ATIS0 Pilot is comprised of about four hours of spontaneous speech, read speech and other material from participants in the ATIS collection. Other corpora in the collection are: ATIS0 Read (LDC93S4B-2) and ATIS0 SD-Read (LDC93S4B-3)ATIS0 Complete (LDC93S4A) contains all three corpora.

The ATIS (Air Travel Information Services) collection was developed to support the research and development of speech understanding systems. Participants were presented with various hypothetical travel planning scenarios and asked to solve them by interacting with partially or completely automated ATIS systems. The resulting utterances were recorded and transcribed. Data was collected in the early 1990s at five US sites: Raytheon BBN, Carnegie Mellon University, MIT Laboratory for Computer Science, National Institute for Standards and Technology and SRI International.

ATIS0 Pilot contains spontaneous utterances elicited in a "Wizard-of-Oz" simulation, along with a relational database containing travel information (excluding connecting flights). In that data set, 36 speakers (24 male, 12 female) produced a total of 912 utterances.


ATIS speech data was recorded at 16kHz sample rate, 16-bit quantization, from two microphones: a close-talking (Sennheiser HMD414) and a desk-top (Crown PCC-160) model. Utterances were transcribed.
