/tʃ/

The /tʃ/ sound in English is a voiceless post-alveolar affricate, which means it’s a sound made by stopping the airflow in the vocal tract (like a stop), and then releasing it so that the air travels along a groove in the middle of the tongue and over the sharp edge of the teeth (like a fricative). Here’s how you pronounce it:

• Position your tongue: For the /tʃ/ sound, your tongue should be raised so the front of your tongue is close to the roof of your mouth, just behind the alveolar ridge (the bumpy ridge behind your upper front teeth).
• Voicing: The /tʃ/ 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: Begin by blocking the airflow with your tongue, then release the blockage suddenly. The air should flow over the tongue and out of your mouth continuously after the blockage is released, producing the /tʃ/ sound.
