/ʃ/

The /ʃ/ sound in English is a voiceless post-alveolar fricative, which means it’s a sound made by creating friction between the tongue and the area just behind the alveolar ridge (the bumpy ridge behind your upper front teeth), without vocal cord vibration. Here’s how you pronounce it:

• Position your tongue: For the /ʃ/ sound, your tongue should be close to the post-alveolar area, just behind the alveolar ridge. The tip of your tongue should be lowered just enough so that air can flow above it and out of your mouth.
• Voicing: The /ʃ/ sound is a voiceless consonant, meaning your vocal cords do not vibrate when you produce this sound. You should not feel a vibration if you lightly touch the front of your throat while saying the sound.
• Release the sound: As your tongue is positioned close to the post-alveolar area, direct a stream of air over the tongue and out of your mouth. The air should flow continuously, creating a hissing sound (like the sound of the wind or the sea).
