To make the /ɛ/ sound:
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. Problems with playback may be resolved by refreshing the page.
TL;DR: To pronounce the /aʊ/ sound correctly, connect the /ɑ/ sound to /ʊ/ with a smooth, gliding movement. Step-by-step pronunciation instructions: Mouth: First, open your mouth very wide for the /ɑ/ sound. Then glide into the /ʊ/, closing it partially.
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.
In this lesson, you'll learn how to pronounce the OH as in ROSE vowel sound. You hear this sound in words like “home,” “control,” and “appropriate.” You might think this sound is pretty easy and you've already got it just right.
The /ɪ/ vowel is a high-front sound. Your tongue should be positioned high in your mouth, and shifted toward the front. Your lips should be relaxed, and only slightly open. Vibrate your vocal cords with your mouth in this position.
They are different ways of representing the same diphthong phoneme in IPA, so yes, they are the same. They are associated with different dialects, though (/əʊ/ with British Englishes, /oʊ/ with American Englishes), so no, they're generally not pronounced the same.
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.
The open-mid front unrounded vowel, or low-mid 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 a Latinized variant of the Greek lowercase epsilon, ⟨ɛ⟩. Open-mid front unrounded vowel. ɛ
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/.)
Examples of the ɑ: Sound
art /ɑːt/ arm /ɑːm/ answer /ˈɑːnsə/ argue /ˈɑːgjuː/
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.
For the S sound, the tongue tip touches the back of the bottom front teeth. The front/middle part lifts a little bit. For the SH sound, the tongue tip lifts to the middle of the mouth.
/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.
The exact pronunciation of the vowel sound of ⟨ю⟩ in Russian depends also on the succeeding sound because of allophony. Before a soft consonant, it is [ʉ], the close central rounded vowel, as in 'rude'. Before a hard consonant or at the end of a word, the result is a back vowel [u], as in "new".
The sound /ʊ/ is a back, high, lax, rounded vowel. Spelling: “oo” – took, good. “u” – put, bush.
/ʃ/ is produced with a much more rounded mouth than /s/, and is the sound we make when we want people to be quiet. If you use your voice with that mouth position, you get the starting sound in "sheet" and the ending sound in "push".
