Handbook of the International Phonetic Association defines [ʊ] as a mid-centralized (lowered and centralized) close back rounded vowel (
The sound /ʊ/ is a back, high, lax, rounded vowel. Spelling: “oo” – took, good. “u” – put, bush.
In English, examples of rounded vowels are o in “note,” oo in “look,” and the u sound in “rule” and “boot”; w in “well” is an example of a rounded semivowel.
/ʊ/is a high, back, lax vowel. To make it, your tongue should be lifted high in the mouth (slightly lower than /u/), and shifted toward the back. Keep your lips relaxed and slightly open. Then, vibrate your vocal cords as you push air out of your mouth.
The vowel /ʊ/ is the short or lax vowel as in words like hook. Positionally, it is a back high vowel, which occurs in a few other languages.
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.
Pronunciation: The sound /ʃ/ is a voiceless, alveo-palatal, fricative consonant. Lightly press the middle of your tongue between your alveolar ridge and your soft palate. The sides of your tongue should lightly touch your back upper teeth.
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.
Vowel Sound / oʊ / as in "go" - American English Pronunciation.
The near-close front unrounded vowel, or near-high front unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɪ⟩, i.e. a small capital version of the Latin letter i.
Normally vowels which are back and not low are pronounced with the lips in a rounded position (e.g. [o] and [u]). Front and central vowels and back low vowels are normally pronounced with the lips unrounded (e.g. [i], [e], [a]).
Front rounded vowels are cross-linguistically relatively uncommon, but occur in a number of well-known languages, including French, German, Turkish and Mandarin. Lip rounding is produced by bringing the corners of the lips together and protruding them forward.
This vowel is a mid-front vowel. Position your tongue at mid-height in your mouth, and shift it toward the front. The muscles of your lips and mouth should be relaxed. Vibrate your vocal cords with your mouth in this position.
/ɔɪ/ is a diphthong, which is like a combination of two different vowel sounds. To begin, place your tongue at mid-low height in your mouth, shifted toward the back, to say /o/. Round your lips into an “o” shape as you do so.
/aʊ/ is a diphthong sound which means it is a combination of two vowel sounds that are pronounced within the same syllable. The aʊ sound is a combination of /æ/ and /ʊ/ or /u:/. Like vowels the diphthongs are all made through the mouth and are voiced which means that you vibrate your vocal chords to make the sound.
The trend, is that in all cases, the British IPA would use ɒ , while American would use ɑ . Now from my perspective, this is correct, Americans tend to elongate and turn it into more of an "aw" sound, while British English tends to keep it sharper.
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.
/ɒ/ is a short single sound made without the mouth moving. /əʊ/ is a diphthong -- a longer sound made of two sounds -- meaning that the mouth moves during production of the sound.
Sound 1: /tʃ/ Tip:To produce this sound, your tongue should touch the tooth ridge to stop air. Then, move your tongue behind the tooth ridge to release air. The sound /dʒ/ begins as a stop (with no air coming through the mouth) but then moves into a fricative (with some air released).
/ʧ/ is pronounced without your tongue moving and with more air released than with /t/. It is similar to the sound of a sneeze, and the air released should be able to move a piece of paper or be felt on your hand five centimetres in front of your mouth.
The close-mid central rounded vowel, or high-mid central rounded vowel, is a type of vowel sound. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɵ⟩, a lowercase barred letter o.
How to Produce /ɒ/? To produce it, drop the jaw just a little and round the lips, unlike the unrounded /ɑ/ sound. Push your lips together and make a short, voiced sound. As you can see in the picture, the mouth is slightly more open than the /æ/ sound and less rounded than when producing the /ɔ/ sound.
