Key points
- 44 speech sounds; 20 vowels and 24 consonants; 12 monophthongs (5 long, 7 short); 8 diphthongs; 9 voiceless and 15 voiced consonants.
The Sound System of English (RP)
In the English writing system, there are 26 letters of the alphabet, but in spoken Standard English (Received Pronunciation - RP), there are 44 distinct speech sounds (phonemes). This disparity is why English is not a phonetic language; the same letter can represent different sounds, and different letters can represent the same sound.
| Category | Sub-division | Count | Description |
|---|---|---|---|
| Vowel Sounds | Monophthongs (Pure Vowels) | 12 | Single unchanging vowel sounds produced with an unobstructed vocal tract |
| Vowel Sounds | Diphthongs (Vowel Glides) | 8 | A glide from one vowel sound to another within the same syllable |
| Consonant Sounds | Voiced Consonants | 15 | Sounds produced with vibration of the vocal cords |
| Consonant Sounds | Voiceless Consonants | 9 | Sounds produced without vibration of the vocal cords |
| Total Sounds | Vowels (20) + Consonants (24) | 44 | The International Phonetic Alphabet (IPA) standard for RP |
Key Rule
Vowels are produced without any constriction or closure in the vocal tract. The 12 pure vowels (monophthongs) are divided into 5 long vowels (indicated by a length mark /ː/) and 7 short vowels.
Pure Vowels (Monophthongs - 12)
- Short Vowels (7): /ɪ/ (sit), /e/ (bed), /æ/ (cat), /ʌ/ (cup), /ɒ/ (hot), /ʊ/ (put), /ə/ (about - schwa).
- Long Vowels (5): /iː/ (see), /ɑː/ (car), /ɔː/ (saw), /uː/ (too), /ɜː/ (bird).
Diphthongs (Vowel Glides - 8)
- Centring Diphthongs (ending in /ə/): /ɪə/ (ear), /eə/ (air), /ʊə/ (pure/tour).
- Closing Diphthongs (ending in /ɪ/): /eɪ/ (day), /aɪ/ (sky), /ɔɪ/ (boy).
- Closing Diphthongs (ending in /ʊ/): /əʊ/ (go), /aʊ/ (cow).
Exam Tip / Common Error
The Schwa /ə/ is the most frequently occurring vowel sound in unaccented/unstressed syllables in the English language (e.g., the first sound in ago, banana, teacher).
