Fleurs-Badini: Translation and Recording Fleurs Dataset for Badini Variant of Northern Kurdish

· Source: Paper Index on ACL Anthology · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Data Science & Analytics · Depth: Expert, medium

Summary

The FLEURS-Badini dataset is introduced as a dialect-focused extension to the multilingual FLEURS speech benchmark, specifically addressing the underrepresentation of Northern Kurdish (Badini). This new dataset, presented at IWSLT 2026, comprises 5,224 utterances paired with translated text, collected from 45 speakers. Its creation involved a structured process of translation, recording, and validation. Baseline experiments conducted with the dataset reveal significant challenges for automatic speech recognition (ASR) and speech-to-text translation (S2TT) in Badini. The W2V-BERT CTC model achieved the best ASR performance with a Word Error Rate (WER) of approximately 55% on the test set. Speech-to-text translation also showed limited performance, yielding BLEU scores of 6.13 on the development set and 5.24 on the test set. FLEURS-Badini aims to provide a standardized foundation for evaluating speech systems in this dialect.

Key takeaway

For NLP Engineers and Research Scientists working on low-resource languages, you should consider the significant performance gaps highlighted by the FLEURS-Badini dataset. Your current ASR and S2TT models will likely struggle with Badini Kurdish, as evidenced by a 55% WER for ASR and low BLEU scores for S2TT. Focus your efforts on developing robust techniques for highly challenging dialects, potentially exploring novel architectures or more effective data augmentation strategies to improve these benchmarks.

Key insights

Badini Kurdish speech data is critical for advancing ASR and S2TT in underrepresented dialects.
