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