Could you build this?
Partial Orchestrating text-to-speech with canvas animations is accessible, but precise frame-by-frame vector stroke synthesis aligned with audio phonemes requires custom graphics algorithms.
What it would actually take: Implemented via Node.js/Python using Remotion, FFmpeg, and vector graphics parsing (such as Rough.js or custom SVG path interpolation). The difficult part is the timing engine that maps forced-alignment audio timestamps to stroke-by-stroke path drawing and handwritten Chinese character stroke order databases.
