# DLM-AN: Controllable Accent Normalization via Discrete Diffusion

This repository contains the pretrained checkpoints for **DLM-AN**, the inference release for the paper [*Controllable Accent Normalization via Discrete Diffusion*](https://huggingface.co/papers/2603.14275) (Interspeech 2026).

**DLM-AN** (Diffusion Language Model for Accent Normalization) is a controllable accent normalization system built on masked discrete diffusion over self-supervised speech tokens. It provides tunable accent strength through a Common Token Predictor that selectively reuses source tokens, and includes a flow-matching Duration Ratio Predictor to better match native rhythm.
