Title: The Symbiosis of DSP and Speech Recognition or an Outsider's View of the Inside

Abstract: From an historical review of how we got to where we are now, we discuss the interrelationship between our system design objectives and goals, our modeling of the speech signal and its generation and parameterization, and the broadly developing DSP methodology. We take a critical look at some of the underlying assumptions in our modeling to see if they may be limiting the performance that can be obtained with ASR systems. We close with some open questions and challenges for new work.
