Merlin is an educational 3D low poly mobile game with AI Speech Recognition and ranged combat developed in Unity for Android. Set in a magic castle, you become a young mage apprentice who must read new spells to learn and use them against your enemies in fights.

The main goal was to develop a prototype in which to test the capability of a game with speech recognition to allow kids to learn and practice the ability to read and write, as well as framing the experience more in fun and narrative than creating a purely educational game.

• Switched speech recognition from Microsoft Azure to Vosk for a free, open-source and offline alternative, integrating its API in Unity.

• AI Speech Recognition was used to evaluate if the speech was correct or incorrect, by comparing Speech To Text recognition results to the assigned text.

• UI Programming

• Ranged combat system.

• Scriptable Object Architecture: Levels, Scenes, Assignments & Inventory system for learning spells, as well as for the Dialogue system.

• Tool to update Scriptable Objects (dialogues and spells) from Google Sheets to Scriptable object.

• Added a Karaoke-like effect, highlighting the words that were read and comparing them to the correct phrase for positive and negative feedback on continuous (real-time) speech recognition.

• Built a crafting system (feature ended up being discarded)

• Git / Github for remote team collaboration.
