arXiv:2607.03928v1 Announce Type: cross Abstract: Accent normalization (AN) seeks to convert non-native (L2) accented speech into standard (L1) speech while preserving speaker identity. The current techniques either require naturally recorded parallel L1-L2 speech for training, or suffer from quality degradation when supervised by synthesized targets. In this paper, we present TokAN, a token-based accent normalization framework that operates on self-supervised discrete speech tokens extracted from a L1-L2 jointly trained vector-quantization (VQ) tokenizer, without the need of synthetic supervi
Advances in self-supervised learning and vector-quantization tokenizers are enabling more sophisticated speech processing applications without the need for extensive parallel datasets.
This development could significantly improve the accessibility and effectiveness of voice AI technologies for non-native speakers, broadening user bases and reducing friction in global communication.
The reliance on difficult-to-acquire parallel L1-L2 speech data for accent normalization is reduced, allowing for more robust and scalable solutions in speech AI applications.
