Vocal Tract Articulation in Zebra Finches
BACKGROUND Birdsong and human vocal communication are both complex behaviours which show striking similarities mainly thought to be present in the area of development and learning. Recent studies, however, suggest that there are also parallels in vocal production mechanisms. While it has been long thought that vocal tract filtering, as it occurs in human speech, only plays a minor role in birds...
متن کاملMechanisms of Vocal Coordination in Zebra Finches
Social animals frequently emit communication calls. Although these calls are often innate in their acoustic structure, they can be used adaptably to coordinate behavior with other individuals. It is not known, however, what each animal needs to learn in order to achieve and maintain synchronized call patterns with others. To study this process, we have developed a vocal robot that can be progra...
متن کاملVocal-Tract Filtering by Lingual Articulation in a Parrot
Human speech and bird vocalization are complex communicative behaviors with notable similarities in development and underlying mechanisms. However, there is an important difference between humans and birds in the way vocal complexity is generally produced. Human speech originates from independent modulatory actions of a sound source, e.g., the vibrating vocal folds, and an acoustic filter, form...
متن کاملArticulation and Coarticulation in the Lower Vocal Tract
This proposal is aimed at understanding the strategies that are used to control articulators during speech and at clarifying the relationships between phonological features and articulatory motions. This experimental project involves the collection and analysis of Magnetic Resonance Imaging (MRI) and acoustic speech data, combined with numerical modelling of articulatory motions. Movements of t...
متن کاملVocal tract articulation revisited: the case of the monk parakeet.
Birdsong and human speech share many features with respect to vocal learning and development. However, the vocal production mechanisms have long been considered to be distinct. The vocal organ of songbirds is more complex than the human larynx, leading to the hypothesis that vocal variation in birdsong originates mainly at the sound source, while in humans it is primarily due to vocal tract fil...
