Electropalatography
Electropalatography
Electropalatography (pronounced: e-lec-tro-pa-la-to-graphy) is a technique used in phonetics and speech pathology to measure the contact between the tongue and the hard palate during speech.
Etymology
The term 'Electropalatography' is derived from the Greek words 'electron' meaning amber, 'palatos' meaning roof of the mouth, and 'graphein' meaning to write.
Definition
Electropalatography (EPG) is a method that uses an artificial palate fitted to the speaker's mouth. This palate is embedded with numerous sensors that detect the contact between the tongue and the hard palate. The data collected is then used to create a dynamic visual representation of the tongue's movement during speech.
Usage
EPG is primarily used in the fields of phonetics and speech pathology. In phonetics, it is used to study the articulatory processes involved in speech production. In speech pathology, it is used to diagnose and treat articulatory disorders such as lisping and rhotacism.
