Pick-by-Voice has been the main voice application in warehouses for over 20 years. Today voice covers the whole warehouse, from receiving to shipping. Voice-directed solutions reduce picking errors, improve customer satisfaction and ergonomics, and lower your carbon footprint.

How voice picking works
Request an order
The picker asks for a new order by voice and hears the location of the first product.
Confirm the location
The picker reads the check digit of the storage location, so picks from the wrong place are caught at once.
Pick the quantity
The system tells the quantity, and the picker confirms the number of items placed on the carrier.
Repeat and ship
The cycle repeats until the order is complete and sent to shipping.
Batch picking enhances operations
Batch picking works best for small orders with few lines and small quantities. Combining them into larger batches reduces picking errors and increases efficiency.
Cross-docking – hectic moments in order handling
Cross-docking terminals are busy, and supply-chain errors are costly. Supplier pallets are not stored but routed to a dispatch area and split into individual customer deliveries.
Terminals often handle dozens of pallets and thousands of orders, so the work must be both fast and accurate. Voice picking keeps the picker’s eyes on the pallets and confirms every step – exactly what cross-docking needs.
Picking list display brings optimum picking order
A 3PL’s range can go from cement sacks to furniture and from crowbars to fluorescent lamps. A touchscreen on the forklift or picking cart lists all order lines, so pickers can put heavy and bulky items at the bottom of the pallet and fragile or small items on top. Large quantities can be split across batches and pallets. Voice keeps work hands-free and eyes-free, while the display lets pickers use their expertise – for well-packed pallets that survive the delivery route.

Voice picking compared with paper lists and handheld scanning
| Paper pick lists | Handheld scanning | Voice picking | |
|---|---|---|---|
| Hands and eyes | Hands hold the list, eyes move between list and shelf | One hand holds the device, eyes on the screen | Hands and eyes free for the work |
| Error checking | Manual, after the fact | Barcode scan per pick | Check digit per location and spoken quantity confirmation |
| Real-time visibility | None until the list is returned | Yes | Yes – supervisors see progress and order status |
| Training | Fast, but working methods vary | Moderate | Fast – the system tells the picker what to do next |
| Best fit | Very small volumes | Processes that need scanning of every item | High-volume case and batch picking, cold stores, cross-docking |
Voice and scanning can also be combined: for example, voice for picking and a scanner for serial numbers or batch codes.
