Elemans, C.P.H., Muller, M., Larsen, O.N.
Birdsong has developed into one of the important models for motor control of learned behaviour and shows many parallels with speech acquisition in humans. However, there are several experimental...
Spectrogram analysis of animal sound production (2008)
Elemans, C.P.H., Heeck, K., Muller, M.
Spectrograms visualise the time-frequency content of a signal. They are commonly used to analyse animal vocalisations. Here, we analyse how far we can deduce the mechanical origin of sound generation...
Syringeal muscles fit the trill in ring doves (Streptopelia risoria L.) (2006)
Elemans, C.P.H., Spierts, I.L.Y., Hendriks, M., Schipper, H., Müller, U.K.
In contrast to human phonation, the virtuoso vocalizations of most birds are modulated at the level of the sound generator, the syrinx. We address the hypothesis that syringeal muscles are...
Modelling bird songs: Voice onset, overtones and registers (2006)
Zaccarelli, R., Elemans, C.P.H., Fitch, W.T., Herzel, H.
We analyze two symmetric two-mass models of the avian syrinx. Our first model applies to songbirds and is a rescaled version of the well-known human two-mass model. Our second model (trapezoidal...
Superfast muscles control dove's trill (2004)
Elemans, C.P.H., Spierts, I.L.Y., Müller, U.K., Goller, F.
Bird songs frequently contain trilling sounds that demand extremely fast vocalization control. Here we show that doves control their syrinx, a vocal organ that is unique to birds, by using superfast...
