In-Depth Information
In addition, a number of cross-transcriber reliability evaluations have been
completed on the CU-Move corpus. Three transcribers were on the average,
in agreement the majority of the time for parts 1-4 (prompts), with a 1.8%
substitution rate when comparing transcriber hypotheses two at a time. When
we consider the spontaneous route navigation WOZ part, transcriber files
naturally had a higher difference, with a substitution rate of 3.0%. These
numbers will depend on the clarity and articulation characteristics of the
speakers across the six CU-Move dialect regions.

In this section, we discuss the formulation of our microphone array
processing
front-end, environmental sniffing, robust
speech recognition
system, and proto-type dialogue system.
