Hebrew Nikud (ניקוד) Reference
A reference guide for adding selective nikud to Hebrew text. Designed for AI agents that need accurate pronunciation hints (e.g., for TTS).
Golden Rule
Only add nikud when you're 100% certain it's correct. Wrong nikud is worse than no nikud — the TTS model will read your mistake literally instead of guessing correctly from context.
When to Add Nikud
- Ambiguous consonants (dagesh in בכ"פ)
- Gender-specific suffixes
- Homographs (same spelling, different pronunciation)
- Foreign names and loanwords
- Stress placement that changes meaning
When in doubt — don't nikud. Let the TTS model guess from context.
1. Vowel Symbols Reference
| Symbol | Name | Sound | Example |
|---|---|---|---|
| ַ | פַּתָח (Patach) | a | כַּלְבּ (kalb) |
| ָ | קָמָץ (Kamatz) | a (sometimes o) | שָׁלוֹם (shalom) |
| ֶ | סֶגוֹל (Segol) | e | מֶלֶךְ (melekh) |
| ֵ | צֵרֵי (Tzere) | e | לֵב (lev) |
| ִ | חִירִיק (Hiriq) | i | סִפֵּר (siper) |
| ֹ | חוֹלָם (Holam) | o | כֹּל (kol) |
| וֹ | חוֹלָם מָלֵא | o | שׁוֹמֵר (shomer) |
| ֻ | קֻבּוּץ (Kubutz) | u | קֻבּוּץ (kubutz) |
| וּ | שׁוּרוּק (Shuruk) | u | סוּס (sus) |
| ְ | שְׁוָא (Shva) | silent or e | זְמַן (zman) |
| ֲ | חֲטַף פַּתַח | short a | חֲלוֹם (khalom) |
| ֱ | חֲטַף סֶגוֹל | short e | נֶאֱמָן (ne'eman) |
| ֳ | חֲטַף קָמָץ | short o | צׇהֳרַיִם (tzohorayim) |
Shva Rules (שְׁוָא)
- Start of word → vocal (na): בְּרֵאשִׁית (bereshit)
- End of word → silent (nach): כָּתַבְתְּ (katavt)
- Two consecutive → first silent, second vocal: יִשְׁמְרוּ (yishmeru)
- After long vowel → vocal: כּוֹתְבִים (kotvim)
- After short vowel → silent: מַלְכָּה (malka)
2. Dagesh (דגש) — Hard vs Soft Consonants
Begedkefet (בגדכפ"ת)
Six letters historically changed sound with dagesh. In modern Hebrew, only three still have audible differences:
| Letter | With dagesh (hard) | Without dagesh (soft) | Audible in modern Hebrew? |
|---|---|---|---|
| בּ | B | V (ב) | ✅ Yes |
| גּ | G | Gh (ג) | ❌ No (both G) |
| דּ | D | Dh (ד) | ❌ No (both D) |
| כּ | K | Kh (כ) | ✅ Yes |
| פּ | P | F (פ) | ✅ Yes |
| תּ | T | Th (ת) | ❌ No (both T) |
For TTS purposes, only בכ"פ matter (B/V, K/Kh, P/F).
When does dagesh appear?
Dagesh Lene (light) — hardening, in begedkefet letters:
- At the start of a word (after pause): בַּיִת (bayit)
- After a silent shva: מִסְפָּר (mispar - the פ has dagesh)
Dagesh Forte (strong) — doubling, in any letter except gutturals (אהחע"ר):
- After the definite article הַ: הַבַּיִת (habayit)
- In Pi'el/Pu'al/Hitpa'el verb patterns: סִפֵּר, דִּבֵּר
- After prepositions with article: בַּבַּיִת (babayit)
Common dagesh examples for TTS
Pe/Fe (פּ/פ) — most error-prone:
- פִּיצָה (pizza), פִּייר (Pierre), פַּעַם (pa'am)
- פּוֹלִיטִיקָה (politika), פָּרִיז (Paris)
- אוֹפֶּרָה (opera), קָפּוּצִ'ינוֹ (cappuccino)
Bet/Vet (בּ/ב):
- בְּסֵדֶר (b'seder), בְּדִיוּק (bediyuk), בְּרָכָה (brakha)
- בּוֹסְטוֹן (Boston), בֵּירָה (bira - beer)
Kaf/Khaf (כּ/כ):
- כּוֹס (kos), כַּמָּה (kama), כּוֹכָב (kokhav)
- כְּרִיסְטִינָה (Christina)

⚠️ Common Verb Confusions
| Word | Wrong | Right | Why |
|---|---|---|---|
| סיפר | סָפַר (counted, Pa'al) | סִפֵּר (told, Pi'el) | Different binyan! |
| דיבר | דָּבַר (thing/noun) | דִּבֵּר (spoke, Pi'el) | Noun vs verb |
| ביקש | בָּקַשׁ | בִּקֵּשׁ (asked, Pi'el) | Pi'el, not Pa'al |
| למד | לָמַד (learned, Pa'al) | לִמֵּד (taught, Pi'el) | Pa'al vs Pi'el |
| הסביר | הֶסְבֵּר | הִסְבִּיר (explained, Hif'il) | Hif'il pattern |
| שמר | שָׂמַר (guarded) | שִׂמֵּר (preserved, Pi'el) | Context-dependent |
Rule of thumb:
- Simple action → Pa'al (כָּתַב wrote, שָׁמַר guarded)
- Intensive / caused action → Pi'el (סִפֵּר told, דִּבֵּר spoke, לִמֵּד taught)
- Made someone do → Hif'il (הִסְבִּיר explained, הִזְמִין invited)
- Was done to → Nif'al/Pu'al/Huf'al (נִכְתַּב was written)

| בַּרְצֶלוֹנָה (Barcelona) | dagesh in ב | B not V |
7. Preposition Nikud Rules
Prepositions בְּ (be-), כְּ (ke-), לְ (le-) change nikud in certain situations:

| Shva consonant | Hiriq: בִּ | בִּירוּשָׁלַיִם (birushalayim) |
| Definite article הַ | Absorb article: בַּ | בַּבַּיִת (babayit = in the house) |
| Hataf vowel | Match the hataf | בַּאֲמִתָּה (ba'amita) |
8. Quick Decision Tree
Should I add nikud to this word?
│
├─ Is it a common word with obvious pronunciation?
│ └─ YES → Don't nikud (מה, יש, אני, הוא, שלום, טוב, etc.)
│
├─ Is it a בכ"פ letter that could go either way?
│ └─ YES → Add dagesh if it's P/B/K (not F/V/Kh)
│
├─ Is it a gender suffix (ך, את)?
│ └─ YES → Add nikud for the correct gender
│
├─ Could it be read as a different word (homograph)?
│ └─ YES → Add nikud to disambiguate
│
├─ Is it a foreign name or loanword?
│ └─ YES → Add dagesh for P/B/K sounds
│
├─ Is it a verb where the binyan matters?
│ │
│ ├─ Am I certain of the binyan?
│ │ └─ YES → Add nikud per the binyan table above
│ │
│ └─ Am I NOT certain?
│ └─ DON'T nikud it! Let TTS guess.
│
├─ Am I 100% sure of the correct nikud?
│ ├─ YES → Add it
│ └─ NO → Don't add it!
│
└─ Default: Don't nikud.
9. Common Mistakes to Avoid
- Over-nikuding — Adding nikud to every word makes TTS worse, not better
- Wrong binyan — סָפַר (counted) instead of סִפֵּר (told) is a classic
- Forgetting dagesh in loanwords — פיצה sounds like "fitza" without dagesh
- Kamatz vs Kamatz Katan — Both look like ָ but kamatz katan sounds "o" (כָּל = kol)
- Mixing gender suffixes — ְךָ (male) vs ֵךְ (female) are easy to confuse
- Nikuding when unsure — If you're not 100% certain, DON'T. The TTS model's contextual guess is usually better than wrong nikud.
