palatogrophy/lingual consonants Flashcards
what generally is palatogrophy
Method to study tongue–palate contact during speech
whats the normal expensive version
electropalatography, (EPG): bring in your participant, ask them to bite on a cast, bring to technicians to make a specific palate. then participant puts on the palate (with the electrodes in there) and they talk
whats the cheaper version
static palatogrophy
Uses powder or dye to mark tongue–palate contact
static palatogrophy is most useful for stop ____ and ____
consonants, affricates
static palatogrophy advantages/disadvantages
Advantages
▶ Simple and inexpensive
▶ Good for single articulatory events
Limitations
▶ Not dynamic — only captures one moment
▶ Messy and intrusive
EPG advantages and limitations
Advantages
▶ Real-time dynamic analysis
▶ Repeatable and quantifiable
Limitations
▶ Expensive and requires custom palate
▶ Only records contact, not pressure
in terms of lingual consonants, ____ probbaly have least amount of tongue manip.
bilabials
what are 3 functions of tongue bracing in speech
stability/precision
efficient speech production
feedback for adjustment
mediall bracing happens at the ___ ____ with the tongue ___
alveolar ridge
tip
in lateral braces tongue makes contact with the ___
molars
Which type of bracing is more prevalent in speech you think?
A. Medial bracing
B. Lateral bracing
C. Both are approximately the same
B
lateral sounds use __ bracing, medial sounds use __ bracing
medial, lateral
____ would require a lot of overshoot
ejectives
__/__ have little to no overshoot
flaps/taps
can stops and taps be prolonged?
stop sounds can be prolonged,
* taps cannot be prolonged. ex [butter] you cannot sustain the [t]
The ___ ____ muscle facilitates retroflex productions.
superior longitudinal
bunching in retroflex sounds happens at the tongue tip/root
root
EPG might not be the best choice for ___ sounds
dental
- for static palatography, ___ are hard
velars
English vs Spanish /p/ - in ___ it takes more pressure build up
english
in labialdental fricatives should you maintain a complete seal
no, it would stop the airflow completely
what is an Electromagnetic Articulometer (EMA) used for?
It uses ____ and ___ ____ to capture the position and motion of objects
to track and record the movements of speech articulators
in real time.
sensors, magnetic fields
does EMA have high or low temporal resoluaion? how often are measurements taken?
high, every 10ms at least
Which of the following sets of speech sounds involves constrictions that can be reliably studied using electropalatography (EPG)?
[s, z]
[m, b]
[a, i]
[q, R]
[s, z]
Even though static palatography/linguography is a very low-tech method, it can be reliably used to determine whether a speaker curls their tongue tip backward when producing a retroflex stop.
True
False
true
