Introduction: Speech errors and associated oral sensory difficulties in ASD subjects are principally related to lack of synchronization between oral sensory –motor receptors, and incomplete motor planning. However, current speech therapy works on imagination and simulation. Hence, there is a need of the SSD which stimulates an oral sensory-motor receptors for better speech and decrease proportion of associated oral sensory difficulties.

Methodology: The study was conducted by randomly selecting 10 ASD children between the age group of 4-15 years. The five children received routine speech therapy and in other five children, SSD device was used followed by speech therapy. Speech therapist was blind for which child used SSD device. SSD device is a programmable microcontroller vibrator device. it comprises of a plurality of vibrators in order to create multiple vibrations of vibration patterns for stimulation of oral sensory region. Each vibrator is connected to pulse width modulation pin of the microcontroller which allows frequency of vibrator to desired range. Pre-speech recording before therapy and post-speech recording after therapy with recording graph in both the subjects have been used for comparison.

Result: ASD subjects showed more clarity is speech particularly articulation and phonological error by using the SSD device followed by speech therapy than speech therapy alone. Associated sensory difficulties such as inappropriate feeding behavior, biting on object, attrition, and drooling saliva reported with less proportion in SSD device group.

Conclusion: SSD device improves the speech articulating and phonological errors, improve feeding and eating behavior, reduces the severity of attrition and biting on object.
