A new segmentation method of bird vocalisations recorded in the distance: Development of recognition software using multi-CPU

摘要

The introduction of the ornithological spectrographrnin the 1950s changed the way birdsongrnwas measured, quantified, and interpreted byrnbiologists. The spectrograph was correlated withrnobjective knowledge and quickly supersededrnsubjective aural assessment. Over the past 15rnyears, we have used advanced LPC (Linear PredictivernCoefficient) spectrography to developrnand update automated detection and recognitionrnsoftware for bird vocalisations.
