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 "bdf" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "bdf is" sounds like "bdf-iz").
Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "bdf" aligns naturally with adjacent words.
