Voice AI tutoring across 14 languages, available 24/7

The challenge

Linguafox wanted to offer conversation practice 24/7 across 14 languages, the single most valuable thing a language learner needs, and the hardest to staff. Hiring native speakers to be available around the clock, for every language, simply wasn't economically or logistically possible.

Without on-demand practice, students hit the classic wall: they learned grammar in class but had nowhere to actually speak between lessons, so confidence and retention stalled.

Human teachers, meanwhile, spent scarce time on repetitive drills instead of the high-value group teaching and motivation only they can provide.

The solution

Voice AI tutors now give every student unlimited speaking practice in their target language, any hour of the day:

• A voice tutor per language, built on the MyChatBot Calls SDK, a Voice Tutor Agent runs for each of the 14 languages, available 24/7 for real spoken conversation.
• Adaptive, personalised lessons, the Lesson Planner Agent uses each student's level and history from the Knowledge Base to adapt difficulty and topics over time.
• Pronunciation correction in the moment, the voice tutor corrects pronunciation during conversation, the practice students can't get from a textbook.
• Available on mobile and web, students practise through the mobile app and web app whenever motivation strikes, not just at lesson time.
• Teachers freed for high-value work, with drills handled by AI, human teachers focus on group classes and motivation, where they matter most.

Linguafox delivered 24/7 conversation practice across 14 languages without hiring an army of night-shift native speakers, and students finally had somewhere to actually speak between lessons.
