This paper introduces a common database and an evaluation framework for connected digit speech recognition in real driving car environments, CENSREC-2, as an outcome of IPSJ-SIG SLP Noisy Speech Recognition Evaluation Working Group. Speech data of CENSREC-2 was collected using two microphones, a close-talking microphone and a hands-free microphone, under three car speeds and four car conditions. CENSREC-2 provides four evaluation environments which are designed using speech data collected in these car conditions.
