Electropalatography，EPG) is used to monitor the contact position of tongue and palate in real time during pronunciation，Is an effective tool for collecting tip or surface consonants。The electronic bet365 live casino bettingpalate positioner of Shandong University Speech Laboratory is developed by RoseLinguaGraph EPG produced by the company。
1. Hardware system
EPG host、Hand gripper、Neck strap、Wristband、Signal transmission line、USB cable
2. Working principle
EPG determines the tongue-palatal contact position during pronunciation by using a custom-made electronic prosthetic palate with 62 electrodes。By sending weaker electrical signals to the subject，Conducted through the tongue to the electrodes in contact，Form a pathway，Storage bet365 online betting appthese tongue and palate contact signals。
(Insert Figure 2-1, Figure 2-2, Figure 2-3)
3. Signal collection
The subject wore an electronic prosthetic palate，Insert the electronic board connected to the prosthetic palate into the card slot of the EPG host，At the same time, insert one end of the electrode handle into the host interface，Transmit host signal to computer through USB cable。
(Insert Figure 3)
4. Data analysis
Analyze the electrical signals generated when the tongue contacts the prosthetic palate，Real-time presentation of the tongue-palatal contact pattern during bet365 best casino gamespronunciation，Obtain dynamic information about changes in tongue-palatal contact position over time。
(Insert Figure 4-1, Figure 4-2)
5. Application fields
Phonetics research: EPG can visually demonstrate the tongue-palatal contact pattern in speech production，Accurately locate the pronunciation parts of consonants in single words and co-articulation。
Visual speech teaching: Dynamic electronic palatal mapping can help language learners learn specific consonants in the target language through real-time visual feedback。
Speech Pathology: EPG can be used in the diagnosis of cleft palate disorder bet365 best casino gamesand dysarthria，And postoperative voice rehabilitation training。
