Speech Speech Speech is human vocal communication using language. Each language uses phonetic combinations of a limited set of perfectly articulated and individualized vowel and consonant sounds that form the sound of its words (that is, all English words sound different from all French words, even if they are the same word, e.g., "role" or "hotel"), and using those words in their semantic character as words in the lexicon of a language according to the syntactic constraints that govern lexical words' function in a sentence. In speaking, speakers perform many different intentional speech acts, e.g., informing, declaring, asking, persuading, directing, and
Closure with a twist formula_40 and a formula_44 such that formula_45 where formula_46 and formula_47 for all formula_48. Closure with a twist Closure with a twist is a property of subsets of an algebraic structure. A subset formula_1 of an algebraic structure formula_2 is said to exhibit closure with a twist if for every two elements there exists an automorphism formula_4 of formula_2 and an element formula_6 such that where "formula_8" is notation for an operation on formula_2 preserved by formula_4. Two examples of algebraic structures which exhibit closure with a twist are the cwatset and the generalized cwatset, or GC-set. In mathematics, a
