The Fearless Steps Challenge (FSC) initiative was designed to host a series of progressively complex tasks to promote advanced speech research across naturalistic "Big Data" corpora. The Center for Robuts Speech Systems at UT-Dallas in collaboration with the National Institute of Standards and Technology (NIST) and Linguistic Data Consortium (LDC) conducted Phase-3 of the FSC series (FSC P3), with a focus on motivating SLT system generalizability across channel and mission diversity under the same training conditions as in Phase-2. The FSC P3 introduced 10h of a previously unseen channel audio from Apollo-11 and 5h of novel audio from Apollo-13 to be evaluated over previously established and newly introduced SLT tasks with streamlined tracks. This paper presents an overview of the newly introduced conversational analysis tracks, Apollo-13 data, and analysis of system performance for matched and mis-matched challenge conditions. We also discuss the Phase-3 challenge results and evolution of system performance across the three Phases, and next steps in the Challenge Series.
