In this paper, we describe a novel two-pass search strategy for large vocabulary continuous speech recognition. The first-pass of this strategy uses a regular time-synchronous beam search with rough models to generate a word lattice. Then, the second-pass search derives exact results from the word lattice using more accurate models. This search is(More)
A 51-year-old woman suffering from dyspnoea and refractory bilateral pleural effusions is discussed. The effusion was characterized as a transudate and cardiac decompensation and renal insufficiency were initially suspected. Diuretic agents were not effective and the patient required bilateral chest water-sealed drainage tubes for 4 months, after exclusion(More)
This paper presents an improved phonemehistory-dependent (PHD) search algorithm. This method is an optimum algorithm under the assumption that the starting time of a recognized word depends on only a few preceding phonemes (phoneme history). The computational cost and the number of recognition errors can be reduced if the phoneme-historydependent search(More)
In vivo antiarrhythmic effects of diltiazem hydrochloride and nifekalant hydrochloride, a pure class III antiarrhythmic drug (Vaughan Williams' classification), on adrenaline induced ventricular arrhythmias were examined in halothane anesthetized guinea pigs. Continuous adrenaline infusion (12.5 microg/kg per min) induced ventricular arrhythmias.(More)
This paper describes a practical dictation system that is able to compensate for the lack of a large text database and reports on the results of eld tests in which the system was used to make medical rehabilitation diagnosis reports in a hospital. Our dictation system uses two recognition engines: continuous speech recognition and isolated word (including(More)
