We describe a large audio-visual speech corpus recorded in a car environment, as well as the equipment and procedures used to build this corpus. Data are collected through a multi-sensory array consisting of eight microphones on the sun visor and four video cameras on the dashboard. The script for the corpus consists of four categories: isolated digits, isolated letters, phone numbers, and sentences, all in English. Speakers from various language backgrounds are included, 50 male and 50 female. In order to vary the signal-to-noise ratio, each script has five different noise conditions: idling, driving at 35 mph with windows open and closed, and driving at 55 mph with windows open and closed. The corpus is available through .
