🎙 ASR Showdown: Clova Note vs. Daglo in Korean— Which One Really Listens?

Capturing the real voice of the user is only half the battle. The other half is getting an automatic-speech-recognition (ASR) system that won’t leave you cleaning up a transcription disaster just when the analysis clock starts ticking. We put two of Korea’s most popular ASR tools head-to-head so you don’t have to.

🔍 Evaluation Criteria

  1. Context integrity – Does the conversation flow naturally?

  2. Sentence completeness – Are utterances grouped into full sentences?

  3. Noise & typos – How many split fragments or obvious errors?

  4. Analysis readiness – How easy is speaker or topic tagging?

Why it matters: Each extra fragment means one more manual merge or deletion before you can even start coding the data.

🧠 What the Numbers Mean

  • Daglo nails micro-level timestamps, but its aggressive splitting chops a continuous discussion into hundreds of tiny fragments. Analysts lose context and burn time re-stitching sentences.

  • Clova Note keeps utterances bundled into coherent blocks. For long FGDs and 1-on-1 interviews, that translates into hours saved on clean-up and faster passage to thematic coding.


✅ Bottom Line

Clova Note is the safer bet when context and post-processing time matter.

Accuracy is only the first filter. In real-world UX research, a transcription tool must also preserve narrative structure and minimize analyst effort. On those two fronts, Clova pulls ahead.
