|
|
| **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") |
| ``` |
