Speech

Human vocal communication using language is Speech. Languages use phonetic combinations of vowel and consonant sounds.

Although people ordinarily use speech in dealing with other persons,  when people swear they do not always mean to communicate anything to anyone, and sometimes in expressing urgent emotions or desires they use speech as a quasi-magical cause, as when they encourage a player in a game to do or warn them not to do something. There are also situations in which people engage in solitary speech. People talk to themselves sometimes in acts that are a development of what some psychologists have maintained is the use of thinking of silent speech in an interior monologue to vivify and organize cognition, sometimes in the momentary adoption of a dual persona as self-addressing self as though addressing another person. Solo speech can be used to memorize.

The speech is compared with written language, which may differ in its vocabulary, syntax, and phonetics from the spoken language, a situation called diglossia. Speech is the subject of study for linguistics, cognitive science, communication studies, psychology, computer science, speech pathology, otolaryngology, and acoustics. Researchers study many different aspects of speech: speech production and speech, perception of the sounds used in a language, speech repetition, speech errors, and the ability to map heard spoken words onto the vocalizations needed to recreate them, which plays a key role in children’s enlargement of their vocabulary, and what different areas of the human brain, such as Broca’s area and Wernicke’s area, underlie speech.  The speech is compared with written language, which may differ in its vocabulary, syntax, and phonetics from the spoken language, a situation called diglossia.
