In some cases, but note that (a) this is only true for a tiny handful of homophones, and (b) the distinguishing accent varies by region.

E.g. "hashi" famously can mean bridge/edge/chopsticks depending on accent, but which accent has which meaning is different in Tokyo vs Osaka.

So shouldn't the better solution be a few more pronounciation markers beyond two strokes, a circle and tiny letters instead of thousands of chinese characters?
