The paper introduces ABX-Accent, a benchmark built on the AESRC dataset that evaluates how well representation learning models adapt to 10 different English accents with less than 10 hours of unlabeled data per accent. It adapts the Zero Resources Challenge ABX metrics for each accent and demonstrates a baseline using adaptive domain normalization to fine‑tune a Contrastive Predictive Coding model, achieving a 23.6% relative improvement on across‑speaker ABX scores compared to non‑adapted models. The dataset and evaluation metrics will be released publicly after the paper is accepted.

The paper evaluates the robustness of DistilHuBERT for accent classification using speaker‑disjoint splits and cross‑corpus tests with L2‑ARCTIC and other English accent datasets. It finds a large performance gap between in‑corpus and external evaluations, indicating that file‑level tests overestimate accuracy. The study shows that balanced external‑data training performs best, while pseudo‑labeling with confidence filtering is insufficient under domain mismatch.

Recent advances in zero-shot text-to-speech (TTS) have substantially improved speech quality and voice cloning fidelity. However, many zero-shot TTS systems still depend on audio prompt transcripts at inference time.
