HablaYa brings guided lessons, text and voice practice, vocabulary, games, and progress into one responsive learning journey.
Open live productPrivate source
Overview
I designed the learning experience, connected the practice and content systems, built the responsive multilingual interface, and tested releases across the learner journey.
Unified lessons, voice and text practice, vocabulary, games, and progress in one responsive journey.
Context
The operating problem behind the interface.
Learners lose momentum when the lesson, conversation practice, vocabulary, and progress record feel like separate products. The experience needed a clear loop from learning something to using it.
Contribution
From customer signal to a system that can be used and shipped.
What I owned
I designed the learning experience, connected the practice and content systems, built the responsive multilingual interface, and tested releases across the learner journey.
What moved
- 01
I brought lessons, conversations, activities, games, vocabulary, and progress into a shared navigation model.
- 02
I built multilingual, responsive, and installable web-app behavior for practice across devices.
- 03
I added review boundaries around generated course and audio material before it can be treated as finished content.
Key decision
Why this decision
I kept chat and voice interactions in the foreground while secondary work runs without blocking the learner. Practice feels broken if the interface makes someone wait without useful feedback.
What it taught me
Building HablaYa reinforced that a learning product is not a content library. The useful product is the practice loop and the confidence to take the next turn.
Result and current status
Result
The live product gives learners a clearer path from a lesson into practice and back to saved progress, with text and voice available from the same experience.
Current status
HablaYa is a live EdTech product. Its current production repository is private.

Read the visual transcript
The walkthrough starts on a HablaYa learning activity, moves into text and voice practice, and ends with the feedback and progress areas that help the learner choose what to do next. The screens use public example content.
Limitations
- 01
Portfolio media uses public example screens and does not include learner accounts, conversations, or progress records.
- 02
Authenticated chat delivery and real-device microphone quality require separate testing and are not demonstrated by these public captures.
