The sounds in English

There are actually two different "th" sounds in English, but they are very similar. Both "th" sounds are made putting your tongue between your teeth so that the tip of your tongue is touching the tips of your top teeth. Now you can make a "th" sound by blowing are through your teeth. You can check to see if you are doing it correctly by using a mirror. You should be able to see your tongue when you say words such as "this", "the", and "that". If cannot see your tongue, yo u may be putting your tongue behind your top teeth instead of touching the tips of your top teeth.

If you put your tongue behind your top teeth, you will make a /d/ or /t/sound instead of a "th" sound. If it sounds like you are making an /s/ or /z/ sound, it is also because your tongue is behind your teeth. Make sure you are touching your teeth with your tongue!

Watch where the tongue is in these video clips. Can you see it between the teeth? (These videos will launch a separate video viewer to play them. Make sure you have a plug-in for video clips.)

  • 'that' close up video (500 k MPEG file)

    There is a difference, however, in the "th" sound in "the" and "breathe" and the sound in "thigh" and "breath". What is the difference?

    In "the" and "breathe", we use our voice when we make the "th" sound. Try to make a "th" sound using your voice. If you put your hand on your throat, you should feel the vibration.

    The sound in "thigh" and "breath" is made without using our voice. If you put your hand on your throat when you are making this sound, you will not feel anything moving.

    Now let's listen to some sounds!

    "thy" sounds:

    "thigh" sounds:

Nasal sounds

/m/ /n/ and "ng"

The beginning sounds in "mitt" and "knit", as well as the sound at the end of "bring", are called "nasals". That is because when we makes these sounds, the air goes out of our nose instead of our mouths.


The first sound, /m/, is made by closing your mouth. Now use your voice to make a sound. That is the sound /m/. Try holding your nose and making this sound. You can't do it. You need for the air to go out your nose in order to make this sound.

Here is a video clip with the /m/ sound. Compare this clip of someone saying 'mom' to the 'pop' clip on the b/p page. Notice how both sounds are made with the lips. BUT when the speaker says 'mom' she doesn't open her mouth again afterwards, but she does when she says 'pop.' Why? For /m/, you only need to close your mouth. For /p/, you need to close your mouth and then open it again to release that puff of air that makes the /p/. (These videos will launch a separate video viewer to play them. Make sure you have a plug-in for video clips.)

The second sound, /n/, is made by putting the tip of your tongue on the roof of your mouth, right behind your teeth, like you do when you make /d/ or /t/. Now use your voice to make a sound (don't move your tongue!). Be careful that you do not say /l/ instead of /n/. You can check by holding your nose. If you can make the sound and hold your nose, you are saying /l/, if you can't then you are saying /n/.

The sound at the end of "bring", the "ng" sound is actually one sound even though it is written with two letters. To make this sound, put your tongue up against the roof of the back of your mouth, as if you are going to say /k/ or /g/. Now, make a sound using your voice. This is "ng".
In English, the "ng" sound is only found at the end of syllables. It cannot start a word.

Now let's listen to some sounds!

The sounds in "bat" and "pat"

/b/ & /p/

The consonant sounds in "bat" and "pat" are both made by putting our two lips together and then opening them to release a small puff of air.

In these two video clips, you can see the woman saying the words "Pop" and "Bob." Notice

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

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

Watch videos of these sounds! In these video clips, notice how the speaker puts her lips together at the beginning and end of the words. In fact, notice that her lips move in a very similar way for both 'Pop' and 'Bob' -- 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.)

Reduced Vowel Sounds

In English, we give some syllables more stress than others. That means that some syllables are louder, longer, and clearer than others. Syllables that are unstressed are shorter, softer, and less clear. In fact, there are o nly TWO reduced vowel sounds in English. These are the "Schwa" sound and the "barred i" sound.

The "barred i" is like a really short /I/ sound.
The "schwa" is like a really short vowel made in the center of your mouth.

Now let's listen to some sounds!

The sounds in "oy!", "how" and "height"


These three vowel sounds are all diphthongs. This means they are actually two vowel sounds that slur together. Notice your mouth move when you say these sounds. Now compare that to "he". When you said "he", you can say the vowel sounds for a long time without moving your mouth!

Now let's listen to some sounds!

Here are some video clips!

Notice how the jaw moves, showing the movement from one vowel sounds to the second. (These videos will launch a separate video viewer to play them. Make sure you have a plug-in for video clips.)
