Exercise 2-6: Consonant / Consonant Liai sons                                CD 2 Track 41 

I just didn't get the chance .  [I·jusdidn't·ge(t)the·chance.] I've been late twice.  [I'vbinla(t)twice.]

In the preceding examples you can  see that because  the ending [st] of just  and the beginning [d] of  didn't  are so near each other in the mouth, it's  not worth the effort to start the sound all over again, so they just flow in to each other.  You don't say I justə didn 't ə get ə the chance, but do say I just didn't ge(t) the chance.  In the same way, it's too much work to say  I'v ə beenə late ə twice,  so you say it almost as if  it were a single word, I' binla (t) twice.

The sound of TH is a special case. It is a floater between areas. The so und is sometimes created by the tongue popping out from betwee n the teeth and other times on  the back of the top teeth, combining with various letters to form a new  composite sound. For instance, [s] moves forward and the [th] moves back to meet at the mid-point between the two.  

Note Each of the categories in the drawing contains two labels—voiced and unvoiced. What does that mean ? Put your thumb and index fingers on your  throat and say [z]; you should feel a vibration from your throat in your fingers . If you whisper that same sound , you end up with [s] and you fee l that your fingers don't vibrate.  So, [z] is a voiced sound, [s], unvoi ced. The consonants in the two left columns are paired like that.
