The Trap: Single-syllable words like "x15" carry primary acoustic prominence in isolation, but can be swallowed in rapid connected speech.

🔗 Consonant-Vowel Linking (Liaison)

When "x15" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "x15 is" sounds like "x15-iz").
