Abstract

Over the past 20 years, Dennis Klatt has made enormous contributions to the field of automatic speech recognition through his research, writing, and student supervision. In the early 70's, he served as a member of the steering committee of the ARPA Speech Understanding Research (SUR) program, providing leadership and guidance to the research community. He also participated actively in speech recognition research, first performing a set of spectrogram reading experiments assessing the role of various sources of knowledge, and later investigating the use of synthesis‐by‐rule techniques for word verification. Out of this involvement with the ARPA‐SUR program came the landmark paper reviewing its technical achievement. as well as several publications describing his own proposals, LAFS and SCRIBER, for human and machine speech recognition. Over the past 10 years, Dennis directed his attention to the design of signal representation front‐ends, as well as the investigation of perceptually motivated distance metrics in order to implement his speech recognition models. This talk pays tribute to Dennis's incredibly active research life by examining the legacy he left behind in speech recognition.
