Order from Lab 7A3628

ATC radio speech

Air traffic control radio audio with verbatim transcripts timed per transmission and reviewed by licensed pilots, with overlapped, stepped-on and blocked transmissions labeled. It must be real off-air recordings from many facilities, with lawful recording rights per country and commercial training rights.

How answering works

Any number of people fill one order. The lab receives one dataset, in its own columns.

Your agent reads the order
It looks at what you hold and says which columns you can fill, and what is missing.
Mora checks what you send
Every record: no copies, no personal data, not already public, not on Mora from someone else.
The lab pays per record it accepts
The lab named the price. You fill as much of the order as you can.

The columns the lab wants

You do not need every column. Mora says which ones each dataset fills.

Column Type What it must hold

clip_id id One recorded stretch of one channel

audio audio (WAV or FLAC, mono, 16-bit, native The off-air recording, never re-encoded from MP3

facility_icao text ICAO code of the airport or centre

position label Ground, tower, approach, centre or ATIS

frequency_mhz number The radio frequency recorded

receiver_id id Which receiver captured it, so the same transmission heard twice can be spotted

recorded_at UTC timestamp Start of the clip to the second

duration_s number Clip length

keyed_speech_s number Seconds of actual speech in the clip, without squelch silence

tx_id id One row per transmission

start_s number Transmission start, within 200 ms

end_s number Transmission end, within 200 ms

speaker_role label Pilot, controller, vehicle or ATIS

speaker_id id A stable generated id per voice

text_verbatim text Words exactly as spoken, including 'tree', 'niner', hesitations and unintelligible marks

text_normalised text The same with numbers and callsigns normalised

callsign_spoken text The callsign as said, kept as it is

callsign_icao text The callsign in ICAO form

overlap_kind label None, stepped on, blocked (heterodyne), simultaneous or partial

overlap_with id The other transmission involved

recoverable label Which party can still be understood

transcribed_by label Human, or machine first pass then human

reviewer_id id Generated id of the pilot who reviewed

reviewer_credential label Licence class and issuing authority of the reviewer

second_reviewer_id id Second pilot on the double-reviewed subset
