Jan 8 - Speech Chain: Articulatory Phonetics Flashcards
what is sound?
Sound is essentially the result of vibrations, when an object vibrates, it causes the air particles around it to move, creating sound waves.
what is the process of sound?
- Vibration: an object vibrates, disturbing the particles in the surrounding medium.
- Wave Creation: This disturbance causes the particles to move in a wave pattern.
- Transmission: Sound waves travel through the medium.
- Interpretation: Our ears and brain process these waves.
The cummings 2008 speech chain is what kind of modal and why?
- The process is linear (unidirectional)
- It is a feed-forward system.
What are the steps of a feed-forward model
- Thoughts to acoustics
- Acoustics to thought
Definition: Haptic
Tactile + Proprioception
Definition: Tactile
related to touch, especially vis skin
- aero-tactile: sense of touch or feeling in relation to air or airflow
- e.g., sensation of air moving against skin.
Definition: somatosensory
perception of sensations such as touch, pressure, temperature, pain, and proprioception.
Definition: Proprioception
the sense of the relative position of ones own body parts
Definition: Somatosensory response
reaction or response of the somatosensory system to a sensory stimulus.
- e.g. perception of warmth, cold, or pain, leading to a deliberate action like moving hand away from hot object.
What is phonetics
Phonetics is a scientific sutdy of human speech sounds
What are the 3 branches divided into three branches
- articulatory phonetics
- acoustic phonetics
- auditory phonetics
What do the lungs, ribcage, diaphragm do?
Provide airstream.
what do the vocal folds/larynx do?
Vibrate to produce sound
What do the articulators do?
Include the tongue, teeth, lips, and palate, shaping the sound into speech.
How are vowels characterized?
- Tongue Height
- Tongue backness
