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.
Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "polyhedra" aligns naturally with adjacent words.
