What is speech?
Speech is the vocal form of language used by humans. According to the syntactic rules that control how lexical words work in sentences, each language utilizes phonetic combinations of vowel and consonant sounds to create the sound of its words.
Those words are then used in their semantic nature as words in that language's lexicon.
Speaking involves many distinct purposeful speech actions, such as informing, asserting, inquiring, persuading, and guiding, and speakers can transmit meaning through their vocalizations by using enunciation, intonation, volume, pace, and other non-representational or paralinguistic features.
Speakers unwittingly convey a variety of social cues in their speech, including sex, age, place of origin (by accent), bodily states (vigor and weakness, alertness and drowsiness, health or disease), and psychological states.
