How to Type in Vietnamese — VNI/Telex Input Guide
Vietnamese has the most complex tone/accent system among major languages typing in Latin script — 6 tones × multiple vowel variants = up to 18 forms per vowel. You can't put them all on a keyboard, so Vietnamese uses VNI or Telex input methods that generate diacritics from regular keystrokes.
Vietnamese tonal system
6 tones marked with diacritics:
- Level (no mark): a
- Falling (à): grave
- Rising (á): acute
- Falling-rising (ả): hook
- Tilde drop (ã): tilde
- Sharp falling (ạ): dot below
Plus vowel modifiers: ă, â, ê, ô, ơ, ư, đ. Combined with tones = many variants.
VNI input method
Uses numbers as tone markers after vowels:
- 1 = acute (á):
a1→ á - 2 = grave (à):
a2→ à - 3 = hook (ả):
a3→ ả - 4 = tilde (ã):
a4→ ã - 5 = dot below (ạ):
a5→ ạ - 6 = circumflex:
a6→ â - 7 = horn:
o7→ ơ - 8 = breve:
a8→ ă - 9 = stroke:
d9→ đ
Telex input method
Uses letter combinations:
- s = acute (á):
as→ á - f = grave (à):
af→ à - r = hook (ả):
ar→ ả - x = tilde (ã):
ax→ ã - j = dot below (ạ):
aj→ ạ - aa = â, ee = ê, oo = ô
- ow = ơ, uw = ư
- dd = đ
Telex is more popular among modern Vietnamese users (letters in home row positions).
QWERTY-VN layout
Standard QWERTY-US base. Real Vietnamese typing requires IME software (UniKey on Windows, GoTiengViet on Mac, built-in mobile). See QWERTY-VN layout deep-dive.

Common Vietnamese typing patterns
- tôi, bạn, anh, em — common pronouns
- xin chào, cảm ơn, xin lỗi — politeness
- Việt Nam, Hà Nội, Sài Gòn — proper nouns

Almost every Vietnamese word has at least one diacritic.
Touch typing tips
- Choose ONE input method (VNI or Telex) and stick with it
- Don't skip diacritics — Vietnamese requires them
- Practice common words with full diacritics from day 1
- Use OS-level IME for proper Vietnamese input
Target: 35-45 WPM in 6-8 weeks (slower than letter-based languages due to IME overhead).
Frequently Asked Questions
Why does Vietnamese need an IME?
Too many tone/vowel combinations to fit on a keyboard. IMEs generate them from base letter + modifier keys.
Is VNI or Telex faster?
Telex is slightly faster (letters in home row vs reaching number row). More common today.
Can I type Vietnamese without an IME?
Possible via Unicode code points — extremely slow. IME is essential.
What about Vietnamese on phones?
Mobile keyboards have built-in VNI/Telex. Long-press vowels for diacritic options.
Is Vietnamese typing slow?
Slower than English. Fluent typists reach 50-60 WPM vs English 70-80 WPM.
Are there other input methods?
VIQR (older), various proprietary methods. VNI and Telex dominate.
