'''Intrinsic characteristics''' of [[sound]]s are [[intensity]], [[pitch]], [[duration]] and [[spectral composition]]. Open [[vowel]]s have a higher intrinsic intensity than closed vowels: the intensity of closed vowels is damped by the shape of the vocal tract (Lehiste & Peterson 1959). Open vowels have a longer intrinsic duration as the jaw must be lowered to produce an open vowel (Peterson & Lehiste 1960). The intrinsic pitch of [[consonant]]s is always lower than that of neighbouring vowels because the air needed to produce consonants is obstructed on its way out. Consequently, the pressure in the mouth builds up, resulting in a decreased transglottal pressure difference. This reduction in the transglottal pressure difference causes the vocal folds to vibrate more slowly. Vowels also differ in their intrinsic pitch (Lehiste & Peterson 1961). Vowels can be characterised by their specific spectral composition or [[timbre]].
