Speech production begins in lungs: ***lungs give airstream for vocalization. Airstream flows up trachea via glottis (voice box) Recall: phonation (buzzing sensation in throat when saying ahh) Recall: vibrating objects make a fundamental frequency (perceived as pitch + overtones) Vibrating vocal folds (similarly) make fundamental frequency + overtones: resulting complex sound wave is the phonation that acts as raw material for speech production. Alveolar ridge: fleshy region of mouth covering bone where upper teeth are anchored, vip for consonants. Hard palate: behind alveolar ridge, bony region along roof of mouth. Velum (aka soft palate): behind hard palate. Blade: top surface of tongue (for snapping sound, unused in english) Consonants are made by blocking air flow through the mouth.
