Human speech is the method by which people communicate using sounds produced by the vocal cords. It involves the coordination of various body parts, including the lungs, vocal cords, tongue, and lips, to create distinct sounds and words. This ability allows individuals to express thoughts, emotions, and ideas effectively. The study of human speech falls under the field of linguistics, which examines how languages are structured and used. Speech can vary widely across different cultures and regions, leading to diverse languages and dialects. Additionally, phonetics focuses on the sounds of speech, while phonology explores how these sounds function within particular languages.
