/θ/ and /ð/ Sounds

Master the tricky TH sounds! Learn the difference between voiceless and voiced TH pronunciation.

🔤 The Two TH Sounds

English has two distinct TH sounds that are often confused. Master both to sound more natural!
/θ/
Voiceless TH
Like a "hiss" sound
Vocal cords do NOT vibrate
think, thank, mouth
/ð/
Voiced TH
Like a hum or vibration
Vocal cords DO vibrate
the, father, smooth

👄 How to Pronounce

Tongue Position
👄
Place your tongue tip between your teeth
Push air through the gap
Voiceless = just air
Voiced = air + vibration
⚠️ Common Problems

Voiceless /θ/: If you replace with /s/, "think" sounds like "sink"

Voiced /ð/: If you replace with /d/, "that" sounds like "dat"
