‘Uptalk’ is one of the names given to the phenomenon which has recently appeared in English where people use rising intonation at the end of sentences – a pitch pattern that is more usually associated with questions. Some people associate it with American English, others with Australian English – and theories abound as to why it’s emerged at all.
It’s not something I know a huge amount about, but a quick trawl around Google Scholar brings it up in a couple of articles by Paul Foulkes and Gerry Docherty, phoneticians with a sociolinguistic bent at York and Newcastle respectively. I’ll just quote the relevant passages here for information and list the references at the end so that they can be followed up if anyone is sufficiently interested to do so.
One article is titled ‘Phonological variation in the English of England,’ available here in pdf.
“One of the most noticeable innovations in recent years has been the development of rising intonation in the Closed tone category in dialects which traditionally use falls. This has been found in the USA, Australia and New Zealand as well as Great Britain, and has been variously labelled high rising tone (HRT), Australian Question(ing) Intonation (AQI) and uptalk (see Cruttenden 1995, 1997: 129-131, Fletcher, Grabe & Warren in press). The pattern is associated with the upwardly mobile (‘yuppies’) in England (Cruttenden 1997: 130), but lower class and/or female speech elsewhere.
“Because of its perceptual salience, HRT has been the subject of much comment by non-linguists, including the mass media. Some of these comments are highly speculative and empirically untested, for example, that Australian soap operas are responsible for the spread of HRT (Bathurst 1996, Lawson 1998). Others, taking up the mantle of John Walker and others in lamenting change of any kind, identify HRT as a sign of unstoppable decay in modern English (e.g. Bradbury 1996, Norman 2001). Still others draw a logical but naïve conclusion, based on comparison with standard English, that rises indicate questions, and thus the use of rises in declaratives reflects a psychological state of uncertainty. The voice coach Patsy Rodenburg, for example, is quoted by Kennedy (1996) as claiming ‘that rising inflection is about being unsure…you make a question rather than a statement because you are scared’. Such statements are ill-founded in that they equate a particular intonation pattern with a single linguistic function. They thereby fail to take account of issues raised earlier: the form-function problem; the fact that intonational meaning is derived from a complex set of sources; and that social and linguistic evaluation of features may vary from speaker to speaker. It is obvious from examination of intonation patterns in dialects such as Newcastle and Liverpool that rises may be employed in the Closed category without any indication of interrogative meaning or uncertainty. Furthermore, linguists who have analysed HRT have identified its positive discourse functions. It has been shown that HRT serves to track the listener’s comprehension and attention, especially when the speaker is presenting new information. Listeners perceive HRT to be deferential but friendly (Guy & Vonwiller 1984). It also acts as a turn-holding mechanism in narratives (e.g. Warren & Britain 1999).”
The other article is Foulkes and Docherty’s 2006 paper in the Journal of Phonetics (a pre-publication version is available here in pdf); the section I’m quoting is useful mainly for the references to descriptive work in other varieties of English:
“Rising contours in declaratives have begun to emerge recently in English dialects where they are not traditional features, a phenomenon variously referred to as ‘uptalk’ or ‘high rising terminal’ (see Cruttenden, 1995, 1997). This innovation has been observed in the USA (Arvaniti & Garding, 2005), Australia (Guy, Horvath, Vonwiller, Disley, & Rogers, 1986), New Zealand (Britain, 1992; Warren & Britain, 2000), and England (Cruttenden, 1997). In most locations, it is characteristic mainly of young speakers. In the USA, Australia, and New Zealand it is also most common in lower class and/or female speech, but by contrast it seems to be associated with the upwardly mobile in England.”
