Advantages of Electropalatography Sensor

Advantages of Electropalatography Sensor:-

  1) EPG has the facility to provide visual feedback of tongue-palate contacts. The     tongue position is placed on the computer screen and flashing lights indicate the   electrode the tongue touched.
      2) It records alveolar, post-alveolar, palatal, velar placement, and registers specific
            characteristics for consonants.
  3)   The EPG allows objective assessment and provides a dynamic visual presentation
        of articulatory goals that are normally not seen.
  4) EPG can contribute to the diagnosis of speech disorders by revealing information relevant to underlying deficits, information not available from transcription-based analyses.
  5) The strategy of the system is to compare the patterns of tongue contact for a pathological speaker with a normal speaker and interpret the differences.
  6) The ultimate goal of the therapy is to have the user produce the sounds in all contexts without the pseudopalate and without visual feedback.
  7) If these goals are accomplished the subject is well on their way to overcoming their speech difficulties.

      Disadvantages of Electropalatography Sensor:-

  1)   Financial constraints, these palates are very expensive and must be manufactured for each child.   Their period of use is also limited because children grow and it will make them useless.
  2) Additional hardware is required including a personal computer and software for proper treatment of these disorders.
  3) Access to these techniques is limited and can only be found in a few centers.
      Proper training is essential in using these methods effectively, while assisting in           EPG data interpretation.

      Cochlear Implant User - A Case Study:-

      1) A 8.9 year-old girl was referred for remediation of her velar stop consonant production. Child had a profound bilateral sensory-neural hearing loss present from birth.   Child was given a cochlear implant three...
