Here's why:
* The Speech Chain: The speech chain is a model that describes the stages of speech production and perception. It starts with the speaker's intention and ends with the listener's comprehension.
* Linguistic Level: This level refers to the actual message being conveyed - the thoughts, ideas, and language that the speaker wants to communicate.
* Brain's Role: The brain is responsible for:
* Generating ideas: The speaker's intention originates in the brain.
* Formulating language: The brain chooses words, constructs grammatical structures, and organizes the message.
* Decoding language: The listener's brain receives auditory signals, interprets the sounds, and understands the intended message.
While other levels of the speech chain involve physical processes like the vocal tract and auditory system, the linguistic level is purely cognitive and takes place within the brain.
