Characteristics of Received Pronunciation (RP)

Received Pronunciation is defined by its clear articulation of vowel and consonant sounds. Compared to other British accents (such as Estuary or Cockney), RP requires more precision and distinct energy at the front of the mouth. Below are the key characteristics that distinguish RP from other accents.

1. Standard Vowel Sounds (Elongation)

While modern RP shares similarities with Southern British English, the long vowel sounds are often more elongated.

  • The Mechanic: Vowels such as /ɑː/ (as in ‘bath’) and /uː/ (as in ‘shoe’) require a sustained airflow.
  • The Contrast: Estuary and Cockney speakers often shorten these sounds and sound more guttural.

2. Stop Consonants

A stop consonant (or plosive) is characterized by a complete closure of the vocal tract followed by a sudden release of air.

  • The Mechanic: In the word ‘hot’, the tongue seals against the alveolar ridge (behind the teeth). When released, there is an audible burst of air. 
  • The Error: Many non-native speakers do not apply the stop (build up the air pressure) prior to the release of the tongue. In RP, the /t/, /p/, and /k/ sounds are crisp and distinct.

3. Rounding of the Lips

One distinctive feature of RP is the active rounding of the lips, particularly for the /w/ sound and vowels like /u/ (goose) or /ɔː/ (thought). The Contrast: If your lips remain flat or relaxed, the sound will lack “resonance”.

4. Non-Rhoticity (The Silent 'R')

  • The Rule: You pronounce the /r/ only if it is immediately followed by a vowel sound (e.g., “Red”, “Bright”).

  • The Exception: If the /r/ is at the end of a word (“Brother”) or before a consonant (“Curve”), it is silent.

  • The Contrast: General American is “Rhotic”, meaning the tongue rolls back to create the /r/ sound in all positions. In RP, the tongue remains flat and relaxed.

5. The Dark /l/

Similar to General American, the RP /l/ at the end of words (“Fall”, “Wall”) is a “Dark /l/.” However, in RP, it is not as heavy.

The Contrast: In Cockney or Estuary English, the /l/ is often replaced entirely by a /w/ sound (pronouncing “Milk” as “Miwk”). In RP, the tongue tip must touch the alveolar ridge.

6. The Dental Fricatives (/θ/ and /ð/)

The /θ/ (Think) and /ð/ (This) sounds require the tongue tip to be placed clearly between the teeth.

  • The Error: Many accents substitute these with /f/, /v/, /d/, or /z/. In RP, there is no compromise; the articulation must be clear.

7. Frontal Resonance (The Oral Setting)

In RP, the “placement” of the voice is at the front of the mouth. This applies not just to the release of consonants, but to the quality of the vowels as well.

  • The Mechanic: The throat (pharynx) must remain relaxed and open. Whether you are releasing a plosive like /t/ or sustaining a vowel like /ɑː/, the sound energy should focus just behind the upper teeth.

  • The Contrast: Cockney and Estuary accents often constrict the pharyngeal muscles, creating a tighter, “guttural” sound deep in the throat. To speak RP, you must visualize the vibration moving away from the throat and into the front of the mouth.

8. Articulation of the /r/ (The Approximant)

When the /r/ sound is pronounced (i.e., before a vowel, as in “Red”), it must be articulated with the tongue, not the lips.

  • The Mechanic: The tip of the tongue raises towards the roof of the mouth but does not curl back as far as in General American (Retroflex).

  • The Contrast: In accents like Cockney or Estuary, the /r/ often deviates to a /w/ sound (Labialization), relying on lip rounding. In RP, the lips remain neutral; the tongue does the work.
