This is the “Sounds American” channel.

In this video we’re going to talk about the American consonant sound /θ/,

You can also hear this sound in words like

We’ll be using a special phonetic symbol - /θ/ - for this sound.

The English /θ/ sound occurs in very few world languages,

so it’s unfamiliar to the majority of non-native speakers.

Many non-native speakers often distort it or replace it with more familiar sounds,

Fortunately, this sound is not that hard to make.

Once you learn how to do it, it’s just a matter of practice.

So, let’s find out how to make the /θ/ sound.

This sound is all about the tip of your tongue.

Slightly open your mouth and put the tip of your tongue between your front teeth.

Note that the tip of your tongue may gently touch the bottom of your upper front teeth.

The stream of air should flow between your upper teeth and your tongue.

Note that the /θ/ is a voiceless fricative sound.

This means that it’s made from friction in the stream of air,

that people make when pronouncing the /θ/ sound:

Keeping the mouth closed or “biting” the bottom lip.

The /θ/ gets distorted and sounds more like the /f/.

Make sure your mouth is slightly open and that your upper teeth don’t touch your lower lip.

or pressing the tongue against the upper front teeth.

This way you’ll make a sound in between the /s/, /z/ and the /θ/.

Put the tip of your tongue between your upper and bottom front teeth.

Stopping the airflow with the tip of the tongue.

The /θ/ gets distorted and sounds more like /t/ or /d/.

/θ/ is a continuous sound; so keep the airstream flowing.

You should be able to stretch out the /θ/.

Now, let’s practice the /θ/ sound in some words.

You’ll see a word on the screen and hear its pronunciation.

You’ll have a few seconds to pronounce the word.

and try to practice as many words as possible.

Let’s pause for a second and check on how you’re making the /θ/ sound.

The tip of your tongue should be between your front teeth.

The sound is made from friction in the stream of air

flowing between your tongue and the teeth.

Did you know that the combination of the letters “th”

the voiceless consonant sound /θ/, as in the word “think,”

and the voiced consonant sound /ð/, as in the word “there”?

Here’s how you can check which sound to use:

“th” sounds as /θ/ at the beginning or at the end of the stem of content words.

For example, “theater,” or “health.”

“th” sounds as /ð/ at the beginning of function words.

We’ll talk more about the voiced /ð/ sound in one of our future videos.
