Pick-by-Voice in the Warehouse: How Voice-Guided Order Picking Works

Pick-by-Voice, also known as voice picking, is a paperless order-picking system connected to a warehouse management system (WMS).

The WMS sends picking orders to the voice system in real time. The employee receives instructions through a headset, such as:

• Which storage location to visit
• Which product to pick
• How many items to pick

The employee then confirms each step verbally before receiving the next instruction.

Unlike traditional paper-based picking or scanner-assisted picking, there is no need to read a list or repeatedly operate a handheld device. This creates a continuous workflow and allows employees to keep their hands and attention on the picking task.

Modern voice systems can also support multiple languages and individual voice profiles, which can make them easier to introduce across diverse warehouse teams.

Voice-guided order picking can offer several benefits for warehouses handling large or complex order volumes.

• Hands-free picking
  Employees can use both hands to handle products rather than holding a scanner or paper list. This is particularly useful when picking bulky, awkward or multiple items.
• Fewer picking errors
  The system provides clear instructions for the location, product and quantity, while verbal confirmation helps verify each picking step.
• Faster picking
  Employees receive their next instruction immediately after confirming the previous task. This can reduce unnecessary stops and search time.
• Improved ergonomics
  With no handheld scanner or paper list to operate, employees can concentrate on the physical picking task and maintain a more natural working position.
• Faster employee training
  Voice systems can guide employees through the picking process step by step. Modern systems can also support different languages and individual voice profiles.
• Better process visibility
  As the voice system communicates with the WMS in real time, picking activity can be recorded and monitored as part of the wider warehouse process.

Pick-by-Voice compared with other picking methods

There is no single picking method that is right for every warehouse. The best solution depends on factors such as order volumes, product ranges, warehouse layout and the level of automation required.

Pick-by-Voice is particularly effective where employees process many orders with different routes and need both hands free to pick products.

Introducing voice picking is not simply a case of installing headsets and software. The technology needs to work alongside the warehouse layout, storage systems and existing processes.

Before implementing voice control, consider:

• Which warehouse processes would benefit most from voice guidance?
• Where are delays and errors currently occurring?
• Which areas would benefit from hands-free operation?
• How will the voice system integrate with the WMS and material flow?
• How will employees be introduced and trained on the new system?

A well-planned warehouse layout can make voice picking even more effective. Logical storage locations, short travel distances and ergonomic picking areas can all help reduce unnecessary movement and support a smoother flow of goods.

Pick-by-Voice can be particularly worthwhile when a warehouse:

• Processes a high number of customer orders every day
• Handles a large or varied product range
• Has significant costs associated with picking errors
• Regularly employs seasonal or new warehouse staff
• Needs to improve ergonomic working conditions
• Already operates with a warehouse management system

In these environments, reducing unnecessary movement, interruptions and errors can have a significant impact on the overall picking process.

Yes. Pick-by-Voice can form part of a wider connected warehouse and can be combined with technologies such as:

• Barcode scanning
• RFID
• Pick-by-Light
• Pick-by-Vision
• Automated Guided Vehicles (AGVs)
• Autonomous Mobile Robots (AMRs)
• Conveyor technology

Integrating these technologies can help create more connected material flows and improve visibility across the order-picking process.

Pick-by-Voice can help warehouses create a faster, more hands-free approach to order picking. By connecting employees directly with the warehouse management system, the technology provides clear instructions while allowing them to concentrate on picking.

For warehouses with high order volumes, complex product ranges or demanding fulfilment requirements, voice-guided order picking can be an effective way to improve efficiency, accuracy and ergonomics.

The best results come when the technology is considered alongside the wider warehouse operation — including storage systems, layout, material flow and employee requirements.
