How we calculate the even Score

The even Score (0 to 100) sets the order of solutions. It is based only on published reviews:

  • 85% quality: the average of performance, reliability and maintenance effort per review.
  • Recency: newer reviews count more. After one year, a review counts only half as much.
  • Smoothing: with few reviews, the value is pulled towards the category average. A single review cannot push a solution to the very top or bottom.
  • 15% recommendation: how many reviewers would recommend the solution (NPS logic).

None of this can be bought: plans, advertising and partnerships play no part.

„Constructive, goal-oriented, and customer-focused with a short project duration“

In which area do you use the solution, and what problem does it solve for you?

For picking small quantities from fixed locations. Multi-order picking is ideally supported. Hands are free. Article verification using the last 3 digits of the EAN/GTIN. No more picking lists or other paper documents required – saving a great deal of waste and additional recording effort! Direct posting of stock levels and inventory corrections at the storage location just-in-time, with immediate transfer to the WMS.

What is your overall impression of the solution?

Constructive, goal-oriented, and customer-focused. The consulting was excellent, which led to a short project duration.

What specific benefits does the solution offer for your processes, and how do they contribute to improving operations?

The solution is very quick and intuitive to learn. Compared to other vendors, no training for words or numbers is required – you can get started immediately. The system understands everyone well, including employees with German and foreign dialects. In addition, many languages are available. A data package enables the exchange of large amounts of information between the WMS and the Voxter, significantly reducing the number of data transfers and saving time. Thanks to the vest, employees have their hands free, which is a major improvement compared to headsets. Stock levels and inventory corrections can be posted directly at the storage location in real time and transferred to the WMS immediately.

What challenges do you see regarding hardware reliability?

None! The hardware works flawlessly even after years of use. Battery life does decrease over the years, but this is not a disadvantage at all. On the contrary, the battery can be replaced during ongoing operation. The device does NOT need to be shut down and restarted to do so.

What additional features or functions would you like to see in the solution?

I do not wish for any additional features or functions. In logistics, however, a digital, quantity-based verification would be a worthwhile optimization, as this is where the greatest potential for errors exists.

Frequently asked questions

The Pick by Voice solution LYDIA Voice consists of the mobile software component for speech recognition on the mobile device and a server (LYDIA™ Service Hub) for managing the application, devices and users. Speech recognition takes place directly on the mobile end device, ensuring an extremely high recognition speed. LYDIA Voice can be operated either on the robust, voice-optimized VOXTER Voice Terminal or on voice-capable mobile devices from other manufacturers. An industrial-grade headset with a high level of wearing comfort is recommended for voice input and output. Alternatively, the LYDIA VoiceWear picking vest is available as an ergonomic wearing and audio solution that allows completely hands-free operation without a headset. Both variants are designed for continuous use in warehouse environments and ensure reliable communication – even in high-noise conditions. A network connection via Wi-Fi is required to operate LYDIA Voice. LYDIA Voice is connected to the leading warehouse management system (WMS) or ERP system and retrieves the necessary order and master data – such as picking orders, storage locations or item information. In return, the solution sends status messages and confirmations back to the host system in real time. Integration is carried out via proven, standardized interfaces and typically directly, without additional middleware. LYDIA Voice can be operated both on-premises and in cloud environments. Additional applications within the LYDIA Voice Suite ensure maximum user-friendliness, easy support and optimal performance (not all applications are included in the standard package): The LYDIA User & Device Manager consolidates all user, device and voice settings in a central interface, ensuring simple, transparent and secure management of the entire LYDIA Voice environment. LYDIA CoPilot is the integrated support and onboarding tool. It enables key users to accompany employees live, review process quality and analyze speech recognition quality in real time. LYDIA Warehouse Intelligence continuously analyzes all voice and process data from ongoing operations and makes key KPIs transparent – such as recognition accuracy, runtimes, Wi-Fi quality or battery status. Anomalies are detected at an early stage, enabling companies to intervene proactively – including predictive maintenance for devices and processes. LYDIA Phone enables Voice-over-IP calls directly from within the running Pick by Voice application – controlled entirely by voice command. Employees can immediately call the control station when questions or process deviations arise. Connections to active voice clients can also be established from the control station. This saves time, speeds up problem resolution and improves support in day-to-day operations.
