1. Abstract

In this talk I briefly survey some of my previous research and then even more briefly extrapolate as to future extensions of this work.

I will talk about improving Automatic Speech Recognition (ASR) for speakers with speech disabilities by incorporating knowledge of their speech production. This involves the acquisition of the TORGO database of disabled articulation which demonstrates several consistent behaviours among speakers, including predictable pronunciation errors. Articulatory data are then used to train augmented ASR systems that model the statistical relationships between the vocal tract and its acoustic effluence. I show that dynamic Bayesian networks augmented with instantaneous articulatory variables outperform even discriminative alternatives. This leads to work that incorporates a more rigid theory of speech production, i.e., task-dynamics, that models the high-level and long-term aspects of speech production. For this task, I devised an algorithm for estimating articulatory positions given only acoustics that significantly outperforms the former state-of-the-art.

Finally, I present ongoing work into the transformation of disabled speech signals in order to make them more intelligible to human listener and I conclude with some thoughts as to possible paths we may now take.

Text Summarization Workshop at Canadian AI (TS11)

Automatic text summarization (TS) has been a matter of active research for over a decade now. Doing TS really well would require insights from statistics, machine learning, linguistics and cognitive science, to name a few. Despite a great deal of research effort, state-of-the-art TS systems achieve summary quality much lower than even untrained human summarizers. There is room for improvement and much interesting work to do.
