Today’s session was supposed to be simple: review what I learned yesterday, pick up one or two new phrases, get in my 20–30 minutes, and call it a win. Instead, I learned something unexpected—not all AI real-time voice modes are created equal.
Trying Claude’s Voice Mode (And Why It Fell Apart)
I started with Claude’s live voice feature, and within minutes it felt like stepping back into the era of Voxer—those old walkie-talkie apps where you had to hold a button just to talk. Claude works the same way:
- Tap to talk. Stop. Listen. Tap again.
- No natural back-and-forth.
- Constant wondering: Did it catch what I said? Is it waiting for me? Am I waiting for it?
That alone broke the flow. But then came the bigger issue: Korean speech detection was awful.
I’d say something as basic as 안녕하세요 and watch it just… fail to register. I moved the phone. I repeated it. Slower. Faster. Clearer. Still nothing.
It felt like a substitute teacher who walked into the room, shrugged, and said: “Uh… yeah, just read these worksheets to yourself. I don’t actually know Korean.”
And the pronunciation on its end? Even with my four days of Korean, I could tell something was off. Everything sounded like a British guy confidently mispronouncing every syllable.
At that point the experiment was basically over.
Back to Gemini—Like Returning to a Real Teacher
After ten minutes of fighting with Claude, I switched to Gemini, and the difference was immediate:
- It detected my Korean.
- It pronounced the Korean correctly.
- It remembered my notes from yesterday and scaffolded today’s lesson on top of them.
Gemini taught me:
- 좋아해요 = “I like…”
- 커피를 좋아해요. (I like coffee.)
- 안 좋아해요 = “I don’t like…”
- 저는 한국어를 안 좋아해요. (I don’t like Korean.)
- Reinforced earlier material without feeling repetitive.
It felt like a teacher who understood the last class, knew where to push, and didn’t waste time.
Final Thoughts for Day 4
Today wasn’t a glamorous study day, but it was a useful one.
- Claude’s voice mode: not ready for Korean practice.
- Gemini: still the best at teaching, detecting, and scaffolding Korean in real time.
- Me: still here, still showing up for Day 4, still learning.
I kept the video short, but if you want to see the actual footage—the failed Claude attempts and the smoother Gemini session—you can check it out below.
On to Day 5.
