1. Voiceless "th" (as in "thin", "think", "tooth")
* Place your tongue between your teeth, with the tip slightly behind your front teeth.
* Push air out from your mouth, making a hissing sound.
* Your vocal cords should not vibrate.
2. Voiced "th" (as in "this", "that", "other")
* Same tongue placement as above, but vibrate your vocal cords.
* This creates a softer, more breathy sound.
Practice Tip:
* Try saying "thin" and "this" repeatedly, focusing on the difference in your voice.
* Look in a mirror to ensure your tongue is positioned correctly.
Note: Some languages, like Spanish, do not have the "th" sound. If you are a non-native English speaker, it may take some practice to master this sound.
