About the IPA
The International Phonetic Alphabet (IPA) is a standardized system of phonetic notation created by the International Phonetic Association in 1888. Unlike spelling systems that vary between languages, the IPA provides a consistent way to represent the sounds of spoken language regardless of orthography.
The current IPA chart (2020 revision) contains 107 consonant and vowel symbols, plus numerous diacritics and suprasegmentals for precise phonetic transcription. It's used by linguists, speech-language pathologists, lexicographers, language teachers, singers, actors, and constructed language creators.
Consonants (Pulmonic)
The vast majority of consonants across world languages are pulmonic egressive — produced by pushing air from the lungs. The IPA organizes them by place of articulation (where in the mouth) and manner of articulation (how airflow is obstructed).
| Manner ↓ / Place → | Bilabial | Labiodental | Dental | Alveolar | Postalveolar | Palatal | Velar | Glottal |
|---|---|---|---|---|---|---|---|---|
| Plosive | p b | t d | k g | ʔ | ||||
| Nasal | m | ɱ | n | ɲ | ŋ | |||
| Trill | ʙ | r | ||||||
| Tap/Flap | ⱱ | ɾ | ||||||
| Fricative | ϕ β | f v | θ ð | s z | ʃ ʒ | x ɣ | h ɦ | |
| Lateral fricative | ɬ ɮ | |||||||
| Approximant | ʋ | ɹ | j | ɰ | ||||
| Lateral approximant | l | ʎ | ʟ |
Note: Where symbols appear in pairs, the one on the right represents a voiced consonant (vocal cords vibrating). This chart shows key examples; the full IPA chart includes retroflex, pharyngeal, and uvular places of articulation.
Other Consonants
Non-Pulmonic Consonants
| Type | Symbols | Examples |
|---|---|---|
| Clicks | ʘ ǀ ǃ ǂ ǁ | Found in Khoisan languages, Zulu, Xhosa |
| Voiced implosives | ɓ ɗ ʄ ɠ ʛ | Sindhi, Swahili, Vietnamese |
| Ejectives | pʼ tʼ kʼ sʼ | Georgian, Amharic, Quechua |
Co-articulated Consonants
- ʍ — Voiceless labial-velar approximant (English "which" in some dialects)
- w — Voiced labial-velar approximant (English "water")
- ɥ — Voiced labial-palatal approximant (French "huit")
- ɕ ʑ — Voiceless/voiced alveolo-palatal fricatives (Mandarin, Polish)
Vowels
The IPA vowel chart plots vowels by tongue position: height (close/open, vertical axis) and backness (front/back, horizontal axis), plus lip rounding.
| Height ↓ / Position → | Front Unrounded | Front Rounded | Central | Back Unrounded | Back Rounded |
|---|---|---|---|---|---|
| Close | i | y | ɨ ʉ | ɯ | u |
| Near-close | ɪ | ʏ | ʊ | ||
| Close-mid | e | ø | ɘ ɵ | ɤ | o |
| Mid | ə | ||||
| Open-mid | ɛ | œ | ɜ ɞ | ʌ | ɔ |
| Near-open | æ | ɐ | |||
| Open | a | ɶ | ɑ | ɒ |

Diacritics
Diacritics modify base symbols to indicate fine phonetic details:
| Diacritic | Example | Meaning |
|---|---|---|
| ◌̥ | n̥ | Voiceless |
| ◌̬ | s̬ | Voiced |
| ◌ʰ | tʰ | Aspirated |
| ◌̃ | ã | Nasalized |
| ◌ː | aː | Long (lengthened) |
| ◌ˑ | aˑ | Half-long |
| ◌̆ | ă | Extra-short |
| ◌̚ | p̚ | No audible release |
| ◌ʷ | kʷ | Labialized |
| ◌ʲ | tʲ | Palatalized |
| ◌ˠ | tˠ | Velarized |
| ◌ˤ | tˤ | Pharyngealized |
| ◌̺ | t̺ | Apical |
| ◌̻ | t̻ | Laminal |
| ◌̹ | ɔ̹ | More rounded |
| ◌̜ | ɔ̜ | Less rounded |
Suprasegmentals
Suprasegmentals indicate features that extend over multiple segments:
Stress and Length
- ˈ — Primary stress (before stressed syllable): /ˈwɔtər/ "water"
- ˌ — Secondary stress: /ˌɪntərˈnæʃənəl/ "international"
- ː — Long: /biːt/ "beat" vs. /bɪt/ "bit"
- ˑ — Half-long
Tone Markers (for Tone Languages)
- ˥ or ◌́ — Extra high / High tone
- ˦ — High
- ˧ or ◌̄ — Mid
- ˨ — Low
- ˩ or ◌̀ — Extra low / Low tone
- ◌̌ — Rising
- ◌̂ — Falling
Intonation
- | — Minor (foot) group
- ‖ — Major (intonation) group
- ↗ — Global rise
- ↘ — Global fall
Phonetic vs. Phonemic Transcription
Phonetic Transcription [brackets]
Records actual pronunciation with fine phonetic detail:
English "butter": [ˈbʌɾɚ] (American) or [ˈbʌtʰə] (British)
Shows flapped /t/ in American English, aspirated /t/ in British
Phonemic Transcription /slashes/
Records only contrastive sounds (phonemes) in a language:
English "butter": /ˈbʌtər/
Ignores predictable phonetic details, shows underlying form
