Introduction

ATIS0 Complete is comprised of spontaneous speech, read speech and other material from participants in the ATIS collection that is contained in the following corpora: ATIS0 Pilot (LDC93S4B), ATIS0 Read (LDC93S4B-2) and ATIS0 SD-Read (LDC93S4B-3).

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 produced a total of 912 utterances.

ATIS0 Read contains "read" versions of the spontaneous utterances for 20 of the 36 speakers above, for a total of 478 productions. This is supplemented by a set of 40 "adaptation" sentences read by each of the 20 speakers.

ATIS0 SD-Read contains "read" speech in the ATIS domain for ten of the speakers in ATIS0 Pilot consituting 3,171 utterances, or approximately 317 utterances per speaker.

Data

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.
