Received Pronunciation (RP)
The mechanics of non-rhoticity, trap-bath splits, and traditional British authority.
The Architecture of RP
Received Pronunciation (RP) is the traditionally prestigious accent of Standard English in the UK. Modern RP (often called SSBE - Standard Southern British English) has evolved, but the core structural markers remain distinct from North American varieties.
Core Acoustic Markers
| Feature | Description | Acoustic Target |
|---|---|---|
| Non-Rhoticity | /r/ is only pronounced before a vowel. Post-vocalic /r/ becomes a schwa or lengthens the preceding vowel. | Absence of F3 lowering at syllable codas. |
| Trap-Bath Split | Lengthening and backing of the vowel in words like 'bath', 'grass', 'dance' to /ɑː/. | F1 ~700Hz, F2 ~1050Hz (Back, unrounded). |
| T-Glottalization | Allophonic variation of /t/ to a glottal stop [ʔ] in certain coda positions (though traditional RP avoids this intervocalically). | Abrupt cessation of acoustic energy. |
| Intonation Contour | Wider pitch range and more dramatic declination over utterances compared to GenAm. | Higher F0 peaks on stressed syllables. |
Common Acquisition Mistakes
- Over-glottalization: Adopting Estuary English features (like intervocalic glottal stops in 'water') while attempting traditional RP.
- Intrusive 'R' failure: Failing to link adjacent vowels across word boundaries (e.g., 'law(r) and order').
