There are many different types of communication systems around the world. The communication systems that I will focus on are human, linguistic and nonverbal. Language is unique to humans and therefore evolves with humans. There are several anatomical regions that are involved in speech such as the respiratory system, phonatory system and the articulatory system. We communicate not just through speech but nonverbally as well. We observe several types of nonverbal communication such as body language, visual, tactical, gestures, facial expressions, and many more. The study of languages is known as linguistics. However, linguistics is more than the study of languages. It includes phonetics, phonology, morphology, semantics, and syntax. Phonetics is the study of speech sounds and physiological production and acoustic qualities. Humans across the world recognize approximately 40 different speech sounds that are common in all languages. Languages are made up of vowels and consonants, and when they are put together they form syllables to carry the sounds. The process of how our brains organize the vowel and consonant speech sounds is coarticulation. In working with speech disorders, the key elements are repetition and the speed of articulation. The individual must be aware of articulators. An articulator is, for example, the tongue movement and placement. A human can speak up to 200/300 words per minute and understand up to 500 words per minute. Humans use many forms of nonverbal communication such as body language, gestures, facial expressions and our senses. We use nonverbal communication because it is quick and efficient. In the speech chain, one must have a sender and receiver in order to communicate. A human can recognize body language as a form of communication by the sense of personal space such as sitting or standing too close. We identify whether the receiver is listening to the sende
