tdmelodic: Tokyo Japanese Accent Estimator (PyTorch fork)

Tokyo Dialect MELOdic accent DICtionary (tdmelodic) generator

This module generates a large scale accent dictionary of Japanese (Tokyo dialect) using a neural network based technique.

2026-06: Migrated the neural network backend from Chainer to PyTorch. The public API (Converter.sy2a(), Converter.s2ya()) is fully backward-compatible and produces identical inference results. Now supports Python 3.8+.
