Electropalatography

 

An Electropalatograph ( EPG for short or also termed palatometer in the US) is an instrument that records the timing and location of tongue contact with the hard palate during speech.
The technique requires the speaker to wear an artificial palate that is moulded to fit the roof of the mouth.
Tongue-palate contact is recorded by a number of silver or gold contacts located on the lingual surface of this artificial palate (also termed pseudopalate).

EPG can be used as an aid to help a speech and language therapist diagnose disordered speech  and provide visual cues during therapy.

EPG is also used by phoneticians as a tool for studying typical (or indeed disordered) speech in a research setting

I am interested in finding out about EPG in clinical practice

I am interested in EPG for phonetic research
