Electropalatography

Electropalatography (EPG) is a technique used to monitor contacts between the tongue and hard palate, particularly during articulation and speech.

[2] EPG provides dynamic real-time visual feedback of the location and timing of tongue contacts with the hard palate.

It can provide direct articulatory information that children can use in therapy to monitor and improve their articulation patterns.

Electropalatography was originally conceptualized and developed as a tool for phonetics research to improve upon traditional palatography methods.

[6] In some research, multiple repetitions may be summed to produce graphical representations of tongue-palate contact in a way that minimizes effects of random variation on single tokens.

[7] Three primary manufacturers of EPG tools exist: CompleteSpeech in the United States, Articulate Instruments, and icSpeech in Great Britain.

Completespeech is a private company that specializes in speech therapy oriented EPG tools, branded as The SmartPalate System.
