Modern Iranian Persian has six vowel phonemes. This guide writes them a, e, o, â, i, u: three historically short vowels and three historically long vowels. The practical distinction today is primarily one of quality—where the tongue and lips are—not a stopwatch rule that lets you turn a into â merely by holding it longer.
English speakers must also separate sound from spelling. Persian normally omits a, e, o in ordinary text, whereas â, i, u usually have a visible letter. The fully marked spokenForm below exposes every intended vowel for audio; the displayed Persian remains natural, unpointed writing. See vowel signs for learning and TTS for the marks themselves.
The six-vowel map
| Guide spelling | Approximate IPA | Articulation | Example | Ordinary spelling cue |
|---|---|---|---|---|
| a | /æ/ | front and open, like a clear North American cat vowel | سر — sar, “head” | usually unwritten |
| e | /e/ | front and mid, without English’s final glide | دل — del, “heart” | usually unwritten |
| o | /o/ | back, mid, and rounded; keep it pure | گل — gol, “flower” | usually unwritten |
| â | /ɒː ~ ɑː/ | low and back; not English cat | باد — bâd, “wind” | ا or initial آ |
| i | /iː/ | high and front, like the steady vowel in machine | دیر — dir, “late” | usually ی |
| u | /uː/ | high, back, and rounded, like a pure oo | دور — dur, “far” | usually و |
The IPA values describe educated Iranian pronunciation, not Dari or Tajik. Actual duration varies with stress, syllable structure, and speaking rate. The labels “short” and “long” remain useful because they explain the spelling and older poetry, but many modern analyses treat vowel quality as the dependable lexical contrast.
سرم درد میکند.
saram dard mi-konad.
My head hurts.
باد سرد شده است.
bâd sard shode ast.
The wind has turned cold.
The pair سر / باد makes the most important beginner contrast: a is front, while â is back. English spelling is actively unhelpful here because English a can represent either neighborhood depending on the word.
Keep e and o pure
English mid vowels often glide: many speakers pronounce day approximately as dey and go approximately as gow. Persian e and o are normally monophthongs. Stop at the vowel instead of sliding toward y or w.
دلش خیلی گرفته است.
del-ash kheyli gerefte ast.
He/She is feeling very down.
گلها را روی میز بگذار.
gol-hâ râ ru-ye miz begozâr.
Put the flowers on the table.
این کفش برای من تنگ است.
in kafsh barâ-ye man tang ast.
These shoes are tight on me.
Notice that دل، گل، تنگ do not show their short vowels. This does not mean that a reader inserts any convenient vowel. Each word has a learned pronunciation, just as English readers memorize the vowel of blood despite its spelling.
i and u are steady high vowels
Persian i is not the lax vowel of English sit, and u is not the vowel of book for most English speakers. Keep both high and steady. Their letters, ی and و, can also serve as consonants or participate in diphthongs, so a visible letter is a strong clue but not a complete pronunciation algorithm.
دیر رسیدم، ببخشید.
dir residam, bebakhshid.
I arrived late; sorry.
دوستم هنوز خواب است.
dust-am hanuz khâb ast.
My friend is still asleep.
چای روی میز بود.
chây ru-ye miz bud.
The tea was on the table.
The written forms دوست and بود both contain و for u, but روی contains و for u and ی for the glide y before ezafe. The dedicated pages on vâv and ye develop these choices.
Three layers: spelling, careful reading, conversation
A written word is not a narrow phonetic score. In (careful-spoken) standard Persian, readers pronounce the lexical vowels and grammatical material represented by the formal sentence. Educated Tehran conversation (informal; regional: Tehran) regularly changes some vowels and reduces whole forms; those changes are systematic, not sloppy versions of the careful line.
نان را آوردهام.
nân râ âvarde-am.
I have brought the bread. (careful-spoken standard)
نون رو آوردم.
nun ro âvardam.
I brought the bread. (informal; regional: Tehran)
Here نان nân becomes نون nun, را râ becomes رو ro, and the perfect is replaced by the conversationally natural آوردم. Do not mix one reduction into an otherwise formal reading by accident. For the conditioning of â → u, use Tehran vowel shifts.
Common Mistakes
1. Giving a an English back vowel
❌ سر
sâr
Incorrect — this says sar ‘head,’ with the short front vowel a.
✅ سر
sar
head
2. Turning â into the vowel of English cat
❌ باد
bad
Incorrect — باد has the low back vowel â; bad is the pronunciation of بد ‘bad.’
✅ باد
bâd
wind
3. Adding English glides to e and o
❌ دل و گل
deyl-o gow-l
Incorrect — e and o are normally steady vowels, not English-style diphthongs.
✅ دل و گل
del va gol
heart and flower
4. Reading only the visible consonants
❌ من کتاب دارم.
mn ktâb dârm
Incorrect — ordinary spelling omits short vowels, but speech does not.
✅ من کتاب دارم.
man ketâb dâram.
I have a book.
5. Replacing Persian i with e
❌ شیر سرد است.
sher sard ast
Incorrect — شیر begins with the high vowel i, not e.
✅ شیر سرد است.
shir sard ast.
The milk is cold.
Key Takeaways
Persian has six vowels: a, e, o, â, i, u. Treat their qualities as lexical contrasts, keep e/o/i/u free of English-style glides, and remember that ordinary spelling usually hides the short series. Finally, keep the written form, its careful reading, and a Tehran conversational realization in separate layers.
