No language has a standard form. Everyone speaks a dialect , a variation of a language spoken by a group of people. Dialects are often regional. Dialects do not indicate the speaker's intelligence. Spoken Language Differs From Written Language.
Spoken language evolves much more quickly than written language.
Spoken language is not inferior to written language. People in print-based cultures tend to be individually focused and linear in thinking. Communication studies focus on both oral and written language. A collection of symbols is a text . A memo, a movie, and a parade are all texts that communicate a message.
