Primary emphasis falls on the first syllable ("KA"). Raise your pitch and sustain the vowel length on this syllable while relaxing the surrounding syllables.
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 followed by a vowel, insert a subtle glide (/w/ or /j/) to connect into the subsequent word without an abrupt glottal stop.
In natural sentences, avoid over-stressing "caffeine" unless it conveys the core contrast or focal point of your message.
