Using 10 kindergarten children with poor articulation of /s/, this study sought to determine whether modification of speech sounds by the use of an electroacoustic filter improved the children's /s/ articulation, as compared to training of /s/ using non-filtered words. Posttest scores, as measured by "A Deep Test of Articulation," showed a significant improvement for some members of the experimental group over their pretest scores, while the control group made little or no improvement. The study was intended to encourage speech-language pathologists and researchers to explore the potential effectiveness of such a filter in remediation training of misarticulated sounds. A list of suggestions for future research is provided. (JDD)
