Results are presented on the DARPA Resource Management (RM) task for both speaker-dependent (SD) and speaker-independent (SI) parts. Using triphone models based on LDA and continuous mixture densities, significant improvements have been observed and the following word error rates have been achieved: for the SD part, 7.8% without grammar and 1.5% with word pair; and for the SI part, 17.2% and 4.6%, respectively. These scores are averaged over 1200 SD or SI evaluation sentences and are among the best published so far on the RM database.}}, author = {{Aubert, Xavier L. and Haeb-Umbach, Reinhold and Ney, Hermann}}, booktitle = {{ICASSP, Minneapolis}}, title = {{{Continuous Mixture Densities and Linear Discriminant Analysis for Improved Context-Dependent Acoustic Models}}}, year = {{1993}}, } @article{11749, abstract = {{To decrease the hazards of using mobile phones while driving, voice processing provides several tools that simplify their use: echo cancellation allows comfortable hands-free conversation, feedback and user guidance by voice allow to operate the phone in eyes-busy situations, and last not least speech recognition frees from keypad data entry to operate the telephone. A comprehensive view of a device incorporating the above mentioned technologies, which has been realized as an add-on for the Philips car telephone family, will be presented. Emphasis is placed on the speech recognition algorithms. Robustness of the algorithms to changing acoustic environment was improved by estimating and subtracting the long-term spectrum. We will show that, if this operation is done recursively, it is equivalent to the high-pass filtering or RASTA (Relative Spectral Approaches) methods recently proposed in the literature.}}, author = {{Dobler, Stefan and Geller, Dieter and Haeb-Umbach, Reinhold and Meyer, Peter and Ney, Hermann and Ruehl, Hans Wilhelm}}, journal = {{Speech Communication}}, title = {{{Design and use of speech recognition algorithms for a mobile radio telephone}}}, year = {{1993}}, } @inproceedings{11788, abstract = {{Four methods were used to reduce the error rate of a continuous-density hidden Markov-model-based speech recognizer on the TI/NIST connected-digits recognition task. Energy thresholding sets a lower limit on the energy in each frequency channel to suppress spurious distortion accumulation caused by random noise. This led to an improvement in error rate by 15%. Spectrum normalization was used to compensate for across-speaker variations, resulting in an additional improvement by 20%. The acoustic resolution was increased up to 32 component densities per mixture. Each doubling of the number of component densities yielded a reduction in error rate by roughly 20%. Linear discriminant analysis was used for improved feature selection. A single class-independent transformation matrix was applied to a large input vector consisting of several adjacent frames, resulting in an improvement by 20% for high acoustic resolution.

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.}}, author = {{Steinbiss, Volker and Ney, Hermann and Haeb-Umbach, Reinhold and Train, B.-H. and Essen, U. and Kneser, Reinhard and Oerder, Martin and Meier, H.
