SEA-SpeechBench: Multitask Benchmark for 11 Southeast Asian Languages

SEA-SpeechBench is a new large-scale benchmark evaluating speech understanding across 11 Southeast Asian languages. Initial evaluations of leading models reveal significant performance gaps, particularly in temporal understanding and low-resource language prompting.

From arXiv cs.CL - “SEA-SpeechBench: A Large-Scale Multitask Benchmark for Speech Understanding Across Southeast Asia”

SEA-SpeechBench is the first large-scale multitask benchmark for speech understanding in 11 Southeast Asian languages. The benchmark contains 97,194 samples across 99 evaluation sets and 597 hours of audio data. It includes nine diverse tasks across three categories: speech processing, paralinguistic analysis, and temporal understanding. Temporal understanding involves timestamped content queries and localization within audio sequences up to 3 minutes. The benchmark utilizes multilingual prompting in native SEA languages and English. Evaluation results show performance gaps across all models, particularly in temporal understanding, emotion recognition, and speech translation. Prompting in low-resource languages such as Burmese and Tamil lags behind English by up to 41 percentage points. This highlights limitations in current models and the need for more inclusive development.

Looped GPT-BERT Achieves Comparable Performance with Fewer Parameters

Researchers demonstrated Looped GPT-BERT, a model utilizing depth-wise parameter sharing and recurrent traversals, achieving performance comparable to larger GPT-2 and GPT-BERT models on benchmarks like BLiMP and GLUE. The design, trained on a 7.48M-word corpus, offers a more efficient approach to language modeling.
