The Harvard Sentences are a collection of sample phrases that are used for standardized testing of Voice over IP, cellular, and other telephone systems. They are phonetically-balanced sentences that use specific phonemes at the same frequency they appear in English.
IEEE Recommended Practices for Speech Quality Measurements sets out 72 lists of 10 phrases, described as the "1965 Revised List of Phonetically Balanced Sentences (Harvard Sentences)." They are widely used in research in telecoms, speech and acoustics, where standardized and repeatable sequences of speech are needed. The Open Speech Repository provides some freely usable, prerecorded WAV files of Harvard Sentences in American and British English, in male and female voices.

Famous quotes containing the words harvard and/or sentences:
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
“The aphorism, the apothegm, in which I am the first among the Germans to be a master, are the forms of “eternity”; it is my ambition to say in ten sentences what everyone else says in a book—what everyone else does not say in a book.”
—Friedrich Nietzsche (1844–1900)
