The open back rounded vowel, or low back rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the
To make this sound, the corners of the lips come in, pushing the lips away from the face. The middle part of the tongue lifts towards the roof of the mouth in the middle. The front of the tongue hangs down, but it's drawn back a bit. So, it's not touching anything.
The ʤ sound is a sound from the 'Consonants Pairs' group and it is called the 'Voiced palato-alveolar affricate'.
These are both low, tense vowels. However, /ɔ/ is a back, rounded vowel and /ɑ/ is a central, unrounded vowel. When you pronounce /ɔ/, your lips should form a circle. Note: Many American English speakers do not distinguish between these two vowels.
The biggest difference between these two sounds is that /ɒ/ is a short vowel and /ɔ:/ is a long one. The mouth position is also slightly different, with the mouth in /ɔ:/ being slightly tighter and more rounded.
Some Ways of Spelling the /ɒ/ Sound
o, as in: log, option, odd, shock, knob, off, God, sod, rod, don, pot, cot, etc. a, as in: watch, yacht, waddle, was, want, etc.
The sound /ʊ/ is a back, high, lax, rounded vowel. Spelling: “oo” – took, good. “u” – put, bush.
To make the /ɑ/ sound:
The /ɑ/ vowel is a low-back sound. Your tongue should be positioned low in your mouth, and shifted toward the back. Your mouth should be open wider than /ʌ/ or /o/. Vibrate your vocal cords and push air from your mouth.
So thus /ɑ/ would be a better choice in North America.
Across the pond, Received Pronunciation British and other dialects don't merge "father" and "bother" vowels like that, thus you get /ɒ/ to accommodate (by the way, /ɒ/ is the rounded version of /ɑ/.)
It is similar to the /æ/ sound, but the two little dots mean that it is a longer sounds. /ɑ:/ not /æ/. To produce the sound put your tongue low and at the back of your mouth, then make a long voiced sound with you mouth open.
These two are pronounced with exactly the same mouth position but /dʒ/ uses the voice, whereas /tʃ/ is just a sudden puff of air similar to a sneeze.
Both sounds are made by pushing air between the lower teeth and the roof of the mouth, but dʒ begins with a brief "d" sound, and ʒ does not. The two sounds are similar, but the initial "d" in dʒ makes it a sharper sound.
/ɜː/ sound
This is the sound of the 'ir' in 'bird' and the 'or' in 'word'.
Minimal Pair /ɑ:/ and /ɜ:/
Both sounds are long single sounds but the mouth position is different, with /ɑ:/ having a much wider open mouth position. This is why your doctor asks you to say this sound to show him or her inside your mouth. /ɜ:/ is much more like the sound people make when they are disgusted.
/ɪə/ sound
The diphthong actually sounds like /iː/ + /ə/. To make this sound, say /iː/, then move your tongue back and down and your lips less wide to make the /ə/ sound. A common problem for students is the difference between 'beer' and 'bear'.
The /ʃ/ sound is one of the nine fricative consonant sounds in American English. Note for geeks: the /ʃ/ sound is a palatal, voiceless, fricative consonant.
It is a Vowel sound and it's technical name is the 'Open back rounded vowel'.
The /əʊ/ symbol is made up of the short vowel sounds /ə/ and /ʊ/, meaning your mouth moves from the totally relaxed or slack mouth position of /ə/ to the rounded position of /ʊ/ while the /əʊ/ sound is made.
The sound /ɑ/ is a low, central, tense vowel. Lower your jaw and tongue. Your lips should be very open but not wide. Breathe out to pronounce the vowel.
The ʒ sound is from the 'Consonants Pairs' group and it is called the 'Voiced palato-alveolar sibilant'. This means that you create friction through clenched teeth by directing air flow through a narrow channel formed along the middle of the tongue.
It is a short sound. The spelling of /ʊ/ is sometimes 'u'; eg. 'put' /pʊt/, and sometimes 'oo'; eg. 'cook' /kʊk/.
The letter Ʊ (minuscule: ʊ), called horseshoe or sometimes bucket, inverted omega or latin upsilon, is a letter of the International Phonetic Alphabet used to transcribe a near-close near-back rounded vowel.
