Analysis of prosodic and spectral properties of voice communication in air traffic control
Simonides, Jakub ; Kopřiva, Tomáš (referee) ; Smékal, Zdeněk (advisor)
This thesis analyses the prosodic and spectral features of bi-directional air traffic control communication, describes how to communication was split to segments, according to the source, via transcription. After the splitting, the segments are deeply analyzed for their spectral and prosodic features. The analysis itself, focuses on the spectral aspects of intensity, fundamental frequency F0, slope and centroid. Additionally, tempo and voice activity detection data were measured, to support the spectral aspects as well. Because of the differences between the ATC controller’s and pilots’ spectral aspects, the direction of the communication can be automatically determined, with relatively high success percentage.
