Voice Picking
Definition
Voice picking is a hands-free, eyes-free warehouse method where workers wear a headset that speaks pick instructions and listens for spoken confirmations, communicating with the WMS in real time.
In Practice
The system tells the worker where to go ('Aisle 12, slot 47'), the worker reads back a location check digit to prove they are at the right spot, and speaks the quantity picked. With both hands and eyes free, workers handle cases faster and more safely than while juggling a scanner or paper.
Voice dominates full-case grocery and beverage picking, where heavy items, gloves, and freezer environments make scanners awkward. Accuracy comes from the spoken check digits; productivity gains of 10-25 percent over paper are typical, along with faster training since the device speaks the worker's own language.
Example: a grocery DC's freezer pickers assemble 1,000-case store orders by voice; gloved and moving constantly, they confirm each location verbally, and shorted or mispicked cases drop sharply versus label-based picking.
