The ATIS (Air Travel Information Services) collection was developed to support the research and development of speech understanding systems [1]. The original English data includes intent and slot annotations, and was later extended to Hindi and Turkish [2]. MultiATIS++ futher extends ATIS to 6 more languages, and hence, covers a total of 9 languages, that is, English, Spanish, German, French, Portuguese, Chinese, Japanese, Hindi and Turkish. These locales belong to a diverse set of language families- Indo-European, Sino-Tibetan, Japonic and Altaic.

MultiATIS++ corpus has been outsourced to foster further research in the domain of multilingual/cross-lingual natural language understanding.
