Document Summary
Larynx - prevents food, water, dust from entering lungs. Thyroid cartilage - front- when you say ba that is what you can feel vibrating. Laryngeal sound production - vibration of vocal folds -- speech, laughter, cough. For speech - lips (main one), teeth, ridge behind upper teeth, soft and hard palate. Females v males - sound is conceived differently (females = 225, males = 125 cycles per second) Children have highest fundamental frequency out of everyone. Pitch and loudness - males have thicker vocal folds (pitch) and more pressure, the more loudness variations an individual can have. Resonance - shape of oral and pharyngeal cavity modify sound wave - source filter theory. Oral cavity - separate from nasal cavity due to soft palate (soft palate separates them) Larynx to top of mouth/nose - where articulators are found. Articulator movement is the reason why consonant sounds are different. Sound filter - where is the sound made meaningful.
