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 "back up" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "back up is" sounds like "back up-iz").
In natural sentences, avoid over-stressing "back up" unless it conveys the core contrast or focal point of your message.
