Å you’ll find the sound near your throat rather than the tip of your tongue.
Ö is the same letter as the Norwegian and Danish Ø. If you, once again, try that American accent you can hear the sound in words like: skirt, flirt, nerd, turd and bird. It’s the sound just between the U/I and the R.
