SLP Corner: Online Crowdsourcing a Potential Tool for Speech Therapy Research
[Source: Education Week.org]
Research into speech therapy interventions usually requires trained listeners to evaluate a student’s progress by listening to his or her speech and rating the sounds for correctness, but ratings from speech language pathologists can be costly to obtain and take a long time to gather.
Enter the world of crowdsourcing. A study published in the January/February edition of the Journal of Communication Disorders finds that the aggregated opinions of nine untrained listeners recruited through a crowdsourcing platform can provide equally valid assessments compared to the averaged results of three trained listeners.
The findings could help speech researchers, who in turn could be able to develop interventions more quickly, said the authors of the study, who are all based at New York University.
And eventually, crowdsourcing could become a tool for speech pathologists as well, who could use crowdsourcing both to evaluate student’s intelligibility and to gauge that student’s progress in therapy by using unbiased listeners, said Tara McAllister Byun,the study’s lead author and an assistant professor in the university’s department of communicative sciences and disorders.
“We do hope, in the future, that it could be easy to upload sound samples so that a speech pathologist could keep track of how they’re doing,” Byun said.
Speech and language disorders are second only to learning disabilities in the percentage of students who are receive services under the Individuals with Disabilities Education Act. About 18 percent of students were in this category in 2011-12, the most recent year for which statistics are available (learning disabilities accounted for about 40 percent of students served under IDEA that year.) For young children, speech and language disorders were more prevalent—about 45 percent of children ages 3 to 5 who received special education services did so for some kind of speech impairment.
