Which term describes a speech sound changing due to nearby sounds?

• A. Assimilation
• B. Dialect Formation
• C. Coarticulation
• D. Phoneme Substitution

Answer: (A)

Assimilation happens when a speech sound changes to become more like a nearby sound, making pronunciation easier in continuous speech. This kind of interaction shows up when the articulation of one sound shifts to match the place or voicing of the adjacent sound, so a nasal can take on the same place of articulation as the following consonant (for example, the nasal in a word like input can become a bilabial [m] before a bilabial [p], producing something like [ˈɪmpʊt]). Dialect formation involves regional variation, coarticulation describes the general overlap of articulatory movements across sounds, and phoneme substitution would replace one sound with another rather than reflect a neighbor-influenced change.
