Resumen:
Songbirds are the best-suited animal model to study general mechanismsunderlying learned motor behavior responsible for complex output, asit is birdsong. Between the central motor pattern generator and thecomplex output stands a highly nonlinear biomechanical periphery. Theavian vocal organ of the Zebra Finch (Taeniopygia guttata) is capableof generating a large variety of acoustic signals, which range fromsimple whistles to highly complex sounds.A mathematical model of the zebra finch syrinx is proposed, in whichthe onset of labial oscillations and the acoustic features of thesound are tuned by parameters accounting for the bird´s motorpatterns. We build an electronic birdsong synthesizer by implementingthe model in a Digital Signal Processor (DSP). This device is capableof reading physiological recordings, integrating the mathematicalequations representing the avian vocal organ´s behavior, and producingsynthetic birdsong in real time.
