Abstract
The paper introduces the motivation for creating dedicated speech corpora of air traffic control communication, describes in detail the process of preparation of corpora for both automatic speech recognition and text-to-speech synthesis, presents an illustrative example of speech recognition system developed using the automatic speech recognition corpora and finally describes the technical aspects of the data and the distribution channel.

Notes
Which, in our case, does not in fact mean “high quality”—see the following sections.
Although the ATC communication can be conducted in native language in regional air traffic, the use of English is naturally indispensable in international ATC.
See for example http://aviationknowledge.wikidot.com/aviation:nato-phonetic-alphabet.
Note that the assumption that we know the origin of the data is perfectly reasonable—in our “artificial pseudopilot” scenario, we also only expect the controller’s speech.
