Final answer:
Coarticulation results in allophonic variations and can contribute to dialect variations and phonetically logical misspellings, but increased controversy about phoneme pronunciation is not directly caused by it.
Step-by-step explanation:
As a result of coarticulation, several phenomena occur:
Allophonic variations, where individual phonemes are pronounced differently from how they would be pronounced in isolation, are one such result. This is the subtle change in sound that depends on the surrounding sounds within a word or sentence.
Dialect variations that include nonstandard usage and grammar as well as pronunciation also result from coarticulation. However, they are more strongly influenced by geographical, social, and ethnic factors, rather than just the mechanics of pronunciation.
Misspellings of words that are phonetically logical can sometimes occur as a result of coarticulation, particularly when the spoken form of the word does not match the conventional spelling.
However, increased controversy about how to pronounce specific phonemes is not directly a result of coarticulation; this is more related to dialects and the standardization of language.
