The consonant /dʒ/ is a voiced, alveo-palatal, affricate consonant. Press the middle of your tongue between your alveolar ridge and your soft palate. Quickly move your tongue downward while forcefully pushing air out. The air in your mouth should stop before it is released.
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.
The ʤ sound is a sound from the 'Consonants Pairs' group and it is called the 'Voiced palato-alveolar affricate'.
The consonant clusters /tj/ and /dj/ were very common in RP, occurring in words like situation, perpetual, tune, Tuesday, and due, during, education, gradual. Over time, there's been a tendency for such two-consonant clusters to coalesce into the single affricate consonants /tʃ/ and /dʒ/.
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 voiceless palato-alveolar sibilant affricate or voiceless domed postalveolar sibilant affricate is a type of consonantal sound used in some spoken languages. The sound is transcribed in the International Phonetic Alphabet with ⟨t͡ʃ ⟩, ⟨t͜ʃ ⟩ ⟨tʃ ⟩ (formerly the ligature ⟨ʧ ⟩), or, in broad transcription, ⟨c⟩.
It is a sound from the 'Consonants Pairs' group and it is called 'Voiceless palato- alveolar affricate'.
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.
What are affricates? The English affricates, the 'ch sound' /ʧ/ and 'j sound' /ʤ/ are two-part consonant sounds. They begin by fully stopping the air from leaving the vocal tract (similar to a stop sound), then releasing it through a constricted opening. (similar to a fricative sound).
In Received Pronunciation and in General American, the IPA phonetic symbol /dʒ/ corresponds to the initial consonant sound in words like "job", and "jet" and the final one in "page" and "change". /dʒ/ is a voiced consonant; its unvoiced counterpart is IPA phoneme /tʃ/.
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.
With /tʃ/ the air is released suddenly like a sneeze, making it almost impossible to extended the sound for any length of time. In contrast, you can extended /ʃ/ virtually as long as you like, as people do when they really want someone to be quiet.
Affricates are a mixture between plosives and fricatives. There are two of them in English: /ʧ/ and /ʤ/.
English has two affricate phonemes, /t͡ʃ/ and /d͡ʒ/, often spelled ch and j, respectively.
Its place of articulation is palato-alveolar, that is, domed (partially palatalized) postalveolar, which means it is articulated with the blade of the tongue behind the alveolar ridge, and the front of the tongue bunched up ("domed") at the palate.
The /ʤ/ is a sound from the 'Consonants Pairs' group and it is called the 'Voiced palato- alveolar affricate'.
The English affricate sounds are: /tʃ/ – “chick” and “match” – air is blocked with tongue just beyond the alveolar ridge (post-alveolar), then released as a fricative.
The /ŋ/ phoneme is, made through the nose rather than the mouth and it is Voiced, which means you use your vocal cords, but it is defined by the position of your tongue, and is made with the flow of air through the mouth completely blocked.
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.
The sibilant fricative consonants /s/ and /ʃ/ are produced with high-intensity and spectrally distinct aperiodic energy that is sensitive to the shape, placement, and movement of oral structures.
initial: chair - share; cheap - sheep; cheat - sheet; cheese - she's; chew - shoe; chews/choose - shoes; chip - ship; chop - shop; final: catch - cash/cache; match - mash; watch - wash; which/witch - wish.
The sounds /tʃ/ and /ʃ/ are both voiceless, alveo-palatal consonants. However, /tʃ/ is an affricate while /ʃ/ is a fricative. When you pronounce /tʃ/, the air in your mouth should stop (like a /t/) before it is released (like a /ʃ/).
