Air Traffic Controller Radiotelephony Fatigue Corpus

This corpus was obtained from the Air Traffic Management Bureau, Civil Aviation Administration of China (CAAC). All speech had been recorded from December 15, 2020 to January 14, 2021. The raw data comprised around 700,000 segmentsof air traffic control speech involving all work stations over 3 daily periods (0200–0700, 1000–1200 and 1330–1530 hours). Seven controllers with different genders, age groups, controller levels and control positions were identified. Their working speech records were then selected from the raw data and preprocessed. Additionally, based on the standard principle of radiotelephony, one specific speech utterance was cut from the entire speech record that contained speech from both pilots and ATCs with the help of software that analyzes semantic context (GoldWave). Moreover, signal preprocessing techniques such as pre-emphasis, framing and windowing were utilized to improve the quality of the speech samples.
