Sound /θ/

How to make the unvoiced TH sound

For the unvoiced TH, the tongue tip lightly touches or sits just behind the top front teeth while air flows over it, with the voice off. It is the TH in think and bath, not the one in this. TH is one of the later sounds to develop, often not mastered until age 6 or later, and substituting F is common along the way.

unvoiced TH sound questions

One is voiceless and one is voiced. Think, thumb, and bath use the quiet one. This, mother, and breathe use the buzzy one. Put a hand on the throat and only the second one vibrates.
