Experimental support for a model of birdsong production
In this work we present an experimental validation of a recently proposed model for the production of birdsongs. We have previously observed that driving the model with simple functions of time, which represent tensions in vocal muscles, produces a wide variety of sounds resembling birdsongs. In thi...

We have previously observed that driving the model with simple functions of time, which represent tensions in vocal muscles, produces a wide variety of sounds resembling birdsongs. In this work we drive the model with functions whose time dependence comes from recordings of muscle activities and air sac pressure. We simultaneously recorded the birds’ songs and compared them with the synthetic songs. The model produces recognizable songs. Beyond finding a qualitative agreement, we also test some predictions of the model concerning the relative levels of activity in the gating muscles at the beginning and end of a syllable. © 2003 The American Physical Society. 2003 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_1063651X_v68_n4_p_Mindlin http://hdl.handle.net/20.500.12110/paper_1063651X_v68_n4_p_Mindlin |
