Pronunciation: /ˌrɛp·lɪˈkeɪ.ʃən/ (US: /ˌrɛp.lɪˈkeɪ.ʃən/, UK: /ˌrɛp.lɪˈkeɪ.ʃən/, AU: /ˌrɛp.lɪˈkeɪ·ʃən/). Primary stress on the third syllable ‘ca’ in -ca-tion, secondary stress on the first syllable. Lips relax, tip of tongue just behind lower teeth for r, mid tongue height for ɛ, and the long aɪ sound becomes eɪ as in “case.” End with schwa-ish ɘn. You’ll hear a clear ja‑shun in careful speech. Practice with slow syllables: rep-li-ca-tion → re-PLI-CA-tion, then full speed.”keywords:[

Common issues: 1) Misplacing the stress, saying it RE-pli-CATION; 2) Flattening the /eɪ/ to a short /e/ in -ca-tion; 3) Slurring the /l/ into the /p/ sequence. Corrections: (1) keep primary stress on the -ca- syllable: re-PLI-ca-tion; (2) pronounce the /eɪ/ as a long vowel in -ca-tion: /keɪ/; (3) enunciate /p/ and /l/ as distinct consonants in sequence: /pl/ cluster with a light release. Practice by isolating the cluster: /pl/ with a brief pause between /l/ and /ɪ/ to avoid gobbling. Also ensure the final /ən/ ends with a light n.

Across US/UK/AU, the core is similar, but small shifts exist: US tends toward a slightly flatter /ɪ/ in the second vowel and a reduced final /ən/; UK often preserves a slightly higher /iː/ or /ɪ/ quality in the middle syllable and keeps a crisper /t/ release before /ɪən/?; AU resembles UK usually but with broader vowel qualities and oftenə less rhoticity in non-initial positions. The main differences: rhoticity (US rhotic /ɹ/ in all positions, UK often non-rhotic in certain accents but with linking r in some dialects) and vowel quality in /eɪ/ and /ɪ/ leading to subtle shifts in -ca-tion.”,

The difficulty comes from the multi-syllabic structure and consonant cluster /pl/ followed by a stressed /keɪ/ and final /ʃən/; this requires smooth gestural coordination across a sequence of stops, liquids, and a diphthong. The /pl/ cluster can be tricky to articulate without inserting a vowel; the /eɪ/ is a tense, long vowel; and the final /ən/ can be devoiced or reduced in rapid speech. Practicing with slow, precise mouth movements helps stabilize rhythm and stress.

A unique challenge is keeping the stress on the -ca- or the penultimate syllable depending on pronouncing style, while maintaining a clear /eɪ/ in the middle and a soft final /ən/. Additionally, the /pl/ cluster requires the tongue to move quickly from a bilabial stop to a lateral /l/ while maintaining voicing and a stable jaw position. You’ll benefit from slow, deliberate practice focusing on the sequence: re-PLI-ca-tion, then gradually accelerate.
