The sounds in "chip" and "jet"

Both of these two sounds is actually a combination of two different sounds. The "ch" sound like in "chip" is a combination of /t/ as in "tip" and "sh" like in "ship". The "j" sound in "jet" is a combination of /td/ as in "dip" and the sound in the middle of leisure and measure.

They are both made the same way in your mouth. The difference is that "ch" is made without using your voice, and "j" is made by using your voice.

To make these sounds, put your tongue on the roof of your mouth, right behind your teeth, then move your tongue back behind your teeth until you are making the "sh" or "measure" sound.

If you are having trouble making these sounds, try these tricks. To say "chip", practice saying "meet ship". Say it faster and faster, and then you will notice that it sounds like you are saying "me chip". If you are having problems with "jet", first, say the word "measure" several times. Now try to add a "d" in the middle of the word, so you are saying "meadsure". Try saying this fast. It will sounds as if you are saying "medjure". Now you've got it!

Watch videos for these sounds! In these video clips, notice how the speaker's mouth moves in a very similar way for both 'church' and 'judge' -- the difference in how she says them is with her voice. (These videos will launch a separate video viewer to play them. Make sure you have a plug-in for video clips.)

Now let's listen to some sounds!

The sound in "yet"

/j/

/j/, the sound at the begining of "yet", is made by putting your tongue very close to the top of your mouth, as if you are getting ready to say the vowel /i/. That is why this consonant sound is often pron ounced between certain vowel sounds.

Say the phrase "why he" quickly. Native speakers of American English would often pronounce this phrase as "whyje" (/waIji/). Even though it is not spelled that way, we pronounce a /j/ between the /a I/ and /i/ vowels.

Now let's listen to some sounds!

    /j/ sounds:
  • yet
  • you
  • he is (/hiyIz/)
  • why he (/waIji/)

The sound in "wit"

/w/

/w/ is an interesting sound, because you need to do two different things with your mouth. First of all, you need to make lips round, as if you are getting ready to kiss someone. Next, you need to put the back of your tongue close to the roof of your mouth, almost as if you are going to say g, but DON'T touch the top of your mouth. You must do both of these things at the same time. Use your voice. /w/ is a voiced sound.

Be careful that you do not confuse /w/ with /r/. When you say /w/, your tongue is further back in your mouth and the back of it is close to the top of your mouth. When you say /r/, your tongue is a little bit more towards the front of your mouth, and the tip of your tongue is pointed towards the top of your mouth.

Watch a video clip with the /w/ sound! (This video will launch a separate video viewer to play it. Make sure you have a plug-in for video clips.)

Now let's listen to some sounds!

The sound in "hat"

/h/

/h/ is basically the sound that you make by opening your mouth wide and blowing air.

Now let's listen to some sounds!

Word Final Fricatives - Voiced and Unvoiced

Many students of English have problems pronouncing the consonant sounds at the end of words. On this page, you can hear examples of /f/, /v/, "th" sounds /s/, /z/, "sh" , and the sound in the middle of "measure"

There is actually a small difference in how long we say the vowels before voiced and unvoiced sounds. Listen to these pairs of words or say them out loud. Which ones have the longer vowels?

Did you notice that the vowels are shorter in "leaf", "breath", "seas", and "rush"? These are the three unvoiced sounds. However, the unvoiced consonants themselves (f, s, sh) are longer than the voiced vowels. So, the difference is not just whether the sounds are voiced or unvoiced, but also how long they last.

The sounds in "git" and "kit"

/g/ /k/


The consonant sounds in "git" and "kit" are both made by putting the back of our tongue up against the roof on the back of our mouths to release a small puff of air.

If we make these sounds the same way, then what is the difference between them? The difference is not what we do with our mouths, but what we do with our voice.

When we make a /k/ sound, we do not use our voice; the sound is quiet. Put your hand on your throat and make the sound /k/. You should not feel any movement in your throat.

However, when we make a /g/ sound, we do use our voice. Put your hand on your throat and make the /g/ sound. Can you feel the vibrations? Another way to help you learn the difference between these two sounds is that /k/(the voiceless sound) makes a bigger puff of air. Put your hand in front of your mouth and make the /k/ sound. Feel the big puff of air. Now put your hand in front of your mouth again and make the /g/ sound (the voiced sound). Feel only a little puff of air? Good!

Now let's listen to some sounds!

"git" sounds:
"kit" sounds:

Voiced and Unvoiced

Many students of English have problems pronouncing the consonant sounds at the end of words. On this page, you can hear examples of /b/, /p/, /d/, /t/, /g/ and /k/.

There is actually a small difference in how long we say the vowels before voiced and unvoiced sounds. Listen to these pairs of words or say them out loud. Which ones have the longer vowels?

Did you notice that the vowels are shorter in "nap", "mat", and "knack"? These are the three unvoiced sounds. However, the unvoiced consonants themselves (p, t, k) are longer than the voiced vowels. So, the difference is not just whether the sounds are voiced or unvoiced, but also how long they last.

The sounds in "ship" and "measure"

The consonant sounds in "ship" and "measure" are both made by putting your teeth together, with your top teeth in from of your back teeth, and putting your tongue in the middle of your mouth, scrunched up towards the back of your mouth.

If we make these sounds the same way, then what is the difference between them? The difference is not what we do with our mouths, but what we do with our voice.

When we make a "sh" sound, we do not use our voice; the sound is quiet. Put your hand on your throat and make the sound in "ship". You should not feel any movement in your throat.
However, when we make a "zh" sound, we do use our voice. Put your hand on your throat and make the sound in "measure". Can you feel the vibrations?

There are not many words in English with the sound in "measure", and very few words with this sound at the beginning. This sound is mostly found in words that came into English from other languages in the middle or at the end of the word.

Now let's listen to some sounds!
