30-Day Challenge, Day 23

Today in the 30-Day Challenge we talked about American TH.  You can use the playlist below to help you work on your TH sounds.

For most people, accent errors on TH result from incorrect placement and manner of articulation.
Your tongue should rest gently between your teeth, not behind them or pushing against them.
The air should flow and there should be a noisy friction sound.  If you can't hold your th sound, you probably need to move your tongue and make sure that you are not blocking the air from flowing.
Use a mirror to help you see where you are placing your tongue as you try your TH sounds.

Practice on common words.  Voiced TH /ð/: 
them
the
this
those
there
Voiceless TH /θ/:
with
both
teeth
think
three

If words are too difficult at first., try syllables:

the thee thoo they thah though

eeth ooth ahth ehth ith oth

When you are comfortable using the American TH sound in words, move on to repeated phrase practice, for example:
those people, those shoes, those things, those words, etc.
with me, with him, with them, with the car, with the group, etc.
