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