We tested each app for a minimum of four weeks, recording the same target phrases weekly to measure whether feedback translated to actual improvement. Evaluation dimensions: feedback granularity (phoneme-level vs. word-level vs. pass/fail), speech model quality across multiple L1 backgrounds, whether coaching felt calibrated to individual patterns or generic, and long-term improvement as measured by blind comparison of week-one vs. week-four recordings by a native speaker.

We weighted feedback granularity and calibration heavily because the central question for a pronunciation app isn't whether it can hear you — speech recognition is commoditized — but whether it can tell you what to fix and why.
