The term "unnatural register" can be referred to as an insincere or pretentious way of speaking or writing. There are a number of synonyms that can be used in place of the term to convey the same meaning. These include affected diction, artificial voice, fake tone, counterfeit speech, feigned language, forced style, contrived manner, and exaggerated inflection. The use of unnatural register can be seen as an attempt to sound more sophisticated or educated, but it often comes across as disingenuous or false. Using more natural language and speaking authentically can help build trust and credibility with the audience.
