Voice Picking

Voice recognition technologies providing easier communication between the warehouse systems and the picking operator, so they will work hands-free and in greater safety.

Fraunhofer IML validation

In 2023 Onit obtained the Fraunhofer IML validation for On.Plant/WMS.
The important German research institute, part of the largest applied research organization in Europe (Fraunhofer-Gesellschaft), has certified the quality of the software which allows for optimal organization and complete tracking of warehouse flows, from receipt of goods to shipping and returns management.


Voice Picking uses voice engines to communicate with the warehouse operator, who receives the instructions through the headset and confirms the activities carried out via the integrated microphone.

The application allows for fully hands-free work, avoiding errors and increasing safety in the warehouse.

Speech recognition is adaptive, ideal for interpreting the speech of any operator, even in different languages. The headphones ensure clear communication, even in the presence of noise.


  • Increased productivity compared to reading a picking list
  • Fewer errors in the preparation of shipments
  • More safety, being hands-free and not distracted by the display
  • Highly reliable speech recognition thanks to algorithms

Voice Picking features that improve your work

Text-to-Speech TTS

The digital instructions of the company ERP or WMS software are sent to the Voice Picking device which transmits simple and easy to understand audio commands to the operator (e.g. "go to" the picking location, "pick up" number of pieces, "count" location, etc.)

Automatic-Speech-Recognition ASR

The operator replies verbally confirming the operations performed: check-digit to verify that the operator is actually in front of the requested location, quantity of pieces removed, any other commands to request clarifications from the system.

Customizable workflow

Through the interpretation of the commands, the operational flow guides the operator in the execution of the preparations, avoiding errors and facilitating the picking. The decision-making procedure can be customized for preparation specifics (e.g. fine print, variable weight, etc.).


The voice system allows the operator to change the speed of command execution and to enable self-learning of commands to adapt/customize voice interpretation. Different languages can be managed, depending on the operator.

Hardware Independence

The solution is hardware-independent, based on Android or Windows CE OS. The Onit R&D laboratory periodically tests the voice devices and headphones available on the market, in order to certify their interoperability with its systems and their performance.

ERP integration

In addition to being fully integrated with the WMS, the voice-picking module can also be used with external sources, ERP or order portals, which can be easily connected through well-defined and documented standard integrations.
