An interventional study of Ideal binary mask in Hearing Loss, Sensorineural and Dysarthria, sponsored by Utah State University. Completed at 1 site in United States. Open to participants aged 18 Years to 90 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-03-26.
Sponsored by Utah State University · Not applicable, Interventional, and Basic science
Dysarthria and hearing loss are communication disorders that can substantially reduce intelligibility of speech and the addition of background noise adds a further challenge. This proposal utilizes an established signal processing technique, currently exploited for improved understanding of speech in noise for listeners with hearing loss, to investigate its potential application to overcome speech-in-noise difficulties for listeners understanding dysarthric speech. Successful completion of this project will demonstrate proof-of-concept for the application of this signal processing technique to dysarthric speech in noise, and inform the development of an R01 proposal to perform a large-scale evaluation of the technology, and clinically meaningful implications, in a broad range of disordered speech types and severities.

Percent Correct Speech Intelligibility
Percent of keywords correctly identified by the participant for the processed speech stimuli, listeners were presented with phrases containing several words and they reported back what they heard. The number of words corrected reported by each listener was counted and converted to a 'percent correct' score.

Ran from Dec 2021 to primary completion in Dec 2023, 24 months.
Results were first posted in Mar 2025, 1 year 3 months after primary completion.
Of 82 non-industry interventional studies with no phase under Hearing Loss, Sensorineural, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 49. This study's 24 months is below that.
Counting every sponsor, half of 162 studies reached it within 22 months; a quarter within 6 and three quarters within 44.
