Electropalatography
Electropalatography (often abbreviated as EPG) is a technique used in phonetics and speech pathology that allows for the examination of consonant and vowel articulation during speech production. This technique uses a custom-made artificial palate fitted with an array of sensors to detect contact between the tongue and the palate.
History[edit | edit source]
The concept of electropalatography was first introduced in the 1970s by a team of researchers at the University of Reading. The initial design was a hard palate with embedded electrodes, which was later replaced by a more flexible design with embedded sensors.
Procedure[edit | edit source]
The procedure for electropalatography involves the creation of a custom-made artificial palate that fits the individual's mouth. This palate is fitted with an array of sensors that can detect contact between the tongue and the palate. The data collected from these sensors is then analyzed to provide information about the individual's speech production.
Applications[edit | edit source]
Electropalatography has a wide range of applications in both research and clinical settings. It is used in the study of various aspects of speech production, including the articulation of consonants and vowels, the timing of speech movements, and the coordination of the tongue and other articulatory organs. In clinical settings, it is used to diagnose and treat speech disorders, such as articulation disorders and speech sound disorders.
Advantages and Disadvantages[edit | edit source]
One of the main advantages of electropalatography is that it provides detailed information about the articulatory processes involved in speech production. It allows for the examination of the timing and coordination of speech movements, which can be useful in diagnosing and treating speech disorders.
However, there are also some disadvantages to this technique. The process of creating a custom-made artificial palate can be time-consuming and expensive. Additionally, the presence of the artificial palate in the mouth can affect the individual's speech production, which can make it difficult to obtain accurate data.
