In this paper, 1 we propose a novel loss function for the overall risk criterion estimation of hidden Markov models. For continuous speech recognition, the overall risk criterion estimation with the proposed loss function aims to directly maximise word recognition accuracy on the training database. We propose reestimation equations for the HMM parameters,… (More)

24 students, after intake of diazepam or placebo, performed a psychomotor test of finger tapping as a prospective time-estimation task. The task was less overestimated by those who were under the influence of the drug than by the 12 subjects to whom the placebo was given.
30 students, when performing a task that required listening to 19 sentences for 150 sec., overestimated the duration of the task less in the prospective condition than in the retrospective one (46 sec. vs 85 sec.).
