Visual Pronunciation Feedback With Waveform Annotation And Error Highlighting

Unique: Combines waveform and spectrogram visualizations with phoneme-level error highlighting, enabling users to see both the temporal and frequency characteristics of mispronunciations. Likely uses a web-based audio visualization library (e.g., Wavesurfer.js) with custom phoneme annotation overlays.

vs others: Provides visual feedback that text-based feedback alone cannot convey, helping learners understand the acoustic basis of their errors and enabling self-correction through pattern recognition
