Speech sound refers to the various audible components that make up speech in human language. It is the smallest unit of sound within language that carries meaning and is produced by the movement and coordination of different articulatory organs, such as the lips, tongue, teeth, and vocal cords. Speech sounds are the building blocks of spoken language and are classified into different categories based on their production, perception, and acoustic features.
There are two main types of speech sounds: consonants and vowels. Consonants are produced by the partial or complete obstruction of airflow, while vowels are produced with an open vocal tract, allowing the free flow of air. Each speech sound is characterized by its distinctive features, including place and manner of articulation, voicing, and duration.
Speech sounds are organized and combined to form words, which in turn form sentences and convey meaning. They are essential for effective communication and serve as the basis for language acquisition and development. Children learn to produce speech sounds by imitating and practicing the sounds they hear around them, while adults rely on the mastery of speech sounds to understand and generate language.
In the field of linguistics, the study of speech sounds is known as phonetics. It examines the physical properties and acoustic characteristics of speech sounds, as well as their production and perception. Phonetics helps to identify and analyze the sounds and patterns that exist in different languages, contributing to our understanding of the diversity and universality of human language.
The word "speech" is derived from the Middle English word "speche", which itself stems from the Old English word "spǣċ" meaning "discourse" or "talk". The etymology of "spǣċ" can be traced back to the Proto-Germanic word "*spekōną".
The word "sound" originates from the Old English word "sund", which meant "noise", "sound", or "the sensation produced through the ear". It can also be traced back to the Proto-Germanic word "*swunduz", meaning "a sound" or "a noise".
Therefore, when these two words are combined, "speech sound" refers to the sounds produced during speech or the sounds used to communicate through spoken language.
