Consonant phonemes /ʒ/, /ʃ/

English has two fricative consonants that are produced in the post-alveolar or pre-palatal regions of the mouth: the fricative pair /ʒ/ and /ʃ/.

The voiced fricative /ʒ/ as in beige, also written as /ž/ in some texts that do not strictly follow the International Phonetic Alphabet.
The voiceless fricative /ʃ/ as in fish, also written as /š/.

In teaching pronunciation, these are often distinguished from each other, from the English /s/ and /z/ sounds, from the English palatal consonant phonemes /ʤ/, /ʧ/, and from post-alveolar or palatal consonants in the students' first language,

1 Linguistic description

Manner of articulation: Both sounds are fricatives (friction sounds) produced by directing the air flow between the tongue and the top of the oral cavity. More technically, it is a sibilant fricative, that is, it is produced by pushing the air stream along the grooved tongue surface (the tongue blade, or the front section of the tongue) creating a hissing-style high frequency noise due to air turbulence.
Place of articulation: Both sounds are palato-alveolar, i.e., with the tongue blade approaching an area ranging from behind the alveolar gum ridge to the pre-palatal area. In English, the tongue is apical, that is, the tongue blade is pointed up toward the alveolar/palatal region. Friction is created between the tongue tip (apex) plus tongue blade area and the palatal-alveolar area.
The /ʒ/ sound is voiced, i.e., produced with vibration of the vocal cords.
The /ʃ/ sound is voiceless, i.e, produced without vibration of the vocal cords

1.1 Cross-linguistic comparison

The voiced consonant /ʒ/ is fairly common in European and other languages, most notably in French, e.g., jour. The voiceless consonant /ʒ/ is fairly common in European and other languages, most notably in French, e.g., jour. In French, German, and Russian, the lips might be slightly more rounded for these sounds.

East Asian equivalents present some difficulties, as the equivalent or analogous sounds are produced differently and have different syllabic patterns. Chinese (Mandarin and other varieties), Japanese and Korean have alveolo-palatal fricatives, which are produced with the front tongue blade. More importantly, while the English sounds are apical, with the tongue blade and tip pointing up toward the alveolar-palatal area, in these East Asian languages, the tongue blade is flat, and friction is created between the flat tongue blade and the alveolar-palatal area. This tongue position is termed laminal, as opposed to apical. Examples:

The voiceless fricative /ɕ/ as in Mandarin 西安 Xī'ān, Korean 시 si poem and Japanese 塩 shio salt. This is also the same sound as the German ich.
The voiced fricative /ʑ/ is a variant - an allophone or a sound in some dialects - of Japanese and southern Chinese.

For East Asians, their sibilant fricative sounds are more syllabically restricted. In English, these sounds can occur anywhere in a word in principle - word-initially as in show, medially as in vision or fission, and word-finally as in fish. East Asians may need to learn to pronounce these word-finally without inserting an extra vowel. Koreans and Japanese have particular problems, as their sibilant fricatives do not occur word-finally in their languages without an extra end vowel. This is also related to the laminal pronunciation of the Korean and Japanese fricatives. Thus, their pronunciation of fish can sound like fishy or fish-uh with a flat tongue.

In Russian, the voiced and voiceless fricatives are fully palatal, with the tongue bent further back toward the central palatal area. Learners will need to bend the tongue slightly forward.

Chinese has another consonant series of palatal fricatives like the Russian sounds, in addition to the alveolar-palatal consonants. This includes a voiced fricative, which can also be rhotic or r-like in some environments.

1.2 Teaching /ʒ/ and /ʃ/ production

For those from a first language (L1) background from Europe and many other parts of the world, these sounds may not be so problematic. Some languages might have /ʃ/ but no /ʒ/, so learning to hear and produce /ʒ/ is simply a matter of pronouncing /ʃ/ and then vibrating the vocal cords. Students can place their hands on their throats to feel the vibration. They can begin with the voiceless - voiced contrast between /s/ and /z/ to learn how to vocalize another unvoiced consonant.

Students whose L1 has alveolar-palatal or fully palatal sounds instead will need to learn to adjust their tongue position, bringing it more forward or more back. East Asians need to learn to pronounce these sounds with an apical tongue pointing toward the top of the oral cavity instead of the flat-tongue pronunciation. They will also need to learn to pronounce final /ʒ/ and /ʃ/ without inserting an extra vowel or extra air flow at the end.

It should be noted that the voiced consonant /ʒ/ is less common in English. It occurs mainly in Latin words where an /s/ or other sound palatizes to a /ʒ/ in certain environments, e.g., decision, and in French loan words like beige. The /ʃ/ is much more common and probably deserves more priority and attention than /ʒ/.

2 Practice activities and materials

Minimal pairs, which contrast a target sound with a sound that is a separate phoneme, are typical starting points for production and practice activities, particularly comparing the following, depending on the learners' levels and L1 backgrounds.

/ʒ/ as in beige with /z/ as in bays
/ʒ/ as in beige with /ʤ/ as badge
/ʒ/ as in fusion with /ʃ/ as in fission
/ʃ/ as in shell with /s/ as in cell
/ʃ/ as in share with /ʧ/ as in chair

These contrasts should be shown with minimal pair contrasts in syllable-initial, consonant cluster, medial, and final position. For more on types of minimal pairs activities to train listeners to discern and produce sounds, see the following.

2.1 Tongue twisters

Sally sells seashells by the seashore. So if Sally sells seashells by the seashore, where are the seashells that Sally sells?
I wish to wish the wish you wish to wish, but if you wish the wish the witch wishes, I won’t wish the wish you wish to wish.
Ah shucks, six stick shifts stuck shut!
The sixth sick sheik’s sixth sheep’s sick.
She sells cshs by the C shore. [programmer’s lingo: csh = c-shell]
I think she should sit.

And an odd poem:

Moses supposes his toeses are roses,
but Moses supposes erroneously.
For Moses, he knowses his toeses aren't roses,
as Moses supposes his toeses to be.^[1]

2.2 Word-final position

Watch out for these sounds at the end of words. There should not be an extra syllable.
