Our Innovations for Smart Warehousing

Digitalization and automation are widely regarded as the modern solutions to meet the growing demands of production, warehouse, and transport logistics. However, we firmly believe that manual processes will remain a key success factor in the logistics industry. They provide the flexibility and speed required in times of just-in-time delivery and same-day shipping.

Our goal is to further enhance the benefits of manual processes through voice-guided assistance systems, ensuring that employees continue to play a vital role in Smart Warehousing and Logistics 4.0.

The story of LYDIA Voice

From a german systems integrator to a global player

GERMAN PICK-BY-VOICE PIONEERS
The idea for LYDIA is sparked at an international trade fair, marking the beginning of our journey as the first German company to introduce a pick-by-voice system to the market. The first version of topSPEECH-LYDIA is a server-based application on third party hardware. The name “LYDIA” is inspired by one of our team members, Lydia, who lents her voice to record the audio files for the system’s voice outputs.
