In this paper, we present our recent work in the analysis and formulation of a new acoustic speech corpus for developing in-vehicle interactive systems for route planning and navigation. The CU-Move Corpus development is partitioned into two phases: [I] acoustic noise collection and analysis across vehicles, and [II] data collection consisting of +1000 speakers from across the United States. We present results from Phase I acoustic noise data analysis across vehicles to determine guidelines for Phase II large-scale data collection using a single vehicle type. A total of 14 noise conditions are identified for analysis across 6 vehicles. We also present our plan for Phase II collection including speakers, dialect regions, data collection hardware, prompts and dialog domains. Since previous studies in speech recognition have shown significant loses in performance when speakers are under task stress, it is important to develop conversational systems that minimize operator stress for the driver. This will be the first U.S. based corpus of its kind consisting of multi-channel data, intended for use in developing mixed-initiative dialog speech systems; the initial application being route planning and navigation through a wireless information retrieval sub-system connected to the WWW.
