Common Pronunciation Traps & Learner Mistakes
The Trap: Avoid pronouncing every vowel with full acoustic weight. Non-native speakers often over-enunciate unstressed vowels.
How Native Speakers Say It: Only give full vowel clarity to the primary stressed syllable. Relax all unstressed vowels into a neutral, low-energy schwa (⁄ə⁄).
Connected Speech & Natural Conversational Flow
When "coenzymes" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "coenzymes is" sounds like "coenzymes-iz").
Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "coenzymes" aligns naturally with adjacent words.
