About the project
For RZD, we developed an educational platform where employees could study learning topics and take knowledge assessments with an AI assistant via voice interaction. The project was conceived as a more modern alternative to conventional tests and formal training. Instead of a static scenario with answer choices, the user interacted with the system in a conversational format: studying material, answering questions by voice, and receiving real-time feedback throughout.
The Challenge
We needed to create a digital tool for studying regulatory documentation and conducting knowledge assessments in a more convenient and natural format. For the client, this meant making learning more interactive and assessment more aligned with real communication — where the goal is not simply to select the correct answer, but to demonstrate understanding of the topic and the ability to reason through it.
Our Solution
- Built a web service combining an educational platform with a voice AI assistant
- Implemented speech recognition pipeline using VOSK and Yandex SpeechKit
- Integrated LLM-based response analysis to evaluate answer content and quality
- Built conversational logic: follow-up questions, context retention, and scenario progression
- Developed assessment logic to evaluate not just factual correctness but depth of understanding
Results
- Working voice AI training service delivered in 2 months
- Learning became more interactive — users engage in dialogue rather than selecting from fixed options
- Assessment format moved closer to real communication, testing understanding rather than recall alone
- Regulatory knowledge checks can now be conducted in a flexible, conversational digital format
