**KVoiceBench** is a Korean spoken question answering benchmark for evaluating speech models, built upon [VoiceBench](https://arxiv.org/abs/2410.17196). ## Dataset Description As there is no existing benchmark for evaluating Korean spoken question answering capabilities, we construct KVoiceBench by building upon the English benchmark VoiceBench. **Construction process:** 1. All transcriptions from VoiceBench are translated into Korean. 2. Translations are normalized into speech-friendly text. 3. Audio is synthesized using a Qwen3-TTS system. 4. Linguistic features that do not exist in Korean (e.g., capitalization, certain grammatical rules) are removed or adapted to better align with the Korean language. ## Subsets The dataset consists of **6,928** samples across 9 subsets: | Subset | Samples | Task Type | |---|---|---| | OpenBookQA | 445 | Multiple-choice QA | | MMSU | 3,006 | Multiple-choice QA | | Big-Bench-Hard | 750 | Multiple-choice QA | | SD-QA | 533 | Short-answer QA | | AlpacaEval | 614 | Open-ended | | CommonEval | 194 | Open-ended | | WildVoice | 972 | Open-ended | | IFEval | 279 | Instruction following | | AdvBench | 513 | Safety | ## Features - **id** (string): Unique sample identifier - **audio** (Audio): Synthesized Korean speech audio - **transcription** (string): Korean text transcription of the audio - **answer** (string): Reference answer (empty string for open-ended/safety subsets) - **capability** (string): Evaluated capability category ## Usage ```python from datasets import load_dataset # Load a specific subset ds = load_dataset("KRAFTON/KVoiceBench", "bbh-test", split="test") print(ds[0]) # {'id': 'bbh_navigate_147', 'audio': {'path': ..., 'array': array([...]), 'sampling_rate': 24000}, # 'transcription': '...', 'answer': '...', 'capability': 'context_related/multi_hop_reasoning'} # Load all subsets subsets = [ "advbench-test", "alpacaeval_full-test", "bbh-test", "commoneval-test", "ifeval-test", "mmsu", "openbookqa-test", "sd-qa", "wildvoice-test" ] for subset in subsets: ds = load_dataset("KRAFTON/KVoiceBench", subset, split="test") print(f"{subset}: {len(ds)} samples") ``` ## Citation ```bibtex @article{kvoicebench2026, title={KVoiceBench: A Korean Spoken Question Answering Benchmark}, author={}, year={2026} } ``` ## License This dataset is released under the [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0). © 2026 KRAFTON
