Document Summary
Speech anatomy and physiology: respiratory system as power supply, develops relatively constant pressures that will be used to create vocal fold vibration, and momentary changes in pressure required for linguistic stress. The vocal folds vibrate at different rates for men, women, and children, and their rate of vibration determines the pitch of the voice. Best way to think about the vocal tract is a flexible tube that can be shaped in various ways by the articulators for different kinds of speech sound production. Speech acoustics and perception: source-filter theory, resonant frequencies of vocal tract distinguish different vowels, acoustic phonetics. Phonological development and disorders: normal speech sound development, model of phonological development (receptive side, production side, both. Developmental difference?: possible causes of phonological disorders. Neurological bases of communication disorders: broca"s and wernicke"s areas: lateralization of language, anterior vs. posterior lesions/production vs. perception deficits, the cranial nerves control the muscles of the head and neck.
