Two sounds, one tongue position

English has two TH sounds. They use exactly the same mouth position; the only difference is your voice.

Sound	Examples	Voice
/θ/	think, three, bath, month	voiceless — only air
/ð/	this, the, mother, breathe	voiced — your throat buzzes

Put a hand on your throat. Say a long “ssss”, then a long “zzzz”. The second one buzzes. That buzz is the whole difference between /θ/ and /ð/.

Where the tongue goes

1. Relax your jaw and open your mouth slightly.
2. Put the tip of your tongue lightly between your teeth — just the tip, not the whole tongue.
3. Blow air gently over it. Do not press, and do not bite.

Hold a finger in front of your lips. If the tip of your tongue can almost touch it, you are doing it right.

The most common mistake is moving the tongue back to make the sound “cleaner”. The moment the tongue hides behind the teeth, you get /s/, /t/ or /f/ again.

The 30-second drill

Say each pair slowly, then fast. Feel the tongue move forward on the second word.

1. sink — think
2. sank — thank
3. tree — three
4. zen — then
5. day — they

Then read this sentence three times, a little faster each time:

I think this thing is worth three thousand.

Why a teacher may miss it — and an app will not

When you speak a whole sentence, a listener’s brain fills the gaps, so a missing TH is easy to overlook. HolosAccent scores every sound separately, so a think that came out as “sink” is flagged on the exact sound — /θ/ → /s/ — instead of just lowering an overall score.

Two minutes a day on TH words is usually enough to make the new tongue position automatic within a couple of weeks.
