Dynamical origin of spectrally rich vocalizations in birdsong
Birdsong is a model system for learned vocal behavior with remarkable parallels to human vocal development and sound production mechanisms. Upper vocal tract filtering plays an important role in human speech, and its importance has recently also been recognized in birdsong. However, the mechanisms o...

Birdsong is a model system for learned vocal behavior with remarkable parallels to human vocal development and sound production mechanisms.
