Explore advanced techniques for directly measuring articulatory movements during speech production in this 50-minute lecture from the Center for Language & Speech Processing at Johns Hopkins University. Delve into sophisticated methodologies used to capture and analyze the precise movements of speech articulators, including the tongue, lips, jaw, and other vocal tract structures. Learn about cutting-edge technologies and instrumentation employed in articulatory research, such as electromagnetic articulography, ultrasound imaging, and magnetic resonance imaging techniques. Examine how these direct measurement approaches provide crucial insights into the biomechanics of speech production, phonetic variation, and speech motor control. Discover the applications of articulatory data in understanding speech disorders, developing speech synthesis systems, and advancing theoretical models of speech production. Gain practical knowledge about experimental design considerations, data collection protocols, and analysis techniques specific to direct articulatory measurements, while understanding the advantages and limitations of various measurement technologies in speech research.
