TH Sound for Hindi Speakers
Master the interdental /θ/ and /ð/ sounds - a unique English challenge
Why TH is Difficult for Hindi Speakers
Hindi uses dental consonants where the tongue touches the back of the teeth (like /t̪/ and /d̪/), but English uses interdental consonants where the tongue is BETWEEN the teeth. Hindi speakers often:
- • Replace /θ/ with dental /t̪/: Tongue touching back of teeth instead of between
- • Replace /ð/ with dental /d̪/: Same issue with voicing
Hindi Dental /t̪/ Sound
Your tongue touches the BACK of your top teeth. This is a common sound in Hindi.
Example: "तारा" (star)
Tongue behind teeth
English /θ/ Sound
Your tongue is BETWEEN your upper and lower teeth. This is the crucial difference for English TH.
Example: "think"
Tongue sticks out between teeth
Step-by-Step Guide to Produce /θ/
Open Your Mouth Slightly
Relax your jaw and open your mouth a little, as if you're about to say a neutral vowel.
Place Your Tongue BETWEEN Your Teeth
This is the most important step. Gently let the tip of your tongue protrude slightly between your upper and lower front teeth. It should not touch the back of your teeth.
Blow Air Gently
Push a gentle stream of air between your tongue and your top teeth. You should hear a soft, breathy friction sound. For /ð/, add voice from your vocal cords.
Keep Your Tongue Relaxed
Avoid tensing your tongue. It should be flat and relaxed as it rests between your teeth.
Practice: Hindi Dental /t̪/ vs English /θ/
Train your mouth to make the distinction:
Exercise 1: Feel the Tongue Position
Hindi /t̪/: Say a Hindi word like "तारा" (star) and notice your tongue touching the back of your top teeth.
English /θ/: Now, try to say "think" with your tongue tip BETWEEN your teeth. Feel the difference.
Repeat this several times, focusing on the tongue's contact point.
Exercise 2: Mirror Practice
Look in a mirror and say these words:
- • "think" - you should see your tongue tip between your teeth
- • "thank" - same tongue position
- • "three" - same tongue position
Ensure your tongue is visible for the English TH sound.

Common Mistakes Hindi Speakers Make
-
❌ Mistake: Replacing /θ/ with dental /t̪/ (e.g., "tink" instead of "think")
Why: Your tongue is touching the back of your teeth, like in Hindi.
✓ Fix: Move your tongue forward so the tip is BETWEEN your teeth. -
❌ Mistake: Replacing /ð/ with dental /d̪/ (e.g., "dis" instead of "this")
Why: Similar to the /t̪/ mistake, but with voicing.
✓ Fix: Tongue between teeth + voice your vocal cords. -
❌ Mistake: Not sticking the tongue out enough
Why: The tongue is too far back, preventing the correct interdental friction.
✓ Fix: Exaggerate the tongue protrusion at first. You should see it clearly.
Tips for Hindi Speakers to Master TH
- 💡 Tip 1: Use a mirror! You MUST see your tongue tip between your teeth for English TH. This is the biggest difference from Hindi dental sounds.
- 💡 Tip 2: Practice the contrast between Hindi /t̪/ and English /θ/. Feel the tongue movement forward.
- 💡 Tip 3: Exaggerate the tongue protrusion at first. Make it very obvious that your tongue is between your teeth.
- 💡 Tip 4: Record yourself and compare with native speaker audio. Listen for the subtle difference in placement.
- 💡 Tip 5: Be patient and consistent. This requires retraining muscle memory from your native language.
