COMPUTER SPEECH AND LANGUAGE SPECIAL ISSUE ON NEW COMPUTATIONAL PARADIGMS FOR ACOUSTIC MODELLING IN SPEECH RECOGNITION AIM In recent years there has been an upsurge in interest in approaches to speech pattern processing which go beyond the conventional HMM framework, motivated by limitations of current systems both in performance and in that current modeling assumptions are not consistent with observations about the speech process. Researchers observe that current models are fragile in noise, limited in their ability to handle pronunciation variation, and costly for large vocabulary spontaneous speech transcription. They also point to limitations of HMMs in representing non-stationary behaviour of speech and temporal properties. The aim of this issue is to bring together up-to-date reviews of new computational techniques, including those that are being explored in other fields, with original work on extending and evaluating these techniques on speech recognition tasks. Papers are therefore solicited in the area of computational paradigms for acoustic modeling in speech recognition. Topics of interest include (but are not limited to): * Extensions and developments of HMMs, such as multi-stream models, factorial HMMs and graphical models in general * Computational models motivated by the need to accommodate structure in speech patterns which is potentially relevant for recognition but which is absent from the conventional HMM formalism (e.g. trajectories, linguistic features). * Computational models which accommodate novel feature extraction techniques that go beyond the traditional fixed frame-rate analyses. * Non-HMM-based approaches, or hybrid systems combining other classifiers with HMMs * Theoretical developments (of HMMs and extensions) which appear to have significant implications for speech processing. Manuscript submission Authors should send copies of their papers to guest editor Professor Martin Russell, by 31 March 2001. Authors should follow the CSL guidelines for paper submission; electronic submissions are encouraged preferably in postscript.
