Week One Flashcards
Speech Chain; Articulatory Phonetics, & Anatomical Planes; Body Materials
What is sound?
Movement based sensation
Vibration that travels through a medium, such as air, water, or solids, as a waveform, detectable by the hearing sense in various organisms
What is the process of sound?
Vibration
Wave creation
Transmission
Interpretation
Explain vibration in regards to process of sound
An object vibrates, disturbing the particles in the surrounding medium
Explain wave creation in regards to process of sound
This disturbance causes the particles to move in a wave pattern
Explain transmission in regards to process of sound
Sound waves travel though the medium
Explain interpretation in regards to process of sound
Ours ears and brain process these waves
What pressure occurs in compression zones?
High pressure (peaks)
What pressure occurs in rarefaction zones?
Low pressure (valleys)
What if there was vibration that could not be heard? Is it still sound?
All speech includes vibration; therefore it involves sound
The magnitude of vibrations is below the threshold for sensation
What is the feed-forward model?
Linear process, a plan is constructed and carried out without paying attention to the results
What occurs during sensory processing?
Not about speech, unbiased approach to what has been received
Simply receive it, sense it, and decompose it
What is the feed-back model?
What you are saying is constantly going back to you and being monitored, have the ability to go back and correct self
Define haptic
tactile + proprioception
Define tactile
Related to touch, especially via skin
E.g., touching skin (think tactile sign language)
What is aero-tactile?
Sense of touch or feeling in relation to air or airflow
E.g., sensation of air moving against the skin
Define somatosensory
Perception of sensations such as touch, pressure, temperature, pain, and proprioception (process of perceiving)
Define proprioception
The sense of the relative position of ones own body parts
E.g., where is my hand now?
Define somatosensory response
Reaction or response of the somatosensory system to a sensory stimulus
E.g., moving hand away from hot stove
What is phonetics?
The scientific study of human speech sounds
What are the three branches of phonetics?
Articulatory phonetics
Acoustic phonetics
Auditory phonetics
What is articulatory phonetics?
How speech sounds are physically produced by the human vocal tract
What is acoustic phonetics?
Properties of speech from sound waves without regards to articulation
What is auditory phonetics?
How our brain processes acoustic phonetics
What anatomical structures provide the airstream in speech production?
Lungs, ribcage, diaphragm
