For many Spanish-speaking executives and professionals, the biggest hurdle in English pronunciation isn’t the grammar—it’s the vowels. In Spanish, the letter «i» is consistent, clear, and singular. English, however, demands a distinction that does not exist in the Spanish phonetic inventory: the difference between the long, tense /i:/ (as in sheep) and the short, relaxed /ɪ/ (as in ship).

Without the concept of vowel length or the relaxed tongue position, Spanish speakers often default to a middle-ground sound that can lead to embarrassing misunderstandings in a business context.

«The sheep is old.» vs. «The ship is old.»

The Physical Mechanics of the Sounds

Understanding how these sounds are physically formed is the first step toward correcting the habit:

The /i:/ sound (Long and tense): This is a high front vowel; that is, the tongue is positioned high in the front of the mouth. The muscles of the tongue and throat are tense. If the lips are drawn back slightly, the sound is pronounced with greater precision. Its duration is double (except when appearing at the end of words with a «y» like company or Mary, where it sounds short like in Spanish).
The /ɪ/ sound (Short and relaxed): This is also a high front vowel, but it is pronounced with the tongue in a slightly lower position than for /i:/. The muscles of the tongue, throat, and lips are entirely relaxed. It is a single-length or short sound.

Key Contrast Pairs

To train your ear and your vocal apparatus, directly compare these essential pairs:

Sheep (/i:/) ➔ Ship (/ɪ/)
Beet (/i:/) ➔ Bit (/ɪ/)
Leek / Leak (/i:/) ➔ Lick (/ɪ/)
Heat (/i:/) ➔ Hit (/ɪ/)

Practice Phrases in Professional and Everyday Contexts

Practice these sentences aloud to automate the transition between both sounds:

Sit on this seat.
She’s still asleep.
These shoes don’t fit my feet.
It’s easy to see the ships.
The sheep are in the ship.
They need an English dictionary.
