The results indicate that sensations from the jaw and vocal tract alone can be used for speech learning. (sciencemag.org)
In the current study we used X-ray cinematographic imaging of naturally vocalizing monk parakeets (Myiopsitta monachus) to assess which articulators are possibly involved in vocal tract filtering in this species. (jeb.biologists.org)
Clearly, there is increasing evidence for the importance of vocal tract filtering in the production of avian vocalizations. (jeb.biologists.org)
