The emergence of commercial wireless devices based on ultra-wideband radio technology (UWB-RT) is widely awaited and anticipated. UWB-RT is not only applicable to communications, imaging and ranging, it also promises to alleviate the problem of increasingly scarce spectrum resources while enabling new wireless applications and business opportunities. These prospects have caught the early attent...

In an RT experiment, subjects were asked to respond with minimal responses to prerecorded dialogs and a manipulated version of these dialogs that contained only intonation and pause information. Response delays and, especially, variances were higher to the impoverished, intonation only, stimuli than to the original recordings. It was also found that intonation only utterances ending in a mid-fr...
