arXiv:2606.19910v1 Announce Type: new Abstract: Training automated pronunciation assessment often relies on labeled learner errors or non-native corpora that are costly to collect. We propose a lightweight framework trained only on native speech resources, operating unsupervised or lightly calibrated with a small set of scored utterances. At inference, learner speech is discretized with an SSL encoder and a K-means codebook. A token language model trained on native sequences computes surprisal where higher surprisal indicates phonotactic deviation. We add a transcript-guided Text2DUnit--DTW mo
The increasing demand for practical and scalable AI applications, coupled with advancements in self-supervised learning, makes efficient pronunciation assessment a timely development.
This development offers a resource-efficient method for AI-driven language education and assessment, reducing dependency on costly, human-labeled data and expanding accessibility.
The ability to train pronunciation assessment tools on native speech alone significantly lowers the barrier to entry for developing and deploying such systems, especially for less-resourced languages.

More accurate and accessible automated pronunciation assessment tools become widely available.
This could lead to a proliferation of AI-driven language tutoring and assessment services, enhancing global language education.
Improved, low-cost pronunciation feedback might accelerate conversational AI development by creating better synthetic speech and understanding of non-native accents.
