Voice-directed warehousing (VDW) refers to the use of the voice direction and speech recognition software in warehouses and distribution centers. VDW has been in use since the late 1990s

In a voice directed warehouse, workers wear a headset connected to a small wearable computer, similar in size to a Sony Walkman, which tells the worker where to go and what to do using verbal prompts. Workers confirm their tasks by speaking pre-defined commands and reading confirmation codes printed on locations or products throughout the warehouse.

Voice-directed warehousing is typically used instead of paper- or mobile computer-based systems that require workers to read instructions and scan barcodes or key-enter information to confirm their tasks.

VDW increases accuracy,gives secure logon process.
