New diffusion model offers controllable accent normalization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed DLM-AN, a novel system for controllable accent normalization that utilizes masked discrete diffusion over self-supervised speech tokens. This method allows for tunable accent strength by selectively reusing source tokens, enabling applications like language learning and dubbing to retain or reduce accents as needed. The system also incorporates a duration ratio predictor to match native speech rhythms and has demonstrated superior performance in reducing word error rates while offering smooth accent control. AI

IMPACT This research could enable more nuanced speech synthesis and analysis tools for applications like language learning and content localization.

    Controllable Accent Normalization via Discrete Diffusion

    arXiv:2603.14275v3 Announce Type: replace-cross Abstract: Existing accent normalization methods do not typically offer control over accent strength, yet many applications-such as language learning and dubbing-require tunable accent retention. We propose DLM-AN, a controllable acc…
