The two consonant sounds we're targeting in this lecture are the sounds // as
in 'joke' and // as in 'choke'. So these two
sounds use the same part of the mouth as
we've seen before. The difference is one
is voiced one is unvoiced as we've also
seen before. The first sound // // look at the shape of my mouth // the
lips are coming out again //. Not
exactly rounded but they're being pushed
out // // joke. And when you make
the sound, notice what's happening inside
your mouth with your tongue. // // So your tongue, first of all, is
pushing up and blocking air. Then suddenly your tongue is pulling
down and releasing the burst of air. That's how this sound is made.
// // so you're building up air
pressure and then suddenly the tongue
drops and the pressure is released. // And this sound is voiced //
Joke //. The second sound uses exactly
the same process // // but it's unvoiced.
So the lips are the same shape, exactly
the same //. Can you see that? And the tongue
is also pushed up, building air pressure,
then suddenly it's dropped to release
the pressure // choke //.
But it's unvoiced. Test it for
yourself // //. There's no voice. That's
the main difference between the two. So
remember the shape of the lips. They
protrude out and the tongue is first
pushed up towards the front of the mouth, then you suddenly pull the tongue down to
release the pressure. Now let's look at the target sound
practice for these sounds. Let's look at
the // sound first.
Listen, repeat after me. As always, notice the spelling. Joe. Jeep. George. Ridge.
Edge. Dangerous.
Village. Large. Juice. Now let's look at
the second sound //
Remember the same process, except
this is unvoiced. Don't use the
vocal cords when producing the sound //. So listen, repeat after me once more.
Chip.
Chair. Chicken. Champion. Kitchen. Teacher.
Watch. Catch. Chess.
Very very well done. If you don't
have these particular sounds in your
language, remember to go back, practice
the exercises again until you really
start to master the sounds. Now let's
look at the minimal pairs for these two
sounds. On the left we have // and on
the right we have //. Remember the left
sounds are voiced, the ones on the right
are unvoiced. Let's begin.
Listen to the pairs and repeat. Jane, chain. Joke, choke.
Jill, chill. Ridge, rich. Edge, etch. Jeep, cheap.
Well done. Now let's look at the
target sounds in use in a sentence so we
can practice it when we're talking and
using other words together. So sentence
one we're focusing on the // sound, the
voiced sound. Jack gave Jane a large jug
of orange juice.
Sentence two we're focusing on the
unvoiced sound //. Charlie is the chess
champion of China. And sentence three a mix of the two sounds. This French cheese is
just amazing, and this Belgian chocolate
is gorgeous. OK, well done. Don't forget to
look at the video of the close-up of my
mouth
so you can see the shape, so that
you can produce the sounds much more
clearly.
