The component functions of the high Rise terminal contour in Australian declarative sentences

There is a peculiar sentence intonation pattern, found in English so far as I know only among women, which has the form of a declarative answer to a question, and is used as such, but has the rising inflection typical of a yesno question, as well as being especially hesitant. The effect is as though one were seeking confirmation, though at the same time the speaker may be the only one who has the requisite information. [Lakoff 1975:17.]
