Speech perception is the process by which the sounds of language are heard, interpreted and understood. The study of speech perception is closely linked to the fields of phonetics and in linguistics and cognitive psychology and perception in psychology. Research in speech perception seeks to understand how human listeners recognize speech sounds and use this information to understand spoken language. Speech perception research has applications in building computer systems that can recognize speech, in improving speech recognition for hearing- and language-impaired listeners, and in foreign-language teaching.

Famous quotes containing the words speech and/or perception:
“Lying increases the creative faculties, expands the ego, lessens the friction of social contacts.... It is only in lies, wholeheartedly and bravely told, that human nature attains through words and speech the forebearance, the nobility, the romance, the idealism, that—being what it is—it falls so short of in fact and in deed.”
—Clare Boothe Luce (1903–1987)
“The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error.”
—John Stuart Mill (1806–1873)
