Syllable counts come from vowel tokens; CMUdict does not supply syllable boundaries here. Variant order follows the dictionary and does not rank correctness. This lexicon does not represent every accent or context.

Use chassis in context

Car reviews, computer build guides and engineering videos use chassis often. The CMU entry stresses the first syllable and ends on "see", without a final s. The same spelling serves as the plural in writing, which is a separate pronunciation question this entry does not cover.

REVIEW CHECKLIST

[ ] Listen for vowel sounds, consonants, and word stress in context.
[ ] Check with a speaker or another dictionary when accent or meaning matters.

Practice note: Say "CHA" and "see" as two short beats with no s at the end. In technical audio, pause briefly afterward so the next word does not blur the ending.
