Ship or sheep? The two English "i" vowels
English has two vowels where many languages have one. The vowel in ship is short and loose, with a relaxed mouth. The vowel in sheep is long and tight, with the tongue high and the lips spread. They are different words, so this pair is worth real practice time.
The difference is not just length
Many textbooks call these the "short i" and the "long e", which suggests you only need to hold one of them longer. Length is part of it, but it is not the main part, and learners who only stretch the vowel still sound wrong.
The real difference is tension and tongue height. In sheep, the tongue is high and pushed forward, the muscles are tight, and the lips spread as if you were smiling. In ship, the tongue drops slightly, everything relaxes, and the lips do almost nothing.
A useful way to feel it: say the sheep vowel and hold it, then let your whole mouth go lazy without moving it much. The sound falls into the ship vowel. That drop from tight to loose is the contrast.
Why it disappears
If your first language has one vowel in this region, your ear puts both English vowels in the same box. You then produce one sound for both, usually somewhere in the middle, and native listeners have to guess from context.
The guessing usually works, but not always, and the pairs are common: ship and sheep, sit and seat, bit and beat, live and leave, this and these, fill and feel. "I want to leave" and "I want to live" are different plans.
Spelling adds confusion. The tight vowel is written many ways — ee in see, ea in eat, ie in piece, e in these, y at the end of happy and city, and even i in machine. The loose vowel is usually written i, but also y in gym and system, and ui in build. You cannot rely on the letters. You have to learn the sound with the word.
How to make each one
For the tight vowel in sheep: push your tongue high and forward, close to the roof of your mouth, and spread your lips wide as if smiling. Keep the muscles firm. Hold it — it should feel slightly tense, and it should be easy to make it long.
For the loose vowel in ship: start from the sheep vowel, then relax everything. Let your tongue fall a little, let your lips stop smiling, and make the sound short. It should feel effortless and slightly unfocused.
A physical check with your hand: put a finger at the corner of your mouth. When you say sheep, your lips pull back and your finger feels the corner move. When you say ship, it barely moves.
Now practice the switch. Say sheep, ship, sheep, ship, ten times, slowly. Feel the mouth tighten and relax. That switch is the skill.
Words to practice
Loose vowel: sit, big, give, this, will, six, dinner.
Tight vowel: see, eat, need, these, three, please, easy.
Pairs, said one after the other: ship and sheep, sit and seat, bit and beat, live and leave, fill and feel, is and ease.
Then a sentence with both, said slowly: "This is a big list of easy things to eat." Check each vowel as you go — tight or loose.
One more useful group: the y at the end of words like happy, city and easy uses the tight vowel, even though it is written with a single letter. Say "happy city" and make both endings tight.
And watch out for the very common short words that use the loose vowel: is, it, in, this, will, if. They appear in almost every sentence you say, so getting them relaxed and short does more for your rhythm than any single long word.
What to listen for
Listen for effort. The tight vowel should feel like your mouth is doing work. The loose one should feel like it is doing nothing. If both feel the same, you are making one vowel twice.
Listen for length as a clue, but not as the goal. If you only stretch the loose vowel, you get a long, relaxed sound that is still not the sheep vowel.
Record both words and play them back to a friend without telling them which is which. If they cannot tell, keep going.
And use scoring where it helps. TonePerfect scores each sound inside the word you record, so you can see which of the two vowels is weaker for you and practice that one, rather than practicing both equally when only one is the problem.

Questions
Is the difference just that one is longer?+
No. Length is a clue, not the cause. The sheep vowel is made with a higher, more forward tongue and spread, tense lips. The ship vowel is lower and relaxed. If you only add length, the sound is still not right.
Which spelling goes with which sound?+
There is no reliable rule. The tight vowel appears as ee, ea, ie, e_e, y at the end of a word, and sometimes i as in machine. The loose vowel is usually i, but also y in gym and ui in build. Learn the sound together with the word.
Are other English vowel pairs like this?+
Yes. The same tight-versus-loose idea appears in full and fool, and English also separates vowels in cat, cut and bed that many languages merge. The lips, the jaw and how relaxed the vowel is do most of the work.
What if listeners understand me anyway?+
They often will, from context. But context costs the listener effort, and some pairs — live and leave, sit and seat — change the meaning of a sentence completely. It is a good investment because so many common words are involved.
