Challenge & Requirements

Providing a secured and reliable voice picking system for the supply chain’s multiple activities

As any other industrial field, the supply chain is facing different challenges, may them be human-related or on the technical side of things. Lack of connectivity, data privacy, team onboarding, technology’s resistance to change are some of the obstacles that must be overcome. 

Software reliability and accessibility

Pick-by-voice systems must be used in sometime remote areas that often lack network. On top of the area’s complexities, expected users will have different technological adoptions and must be supported with a large vocabulary tolerance as well as prosody flexibility.

Robust in the use and against data leaks

Reliability comes with the ability to be used in full autonomy but also by securing the company’s data at anytime during the process. Data privacy is a deal-breaker in most industry’s solution if not treated accordingly.

Solution & Specifications

Embedded automatic speech recognition to create a flexible

and reliable pick-by-voice solution

About the speech recognition system itself

The ASR engine is based on a dynamic grammar to understand industry-specific vocabulary as well as multiple word-alternatives per items. The grammar design allows to streamline the voice commands’ vocabulary that on one hand helps with user onboarding with clear and identified instructions and, one the other hand greatly increases the speech recognition’s accuracy.

Focus on end-users' experience

Supply chain companies are always facing human resource turnover and onboarding difficulties. Indeed, the workforce is really heterogeneous in terms of technological adoption and cultural background. This is why the solution must be as permissive as possible to work properly with any profile.

Seamlessly embedded inside voice picking headsets

Speech recognition technology involved in this project is embedded inside mobile devices that are carried by technicians. The technology runs on Android 6.0 (API 23) and above. It doesn’t require specific modification to the device, the native microphone is totally adapted.

Benefits and Improvements

What value does voice AI bring to the supply chain?

Improved speed and productivity

Operators are guided in their different processes with clear and real-time instructions. They can also interact back with the system to share information efficiently, all-in-all working toward speed, accuracy and productivity. 

Enhanced workforce onboarding

Voice-based solutions are so intuitive that anybody can be trained to interact with them properly in a few minutes. This is really convenient in fields like the supply chain in which workforce is always renewing with diverse profiles.

Hands and eyes-free for safety

Most of the supply chain’s activities are in industries, places where safety must be a priority. Thanks to hands and eyes-free capacities, operators using voice-based solution can keep their focus on what they are doing.
