Abstract:

In this informal seminar we first explain the basic trace projection algorithm used in ISIP's Trace Projection Decoder and describe some of the important implementation details. In order to efficiently handle large vocabulary tasks such as Switchboard, it is necessary that the next steps in the development of the trace projection decoder be towards incorporating lattices and using lexical pronunciation trees to generate cross-word triphones. We discuss the motivation behind this and propose an implementation for the trace projection decoder. This is followed by an open-house discussion on the related issues.
