- Introduction
Lingvano was launched in 2020 by a team of Deaf and hearing educators aiming to make ASL accessible worldwide through mobile technology. Its mission is to “empower everyone to communicate with the Deaf community in their own language” by leveraging AI to provide instant feedback on users’ signing . The app is available on iOS and Android, with a web portal for supplemental practice.
- Core Features
2.1 Structured Video Lessons
Lingvano offers over 200 video lessons covering ASL fundamentals—alphabet, numbers, basic phrases—up to advanced grammar and conversational topics . Each lesson includes demonstration videos by native ASL signers, ensuring authentic exposure.
2.2 AI‑Driven Signing Feedback
Using computer‑vision algorithms, Lingvano analyzes users’ handshape, movement, and location to score signing attempts in real time, highlighting errors and suggesting corrections . This immediate feedback loop accelerates motor learning and retention.
2.3 Interactive Quizzes and Games
The app integrates multiple‑choice quizzes, drag‑and‑drop exercises, and “shadowing” games where users imitate on‑screen signers. Progress is tracked via a skill tree, unlocking new modules as mastery is demonstrated .
2.4 Community Forum
Lingvano’s in‑app forum connects learners and Deaf mentors for questions, practice, and cultural exchange. Users can post video practice clips and receive peer or expert feedback .
- Performance and Usability
3.1 Accuracy of AI Feedback
In tests with 50 beginner users, Lingvano’s AI correctly identified signing errors with 92 % accuracy, closely matching evaluations by certified ASL instructors .
3.2 User Interface
The interface features clear navigation, high‑contrast video players, and large touch targets optimized for one‑hand use. Users report the design as “clean and intuitive,” reducing cognitive load during practice .
3.3 Accessibility
Lingvano includes adjustable video playback speeds, closed captions, and voice‑over instructions, making it accessible to users with visual or hearing impairments .
- Content Breadth and Depth
Lingvano’s curriculum spans three learning paths—Beginner, Intermediate, Advanced—with 15 units each . However, some users note that advanced units focus heavily on grammar at the expense of everyday vocabulary, recommending expansion of thematic word lists (e.g., workplace, social settings) .
- Pricing and Subscription
Lingvano operates on a freemium model: free access to the first 10 lessons, then subscription tiers—$9.99/month, $49.99/year, or $99.99 lifetime—for full content . Compared to competitors like The ASL App ($4.99/month) and SignSchool (free), Lingvano’s pricing is mid‑range; users appreciate lifetime access but request family plans or student discounts .
- User Feedback
On Google Play and the App Store, Lingvano holds a 4.6‑star rating from over 2,500 reviews. Users praise the AI feedback, lesson clarity, and supportive community . Criticisms center on occasional AI misreads in complex signs and desire for more cultural notes on Deaf etiquette and history .
- Comparison with Competitors
Lingvano’s unique AI‑driven feedback distinguishes it, though The ASL App offers a larger library of conversational videos .
- Educational Impact
A small study with high‑school students showed that 85 % of Lingvano users improved their receptive and productive signing skills by at least one proficiency level after eight weeks, outperforming peers using static video courses . The immediate corrective feedback was cited as the key differentiator in motor skill acquisition.
