The document discusses the author's understanding of language and speech. The author believes that language is a shared code used to communicate ideas verbally or nonverbally, while speech refers specifically to anything spoken. Language is always communicative, but speech is not always so. For example, a dog barking is just speaking and not using language. The author also notes that language can be expressed verbally through speech or nonverbally through sign language, while speech is always verbal. A speech-language pathologist helps patients with both their speech and language abilities, as both are needed for proper communication.
