Vocal tract imaging is a research field and set of methodologies concerned with the visualization and analysis of the anatomical structures and their dynamic movements within the human or animal vocal tract during vocalization. Utilizing various imaging modalities such as Magnetic Resonance Imaging, X-ray microbeam, ultrasound, or endoscopy, this approach provides crucial data for understanding the physiological processes underlying speech production, singing, and other vocal behaviors, informing research in phonetics, speech science, clinical diagnosis, and vocal performance.
