Participant Flow
All participants were enrolled between January 21, 2022 and July 30, 2024. All participants were assessed and treated online using standardized headphones which were mailed to them prior to the onset of the study.
No significant events were encountered over the course of this study.
Participant milestones
| Measure |
Online Speech Perception Training
Participants will be randomly assigned to transition from the baseline to the treatment condition at one of 7 possible points, ranging from 3 to 9 baseline sessions. All participants will receive 12 sessions of perceptual training over 4 weeks. Finally, participants will complete a 3-session maintenance phase in which perception and production are probed but not treated. Perception will be measured using the identification and category goodness judgment.
Following completion of perception training all participants will complete two weeks of production training. The production training will consists of 4, 60-minute sessions. Each session will provide instruction and practice trials.

Online Speech Perception Training
n=10 Participants
Participants will be randomly assigned to transition from the baseline to the treatment condition. All participants will complete the assigned # of baselines sessions in which perception and production probes are elicited. All participants will then receive 12 sessions of perceptual training over 4 weeks, followed by 4 stimulability production training sessions. Participants will complete a 3-session maintenance phase in which perception and production are probed but not treated.

SECONDARY outcome
Timeframe: Participants' progress was tracked across pre-treatment phase (averaged baselines) compared to post treatment phase (averaged three maintenance sessions which occurred over 1 week), up to 8 weeks, including baselines, treatment, and maintenance sessions.Represents the raw change in percent accuracy on the perception task, calculated as the difference between the average pre-training accuracy score and the average post-training accuracy score.
