In this paper we present some experiments that have been performed while developing language models for the PHILIPS Broadcast News system. Three main issues will be discussed: construction of phrases, adaptation of remote corpora to this task, and the combination of the diierent models. Also, per-plexities on the 1997 evaluation data are reported.
BACKGROUND The Amish have not been previously studied for cancer incidence, yet they have the potential to help in the understanding of its environmental and genetic contributions. The purpose of this study was to estimate the incidence of cancer among the largest Amish population. METHODS Adults from randomly selected households were interviewed and a… (More)
The performance of the Philips system for large vocabulary continuous speech recognition has been improved signiicantly by crossword N-phone modelling, enhanced clustering of HMM-states during training, consistent handling of untrained HMM-states during decoding and a new eecient crossword N-phone M-gram decoding strategy. We report word error rate… (More)
In this paper the Philips Broadcast News transcription system is described. The Broadcast News task aims at the recognition of found" speech in radio and television broadcasts without any additional side information e.g. speaking style, background conditions. The system was derived from the Philips continuous mixture density crossword HMM system, using MFCC… (More)
In this paper we describe some characteristics of the acoustic modeling used in the Philips continuous-speech recognition system for the DARPA Hub-4 1997 evaluation, which are related to robustness issues. We aimed at a conceptually simple system: We trained two model sets on 70 hours of the Hub-4 training data, one for within-word and one for crossword… (More)
Last winter my husband and I set out to use Amigam to document a collection of FORTRAN mechanical engineering programs. We had a stack of drawings to include: some generated directly by the FORTRAN programs, and some created using the Aegis Draw 2000 program on the Amiga. It would be a big help to be able to print those drawings with w! I decided to give it… (More)
