American English

New SoundDifficulty: 4/5

This is the rarest French nasal vowel and many French speakers themselves merge it with the 'in' nasal /ɛ̃/. Start from the French 'eu' sound (open version, as in 'peur'). Now nasalise it — let air flow through your nose while holding that rounded, front-of-centre vowel. No 'n' at the end. Your 'under' vowel is a rough starting neighbourhood — nasalise it and add lip rounding.

Bridge from: under, fun (ʌn (as in 'under'))

Common mistakes:

  • Merging it with the 'in/vin' nasal (acceptable in casual French but good to know the distinction)
  • Pronouncing the final 'n'
  • Not rounding the lips

Drill sequence:

  1. under → nasalise → round lips → un
  2. fun → nasalise → round → brun
  3. peur → nasalise → /œ̃/

British English

New SoundDifficulty: 4/5

Start from the French open 'eu' (as in 'peur') — your 'bird' vowel with lip rounding. Now add nasalisation: let air flow through your nose while holding the vowel. The result is the French nasal 'un'. This is arguably the hardest French vowel, but the good news is that most French speakers merge it with /ɛ̃/ anyway.

Bridge from: under (ʌn)

Common mistakes:

  • Not nasalising enough
  • Not rounding enough
  • Adding a final 'n' consonant

Drill sequence:

  1. bird → round → peur → nasalise → un

Australian / NZ English

New SoundDifficulty: 3/5

Since your 'bird' vowel already bridges to French 'eu', the nasal version is one step further. Take that rounded central vowel and add nasal airflow — hum while holding it. Drop any final 'n' consonant. Many native French speakers merge this with /ɛ̃/ (the 'in' nasal), so even an approximation is acceptable.

Bridge from: under, fun (ɐn)

Common mistakes:

  • Pronouncing the 'n'
  • Not enough rounding

Drill sequence:

  1. bird vowel → nasalise → round → un
  2. fun → nasalise → round → brun

Irish English

New SoundDifficulty: 4/5

Build from the French open 'eu' sound with added nasalisation. This is the most complex French vowel — rounded, front-of-centre, and nasal all at once. Since even native French speakers are merging it with /ɛ̃/, a reasonable approximation is perfectly acceptable.

Bridge from: under (ʊn / ʌn)

Common mistakes:

  • Merging with English 'un' sound
  • No lip rounding

Drill sequence:

  1. under → round lips → nasalise → un

Scottish English

New SoundDifficulty: 3/5

Your advantage on French 'eu' (from the fronted Scottish vowel system) extends here. Take the rounded central vowel and add nasal airflow. Since this sound is merging with /ɛ̃/ in modern French, even a close approximation serves you well.

Bridge from: under (ʌn)

Common mistakes:

  • Not rounding
  • Pronouncing final 'n'

Drill sequence:

  1. Scottish 'bird' → round → nasalise → un

Indian English

New SoundDifficulty: 3/5

Combine two skills: lip rounding for French eu (which you need to learn) with nasalisation you already have from Hindi. If you can produce French eu, just add Hindi-style nasalisation. Since this vowel is merging with /ɛ̃/ in modern French, even an approximation works.

Bridge from: under + Hindi nasality (ʌn + nasalisation)

Common mistakes:

  • Base vowel quality wrong
  • Nasalisation technique is fine — vowel is the challenge

Drill sequence:

  1. Learn French eu → add Hindi nasalisation → un
  2. peur → add anusvara-style buzz → /œ̃/

South African English

New SoundDifficulty: 3/5

Your NURSE vowel bridges to French eu — add nasalisation. This is merging with /ɛ̃/ in modern French, so approximation is acceptable.

Bridge from: under, nurse (ɜːn)

Common mistakes:

  • Pronouncing the n
  • Not enough rounding

Drill sequence:

  1. nurse → round → nasalise → un

Nigerian / W. African English

Small AdjustmentDifficulty: 3/5

You have the nasalisation skill from Yoruba/Igbo. The challenge is the base vowel quality — French /œ̃/ needs a rounded front-of-centre vowel with nasalisation on top. First work on the eu vowel, then add your natural nasalisation.

Bridge from: Native nasal vowels + eu quality (ɔ̃ / nasalised vowel)

Common mistakes:

  • Using wrong base vowel
  • Substituting a back nasal vowel

Drill sequence:

  1. Learn eu vowel → add Yoruba/Igbo nasalisation → un
