Do you ever mix up words like shoes and choose? You're not alone. The /ʃ/ (sh) and /tʃ/ (ch) sounds are closely related, and many English learners confuse them. The good news is that once you understand the key difference, telling them apart becomes much easier.
The /ʃ/ Sound: The "Silence" Sound
Think of the sound you make when you ask someone to be quiet: "Shhh!" That's the /ʃ/ sound. It is a continuous fricative, which means air flows smoothly through a narrow gap in your mouth without stopping.
How to make the /ʃ/ sound:
- Raise the front of your tongue toward the roof of your mouth, just behind the ridge, but don't touch it.
- Round your lips slightly, pushing them forward a little.
- Push air through the narrow gap between your tongue and the roof of your mouth.
- The air should flow out continuously, producing a smooth, hissing sound. You can hold this sound for as long as you have breath: "shhhhhh."
Your vocal cords do not vibrate for /ʃ/. It is a voiceless sound.
The /tʃ/ Sound: The "Sneeze" Sound
Now think of the sound you make when you sneeze: "Achoo!" That initial burst is close to the /tʃ/ sound. It is an affricate, which means it starts with a brief stop (like /t/) and then releases into a fricative (like /ʃ/).
How to make the /tʃ/ sound:
- Press the tip of your tongue firmly against the ridge behind your upper teeth, completely blocking the airflow.
- Build up a small amount of air pressure behind your tongue.
- Release your tongue quickly, letting the air burst out into the /ʃ/ position.
- The result is a short, explosive sound. You cannot hold /tʃ/ the way you can hold /ʃ/.
Like /ʃ/, the /tʃ/ sound is also voiceless.
The Key Difference: Continuous vs. Explosive
Here's the simplest way to remember:
- /ʃ/ (sh) is continuous. Air flows smoothly and you can stretch the sound out: "shhhhhh."
- /tʃ/ (ch) is explosive. It starts with a block and releases in a quick burst. You cannot stretch it.
Try this test: say the sound and try to hold it. If you can hold it, it's /ʃ/. If it comes out as a quick burst, it's /tʃ/.
Minimal Pairs: Train Your Ear
Minimal pairs are words that differ by only one sound. Practicing these will help you hear and produce the difference between /ʃ/ and /tʃ/ clearly.

Tips for Better Articulation
- Mirror test: Practice in front of a mirror. For both sounds, your lips should round slightly. The difference is what your tongue does: for /ʃ/, it hovers near the roof; for /tʃ/, it taps the ridge first.
- Hold test: Try to hold the sound. If you can sustain it ("shhhh"), you are making /ʃ/. If it only comes out as a quick burst, you are making /tʃ/.
- Slow down: When practicing /tʃ/, try saying /t/ followed by /ʃ/ slowly, then gradually speed up until it becomes one smooth motion.
- Pair practice: Say the minimal pairs above back to back ("sheep, cheap, sheep, cheap") to build muscle memory for switching between the two sounds.
- Record yourself: Use your phone to record yourself saying the practice words. Play it back and compare with a native speaker. This helps you catch mistakes you might not notice in real time.
With consistent practice, you will stop confusing shoes and choose in no time. Keep practicing and pay attention to how your tongue moves!
