Efficient ASR for Low-Resource Languages: Leveraging Cross-Lingual Unlabeled Data

arXiv — cs.CLTuesday, December 9, 2025 at 5:00:00 AM
  • A systematic investigation into automatic speech recognition (ASR) for low-resource languages has been conducted, focusing on Perso-Arabic languages such as Persian, Arabic, and Urdu. The study demonstrates that leveraging cross-lingual unlabeled data can effectively enhance ASR performance without the need for extensive labeled datasets. A 300M parameter model was developed, achieving results comparable to larger systems while utilizing a 3,000-hour multilingual corpus.
  • This development is significant as it addresses the critical challenge of data scarcity in low-resource languages, enabling better recognition accuracy and accessibility for speakers of Persian, Arabic, and Urdu. By employing innovative techniques such as continual pretraining and morphologically-aware tokenization, the model represents a substantial advancement in ASR technology, potentially transforming communication and technology access in these linguistic communities.
  • The findings resonate with ongoing efforts to improve natural language processing (NLP) capabilities across various languages, particularly those with limited resources. The integration of context-aware strategies in ASR, as seen in recent advancements, highlights a growing recognition of the importance of linguistic diversity and the need for tailored solutions in AI. This trend reflects a broader commitment to inclusivity in technology, addressing the unique challenges posed by dialectal variations and complex grammatical structures in languages like Arabic and Persian.

AraLingBench A Human-Annotated Benchmark for Evaluating Arabic Linguistic Capabilities of Large Language Models
NeutralArtificial Intelligence
AraLingBench has been introduced as a human-annotated benchmark aimed at evaluating the Arabic linguistic capabilities of large language models (LLMs), covering grammar, morphology, spelling, reading comprehension, and syntax through 150 expert-designed questions. The evaluation of 35 Arabic and bilingual LLMs indicates a disparity between high performance on knowledge-based benchmarks and true linguistic understanding, with many models relying on memorization rather than comprehension.
