Philipsen’s Speech Code Theory says that each and every culture has their own speech codes. Speech Codes are systems of socially constructed symbols and meanings, premises, and rules that pertain to interaction between those who make up the particular culture. These speech codes used by speakers and listeners are utilized to create and interpret their communication which make up their realities.

If one were to view the culture and communication of the Lumbee Indians of south-eastern North Carolina they’d easily be able to see support for the Speech Codes Theory. This tribe has developed its own particular speech codes that flood their communication. Their speech codes are woven into their communication and become more prevalent when you view the interaction between those who share the culture.
