Real-world applications using speech recognition must perform well over a range of dialects. Dier-ences in dialect between the speakers in the training database and the target users often leads to degraded recognition performance. For the BBN Hark Hidden Markov Model (HMM) based system, we have already developed a reasonably eective technique [1] for(More)
A major problem in the spectrographic analysis of children's speech is the poor resolution of formants, which is the result of the widely spaced harmonics of the high fundamental frequency. An attempt has been made to bypass this problem by exciting a child's vocal tract with an artificial larynx, using a fundamental frequency appropriate to a man. This(More)

A gradual reduction in water from snow-melt over the past century has motivated Snowy Hydro Ltd. to pursue a wintertime cloud seeding project in the Snowy Mountains of southeastern Australia. The Snowy Precipitation Enhancement Research Project is one of only a few cloud seeding experiments in the last two decades to employ a randomized design, and the(More)
Development of an improved system for visual classification of cataracts requires a three-step procedure: first, to identify the full range of visible features of cataracts; second, to develop and test scales for the visual assessment of each feature; and third, to establish the epidemiological or clinical validity of each scale for cataract classification.(More)
