Exaggerating the pronunciation of a vowel or consonant?

Question

Is there a word for exaggerating the pronunciation of a vowel or consonant by holding it longer than normal? When conveying this in writing, does it fall in the same category as an accent or dialect (even though it's neither) or are there other rules I should be aware of? Examples: - Heeere's Johnny - lllet's get ready to rumbllle - Halloooooooooooooooooo!

Answer 1

I am not aware of a rhetorical term that describes the way a particular person articulates dialogue. However, if you wished to show what syllable is being emphasized in dialogue so the reader can get a sense of the utterance, it is best to write the emphasized syllable in all caps, so, for example, if someone were to shout, "You are a traitor!", visually displaying how the person is pronouncing it would be, "You are a TRAI-tor!' or "You are a trai-TOR!' To use a stressed accent as one would do with the International Phonetic Alphabet would just make things confusing.
