A speech-language pathologist with thousands of endoscopies shows you the real anatomy behind twang, ring and warmth — with live MRI and scope footage.

Kerri Obert, a speech-language pathologist and singing voice specialist with nearly 30 years in voice disorders clinics, takes you inside the pharynx with her own MRI and endoscopy footage. You'll learn the three ways to shape the space above the larynx: larynx height (and why a high larynx is not automatically dangerous), anterior-posterior narrowing using the back third of the tongue, and lateral-medial narrowing by the pharyngeal constrictors — the true source of twang. She explains how the pyriform sinuses and valleculae cancel high-frequency energy, demonstrates each setting against commercial recordings, and gives you teaching cues: Kermit, Julia Child, Dracula, quacking, and the "big squint."
