Increasing Warehouse Worker Performance Using Voice Technology that Provided Immediate Feedback: Personal Performance Productivity Prompt
A two-second audio recap of ‘units per hour’ pushed warehouse pickers above company speed goals.
01Research in Context
What this study did
Goomas (2023) added a short audio cue to the headsets warehouse pickers already wore. After each pick, the system said the worker’s current units-per-hour rate.
The study ran in a live distribution center. No extra staff or devices were needed. The voice software simply spoke the number.
What they found
Order selectors immediately moved faster. Their hourly rate met or beat the company labor standard once the prompt was on.
When the prompt stopped, speed dropped back to baseline, showing the cue was the key change.
How this fits with other research
Thomas et al. (2026) reviewed 35 studies and found brief auditory feedback works in almost every setting. The warehouse cue is one more data point in that winning column.
Sleiman et al. (2020) pooled 96 workplace feedback cases and saw large gains across the board. The voice prompt lines up with those strong averages.
Luna et al. (2026) tried AI video clips for factory posture. Both studies use instant tech feedback to lift adult worker performance; only the sense channel differs—eyes versus ears.
Why it matters
You can squeeze more output from the same staff without new hires or bigger bonuses. If your learners already wear voice gear, ask IT to append a quick ‘units per hour’ line after each task. Turn it on for one shift, graph the rate, and you have an instant demo of feedback power.

03Original abstract
This research report examined the use of a voice-directed warehouse management system (WMS) to increase worker performance in a large industrial setting. Order selectors in distribution centers that use voice-directed systems (listening to instructions via a headset and speaking into a microphone and receiving immediate audio feedback) were tracked for units per hour performance of products selected for store orders. The voice-directed application was enhanced with a personal performance productivity prompt so that each order selector now heard their units per hour performance after each completed store order assignment. Upon activation of the newly developed personal performance productivity prompt, selector performance increased to match and exceed the labor standards established for three warehouse zones (accessories, batteries, and tires). This is an example in which an Organizational Behavior Management (OBM) professional can play a vital role in helping large industrial settings adapt to new technologies for the workforce, in this case, for increased performance.
