Ö = O-Umlaut
To pronounce “ö” as you should, you need to form your lips as in “o” first, and again imagine somebody pulling on your lips. We can compare it with when you say “her” in English. The sound between the letters “h” and “r” is the sound you need.
Your tongue should also be away from the top part of the mouth. Then you make the sound by bringing in the lips in a circular manner and the tongue moving upward and towards the front of the mouth ending right in the middle. If you combine the "oh" and "oo" sound, you have the sound of the letter "O".
So remember, the letter “O” has more than one sound, and it is usually pronounced with one of the three basic sounds: Long-O, Short-o, and Short-o-2 (or schwa).
The O umlaut is one of three German vowels that does not exist in the English alphabet. Ö does not have an equivalent sound in English. It's kind of like the sound you'd make when disgusted by something.
Ö or ö is one of the 4 extra letters used in German. It can be replaced by using the letters Oe or oe. In English language newspapers it is often written as O or o but this is not correct.
As with so many vowels, it has slight variations of "light" quality (in Danish, søster ("sister") is pronounced as [ø], like the "eu" in the French word bleu) and "dark" quality (in Danish, bønne ("bean") is pronounced as [œ], like the "œu" in the French word bœuf).
Ó, ó (o-acute) is a letter in the Czech, Emilian-Romagnol, Faroese, Hungarian, Icelandic, Kashubian, Polish, Slovak, and Sorbian languages. This letter also appears in the Afrikaans, Catalan, Dutch, Irish, Nynorsk, Bokmål, Occitan, Portuguese, Spanish, Italian and Galician languages as a variant of letter "o".
Silent O words
The letter O is silent in some words that pair it with fellow vowels E and U, such as people, jeopardy, leopard, rough, tough, enough, trouble, and double.
Ö, or ö, is a character that represents either a letter from several extended Latin alphabets, or the letter "o" modified with an umlaut or diaeresis. In many languages, the letter "ö", or the "o" modified with an umlaut, is used to denote the close- or open-mid front rounded vowels [ø] ( listen) or [œ] ( listen).
A diaeresis is a mark placed over a vowel to indicate that the vowel is pronounced in a separate syllable—as in 'naïve' or 'Brontë'. Most of the English-speaking world finds the diaeresis inessential. The New Yorker may be the only publication in America that uses it regularly.
– “ü” as in müde is like a Scottish person saying “grew” Make the sound “ee” as in “cheese” and then make your lips into an “o” shape. – “ö” as in blöd is like an English person saying “burn” Make the sound “a” as in the word “may” and then make your lips into an “o” shape.
Vowels With Dots: Å, Ä, Ö
Å is pronounced like the English O in “or,” the Swedish Ä sounds almost like the word “air” in English, and Ö has a similar pronunciation to the [er] sound in the word “her.”
Ö is slightly more complicated for English speakers in terms of pronunciation. It is similar to the vowel in the British pronunciation of “bird”, “heard”, “curd” (IPA: /ɜː/), but with lips rounded. To say it, say /ɛ/ (as in “bet”) with your tongue but shape your lips as if saying “oo” in “boot”.
A glyph, U with umlaut, appears in the German alphabet. It represents the umlauted form of u, which results in [yː] when long and [ʏ] when short. The letter is collated together with U, or as UE.
The long 'oo' sound, [ū], is often spelled <u> or <o>. It is also often spelled with combinations of two vowel letters. When two vowel letters work together as a team to spell a single vowel sound, they are called a digraph.
"Õ" (uppercase), or "õ" (lowercase) is a composition of the Latin letter O with the diacritic mark tilde. This article contains phonetic transcriptions in the International Phonetic Alphabet (IPA).
But why do we pronounce one and once with a 'w'? It was originally pronounced like own in only, and in dialects 'un' - good 'un, young 'un. The /w/ sound was added to one and once in popular speech somewhere in the late Middle Ages between 1150 - 1476 (Middle English period) and first recorded in 1400.
