Abstract:
Much has been achieved in the Second Millennium in the development
of cochlear implants for profoundly deaf people, but further advances
in the Third Millennium should result in most severely to profoundly
deaf people being able to communicate effectively in a hearing community.

Abstract:
This paper describes two related systems which provide frameworks for
encoding linguistic knowledge into formal rules within the context
of a trainable probabilistic model. The first system, TINA, drives
top-down from sentence level structure, terminating in either words
or syllables. It's main purpose is to provide a meaning representation
for the sentence. The other system, ANGIE, operates bottom-up from
phonetic or orthographic units, characterizing word substructure.
It provides a framework for both phonological rule modelling and letter-to-sound/sound-to-letter
transformations. The two systems logically converge on the syllable
or word layer. We have recently been successful in integrating their
combined constraint into a recognizer search, achieving considerable
improvement in understanding accuracy. In this paper, I will look
both toward the past and the future, identifying and motivating the
decisions that were made in the design of TINA and ANGIE and the associated
rule formalisms, and contemplating various remaining open research
issues.
