Abstract The phenomenon of acoustic-phonetic variability in the way words, syllables and sound segments are produced in different contexts in fluent continuous speech is well known, and raises the question of whether this variability is[…]
Abstract While on-line handwriting recognition is an area of long-standing and ongoing research, the recent emergence of portable, pen-based computers has focused urgent attention on usable, practical solutions. I will discuss a combination and improvement[…]
Abstract We are interested in providing automated services via natural spoken dialog systems. By natural, we mean that the machine understands and acts upon what people actually say, in contrast to what one would like[…]
Abstract PartI – Decision-tree based quantization of the feature space of a classifierWe describe the design and use of a decision tree to quantize the input feature space of a classifier. The decision tree asks[…]
Abstract A new framework is proposed to integrate the various constraints, both local and global, that are present in the language. Local constraints are captured via n-gram language modeling, while global constraints are taken into[…]
Abstract Probabilistic phonotactics refers to the positional and sequential probabilities of speech sounds within and between spoken syllables and words. I will discuss research examining the role of probabilistic phonotactics in both the perception of[…]
Abstract Explicit expressions for the second order statistics of cepstral components representing clean and noisy signal waveforms are derived. The noise is assumed additive to the signal, and the spectral components of each process are[…]
