Language Learning Assistant Enhanced by AI
A voice-enabled AI teacher, developed by the SapientPro team, brings real-time language learning to life through interactive avatars, adapting to skill levels, correcting in the moment, and simulating the experience of a live tutor.
Our Collaboration Story
In December 2024, the client turned to SapientPro to bring their concept to life. Together, we set out to build an intuitive, instructor-focused platform for language learning. While it launched with Dutch, the system was designed from the start to support multiple languages. The key goal was to give students real choice in how they learn and who they learn with. By March 2025, we delivered a fully functional solution developed in step with the school’s curriculum and teaching approach.
Teachers now work more productively with pre-built lesson templates, real-time attendance tracking, and an interactive whiteboard that integrates audio, video, and built-in pronunciation insights. Students experience language learning on their own terms: short, dynamic lessons in the language they choose, instant feedback on pronunciation, easy homework submission, and the ability to switch teachers anytime. This has created a dynamic learning space – flexible, interactive, and built for both teachers and students
Challenges
Responsive Voice Interaction
To support real-time speaking practice, the platform needed to process voice input, generate a response, and deliver spoken output, all within milliseconds, without breaking the natural flow of conversation.
Realistic, Engaging Avatars
Creating a digital avatar that felt natural in live dialogue meant combining speech output with expressive facial animation and fluid timing.
Supporting Active Conversations Across Users
The platform had to support multiple learners interacting with avatars simultaneously, without lag or performance dips.
Meaningful In-the-Moment Feedback
Students needed grammar and pronunciation guidance without disrupting conversation. Feedback had to be immediate and contextual, not post-session.
Interactive Learning: Key Features for Language Learners
Vocabulary Support Within Sessions
Any word can be selected for additional support, including definitions, contextual examples, and short reinforcement exercises.
Adaptive Learning Paths
Content difficulty and focus areas automatically adjust based on the learner’s ongoing performance and progress.
