What inspired me?

My love for anime led me to start learning Japanese on Duolingo. At first, I was all in - completing daily lessons and building a solid streak.
But over time, the exercises started feeling repetitive, and eventually my motivation faded along with my streak.
What's interesting though is that I never stopped listening to my Japanese songs playlist on Spotify.

I'd catch myself humming along, trying to mimic words I barely understood and getting excited when I did recognize a word.
I realized — if I could have practiced Japanese by singing my favorite songs, I probably would have kept up with my language learning journey much longer.

How I went about it

RESEarch & Key Insights

Insights from expert interviews with linguists and research for my Masters thesis shed light on the importance of speaking a language and the "moments of delight" it creates between native speakers and learners.

Academic studies indicates that users find activities "too repetitive and over-reliant on receptive skills (listening and reading) as opposed to productive skills (writing and speaking)," with motivation diminishing when users struggle to connect learning to real-world use.

Duolingo has published multiple articles confirming music's effectiveness in language learning, while their handbook emphasizes "building a forever product" and "making it fun" by creating emotionally resonant experiences, making music the perfect medium.

Takeaway

What began as workshop data analysis revealed a broader usability issue, reinforcing the importance of staying open to unexpected insights. This experience has transformed how I approach user research:

  1. I now dedicate time to analyzing secondary patterns in user data, not just the primary metrics
  1. I've incorporated "insight mining" sessions into my research process, where I specifically look for unexpected connections
