“…The results concur with previous research studies which have found positive effects of using EPG in therapy (Gibbon, Stewart, Hardcastle, & Crampin, 1999;Carter, & Edwards, 2004;Dagenais, 1995;Gibbon & Wood, 2003;Gibbon, & Hardcastle, 1987). It should be noted that the investigators were only able to obtain data for two of the three participants 3 months post intervention.…”

“…Several studies have reported using EPG with children who presented with speech sound disorders (Carter & Edwards, 2004;Dagenais, Critz-Crosby, & Adams, 1994;Dagenais, 1995;Gibbon, 1999). Nordberg, Berg, Carlsson, & Lohmander (2008) study reported on two participants diagnosed with dysarthria secondary to dyskinetic cerebral palsy.…”

“…In Japan, the Rion Company, developed the DP01 EPG System. All these systems differed in their designs of the artificial palates, including the number and arrangement of electrode contacts and materials used (Dagenais, 1995;Gibbon and Wood , 2010). A new Windows® version of the Reading System was developed at Queen Margaret University, Edinburgh in 2008 and is still in use there today (Gibbon & Wood, 2010).…”

Purpose: This preliminary investigation examined the effectiveness of using electropalatography, manufactured by Complete Speech®, as a tool with three children diagnosed with articulation disorders. The participants produced the following phonemes in error: /ʃ/, /s/, /r/, r-colored vowels [ɚ,ɝ], and r-colored diphthongs [ɛr, ɪr, ɔr, ɑr] in different positions of words. Method: Speech and language skills were assessed prior to the intervention. A conversational speech sample was elicited and analyzed pre-and postintervention. The intervention consisted of a 45-minute session once a week over a 10-week period. Perceptual data were recorded during each session. Three months post intervention two of the three participant's speech was analyzed to determine possible generalizationof therapy targets. No home practice program was provided to the participants. Results: The results revealed that each of the participants improved in their lingua-palatal contacts for the phoneme(s) targeted. Conclusion: Electropalatography manufactured by Complete Speech® was a useful intervention tool to improve the speech skills of three children diagnosed with articulation disorders. Positive improvements in articulation as indicated in this study show promise for use ofthis software to improve patient awareness of articulatory errors and ability to use visual feedback to effectively produce target sounds and generalize their correct speech productions.

“…This technique has been used as a diagnostic assessment tool, for recording and analysing tongue contact patterns for sounds produced in the alveolar, post-alveolar, palatal and velar place of articulation (Friel, 1998;Gibbon, Dent, & Hardcastle, 1993;Gibbon, Hardcastle, & Dent, 1995). As a therapy tool, EPG has been used to target a range of speech production difficulties, including articulation/phonological disorders in children and young adults (Dagenais, 1995;Gibbon, McNeill, Wood, & Watson, 2003;Hardcastle, Gibbon, & Scobbie, 1995). It has been used increasingly to treat articulation/phonological disorders in children and adults with cleft palate (Whitehill, Stokes, & Man, 1996;Gibbon, Crampin, Hardcastle, Nairn, Razzell, Harvey, & Reynolds, 1998).…”

The efficacy of speech intervention using electropalatography with an 18-year-old deaf client: A single case study

This single case study explored the use of EPG as a therapeutic tool for treating inaccurate articulation of the voiceless alveolar plosive /t/. The participant (M) is an 18-year-old deaf adult who consistently uses hearing aids, and who communicates using a combination of English, Sign Supported English and British Sign Language (BSL). M received traditional phonological therapy targeting his production of /t/ prior to EPG therapy, but without success. He requested further therapy and EPG was offered as an alternative approach. Pre-EPG therapy, M made tongue placement errors for both /t/ and the voiced alveolar plosive /d/. Based on perceptual analysis by M's speech and language therapist, the first author, his productions were inconsistent, though generally perceived as voiceless and voiced velar plosives respectively. The EPG therapy consisted of 6 bi-weekly therapy sessions, each lasting for one hour, targeting M's production of /t/ in familiar words, using the visual feedback from the EPG display. Trained and untrained listeners perceptually analysed audio recordings of words and sentences collected at 3 assessment points. Improvements, both over the course of the EPG therapy and during the follow-up period, were found to be statistically significant. Significantly, M was able to generalise his production skills to untaught words containing both /t/ and /d/. Equally significant was the lack of change in M's production of a control sound, the voiceless dental fricative /θ/. More globally, an improvement was observed in ratings of M's intelligibility in sentences and in his voice quality (assessed impressionistically).

“…A few tongue-operated devices have been explored for use inside the oral cavity, such as a palatometer for electropalatography [19], IBM's Tonguepoint [20], NewAbilities' tongue touch keypad [21], and a tongue mouse [22]. These devices detect the pressure or force from the tongue, and thus may be utilized to send out message through silent and hands-free operation.…”

Abstract-An oral tactile interface was designed and evaluated to provide directional cues through the tactile channel, which may be utilized by a blind traveler to obtain directional guidance in outdoor navigation. The device was implemented as a mouthpiece with a microfabricated electrotactile display on top for tactile presentation onto the roof of the mouth and a tongue touch keypad at the bottom for simultaneous operation by the tongue. An experimental system allowed a user to communicate with a computer tactilely by using the oral interface. Directional cues were presented to the user as line or arrow patterns with four moving directions (leftward, rightward, forward, and backward). Electrotactile presentation on the roof of the mouth was evaluated in experiments of threshold measurement and identification of directional cues. Experimental results from six human subjects showed that the roof of the mouth required stimulation intensities around 15 V for threshold sensation, and around 25-30 V for comfortable and well-perceived stimulation. Furthermore, identification of leftward or rightward movements was highly accurate while performance on forward or backward moving patterns was mixed and varied considerably among subjects.
