*ELDA releases air-traffic control data from ATCO2 Project*

ELDA is pleased to announce the release of ATCO2 Project Data.ATCO2 project collected the real-time voice communication between air-traffic controllers and pilots available either directly through publicly accessible radio frequency channels or indirectly from air-navigation service providers (ANSPs). In addition to the voice communication data, contextual information is available in a form of metadata (i.e. surveillance data).

The dataset consists of two subsets:

* a corpus of more than 4000 hours with untranscribed data * a corpus of 4 hours with transcribed data of air-traffic control speech collected across different airports (Sion, Bern, Zurich, etc.). Ca. 1 hour of annotation has followed a human re-checking.

The datasetcan be found in the ELRA Catalogue of Language Resources under the following links and references:
