  abstract     = {{This paper gives a status report of the Philips research system for phoneme-based, large-vocabulary, continuous-speech recognition. Like for many other systems, the recognition architecture is based on an integrated statistical approach. We describe the characteristic features of the system as opposed to other systems: 1. The Viterbi criterion is consistently applied both in training and testing. 2. Continuous mixture densities are used without tying or smoothing. 3. Time-synchronous beam search in connection with a phoneme look-ahead is applied to a tree-organized lexicon. The system has been successfully applied to the American English DARPA RM task. Here, we report experimental results for a German 13 000-word Philips internal dictation task. In addition to the scientific prototype, a PC version has been set up which is described here for the first time.}},

  abstract     = {{The interaction of linear discriminant analysis (LDA) and a modeling approach using continuous Laplacian mixture density HMM is studied experimentally. The largest improvements in speech recognition could be obtained when the classes for the LDA transform were defined to be sub-phone units. On a 12000 word German recognition task with small overlap between training and test vocabulary a reduction in error rate by one-fifth was achieved compared to the case without LDA. On the development set of the DARPA RM1 task the error rate was reduced by one-third. For the DARPA speaker-dependent no-grammar case, the error rate averaged over 12 speakers was 9.9%. This was achieved with a recognizer using LDA and a set of only 47 Viterbi-trained context-independent phonemes.}},

  abstract     = {{This paper describes the improvements in a time synchronous beam search strategy for a 10000-word continuous speech recognition task. The improvements are based on two measures: a tree-organization of the pronunciation lexicon and a novel look-ahead technique at the phoneme level, both of which interact directly with the detailed search at the state levels of the phoneme models. Experimental tests were performed for four speakers on a 12306-word task. As a result of the above measures, the overall search effort was reduced by a factor of 17 without a loss in recognition accuracy.}},

  abstract     = {{In a large vocabulary continuous speech recognition task the search for the "best" (in the maximum-a-posteriori sense) word sequence is the most (computing) time consuming part of the system. End-of-word hypotheses are created almost every time frame. With a stochastic language model every lexicon entry is an admissible successor candidate. By using a "fast match" module which scores the word candidates according to their acoustic feasibility ahead of the current time frame, the search cost can be considerably reduced. Only the fraction of the words with favourable fast match scores will be further processed in the detailed match, where the likelihood of a segment of acoustics given the word model is computed. We derive a novel word selection strategy which is "consistent" in the sense that it introduces no additional decoding errors and which still reduces the search space by a factor of 2 - 3 compared to standard Viterbi beam search. Giving up the consistency requirement, pruning strategies can be deduced which further reduce the search effort significantly: the size of the word startup list is reduced to 2% - 4% of its original size with a modest increase in error rate by l%-2%.}},

  abstract     = {{The resonant bias coil technique requires even-numbered transitions to be written on even-numbered clock cycles, and odd-numbered transitions on odd-numbered clock cycles. This constraint is met by double-spaced run-length-limited (d, k, 2) codes where the number of consecutive zeros is even. Exploiting the polarity of the transitions, a detection window that has double the size of the code bit period is possible. The authors describe a detection circuit that achieves the enlarged detection window, and present a phase detector which is particularly simple to implement. Channel bit-error-rate measurements have been carried out employing a rate 1/3 (2, 8, 2) code. Error rates of 10/sup -8/ were achieved for recording densities up to 33 kb/in. The results demonstrate the expected excellent immunity of the direct overwrite scheme to bloom.}},

  abstract     = {{The common basis of coherent and differentially coherent detection is considered from the viewpoint of carrier recovery as the estimation of fading distortion. In the differentially coherent receiver a simple estimate of the fading distortion is used whereas the coherent receiver uses the optimal estimate. The bit error rates (BERs) for M-ary PSK (phase-shift keyed) and DPSK (double phase-shift keyed) transmission are calculated using a single method of calculation for both detection schemes. The calculation takes into account nonperfect carrier recovery, cochannel interference, and diversity. The results allow a direct comparison of the two schemes and show that coherent detection is preferable in many realistic fading environments.}},
