Final answer:
The term describing the repetition of final consonant sounds in stressed syllables with different vowels is consonance. Consonance, which contributes to the rhythm and musicality of poetry, differs from assonance that repeats vowel sounds within words.
Step-by-step explanation:
The term used to describe the repetition of final consonant sounds in stressed syllables containing dissimilar vowel sounds is consonance.
