During a DCW (Distribution Center Walkthrough) by DatAction and partner Art4L, we noticed a number of shortcomings in Paccar Parts’ existing voice system. After an extensive analysis of the logs, we came to the conclusion that there was not only a need for a software revision, but also for an optimization of the voice recognition and simplification of the picking prompts.

The new application was equipped with adaptive recognition technology. This technology reduces the chance of recognition errors. Based on the expected voting input from the user, the voting templates are intelligently adjusted automatically.

The picking task was better aligned with picking in practice, so that the entire process runs smoothly and without errors. Furthermore, by fine-tuning the recognition parameters, we prevent the system from incorrectly recognizing commands (so-called substitutions / insertions).

In terms of hardware, the oldest Honeywell TalkMans (voice devices) were replaced by the new Honeywell TalkMan A720X with SRX-3 wireless headsets. These headsets optimally suppress ambient noise. The voice task is now compatible with both the new (Linux) devices and the existing (CE) TalkMans. This allowed the old devices to be replaced without interrupting warehouse activities. An additional investment for DAF was not necessary because we kept the same interface with the mainframe.

The adapted voice application was first extensively tested in Eindhoven, whereby the old and the new application could be used simultaneously during the transition phase. The roll-out to foreign branches will start in the coming weeks.
