■ Daily Challenge & Streak
Sharpen your speaking with Today's Challenge. Custom sentences are prepared each day based on your weak phonemes. Keep showing up and build your streak.
■ AI Pattern Diagnosis (Phoneme Level)
PixelSpeech studies your accumulated results and automatically detects the pronunciation patterns you repeatedly struggle with:
- Final consonant (batchim) weakness
- Aspirated consonants (k/t/p/ch)
- Tense consonants (kk/tt/pp/ss/jj)
- The Korean R/L sound
- Complex vowels
- Diphthong glide loss
- Vowel accuracy
Once enough data is gathered, it surfaces your three weakest patterns so you know exactly what to practice first.

The slower version of every word seems like normal speed and the normal speed is very fast I wish the slow version was actually slow and the ai voice is very hard to understand but for words I already know this app is very helpful on how to pronounce them wellI also wish I could search up a word and pronounce it if I’m trying to improve my pronunciation for a certain word
Developer Response
Update — all three are now live! 🎉• Playback speed: fixed. "Slow" is genuinely slower and the default sounds natural.• Search a word: just type any Korean word or sentence on the home screen to hear it and practice — now much easier to find.• Clearer AI voice: we switched to a natural neural voice, so words are far easier to understand.Your feedback directly shaped these updates — thank you. Please grab the latest version and let us know what you think! 🎤
New: a weekly plan, unlockable tracks and a one-month report. Every Monday a 3-step plan opens (weak sounds, track sentences, re-check). On Day 7 and Day 14, part 2 of the K-drama, travel, business and TOPIK tracks unlock in turn. On Day 30 you get a one-card summary of your checks, score change and graduated sounds. Also fixed game errors on some devices.
