+# Makise Kurisu Voice Dataset
+
+A single-character Japanese speech dataset containing 10,469 labeled clips
+(11.055 hours) associated with Makise Kurisu, including the Amadeus Kurisu
+variant. The audio samples were extracted and curated from games and anime in
+the **STEINS;GATE series**.
+
+This is an unofficial, fan-created dataset. It is not affiliated with or
+endorsed by the STEINS;GATE creators, publishers, animation studios, cast, or
+other rights holders.
+
+## Dataset summary
+
+| Property | Value |
+|---|---:|
+| Clips | 10,469 |
+| Duration | 11.055 hours |
+| Language | Japanese |
+| Speaker label | Makise Kurisu |
+| Character variants | Kurisu, Amadeus Kurisu |
+| Audio | WAV, PCM 16-bit, mono, 24 kHz |
+| Train split | 9,299 clips |
+| Validation split | 652 clips |
+| Test split | 518 clips |
+
+### Source media
+
+The samples come from the following STEINS;GATE series source groups:
+
+| Source group | Clips |
+|---|---:|
+| Game — STEINS;GATE (`game:SG`) | 2,831 |
+| Game — STEINS;GATE 0 (`game:SG0`) | 903 |
+| Game — Linear Bounded Phenogram (`game:PHENO`) | 1,737 |
+| Game — STEINS;GATE RE:BOOT (`game:SGRE`) | 2,860 |

+| Anime — STEINS;GATE 0 (`anime:SG0`) | 597 |
+| Anime — Divide By Zero (`anime:SG_DivideByZero`) | 30 |
+
+## Dataset structure
+
+The repository follows the Hugging Face `AudioFolder` layout. Each split keeps
+its audio and `metadata.jsonl` together:
+
+```text
+data/
+├── train/
+│   ├── metadata.jsonl
+│   └── *.wav
+├── validation/
+│   ├── metadata.jsonl
+│   └── *.wav
+└── test/
+    ├── metadata.jsonl
+    └── *.wav
+```
+
+Each metadata row contains:
+
+| Field | Description |
+|---|---|
+| `file_name` | Audio filename, relative to the split directory |
+| `transcription` | Training label; Japanese text with any retained `[gasp]` or `[sigh]` tag |
+| `text` | Japanese transcript without the added expressive tag |
+| `speaker_id` | Normalized speaker ID (`kurisu`) |
+| `speaker_name` | Display label (`Makise Kurisu`) |
+| `character_variant` | `kurisu` or `amadeus` |
+| `source_medium` | `game` or `anime` |
+| `source_series` | Short source identifier |
+| `source_group` | Combined provenance category |
+| `source_quality_tier` | Upstream curation tier (`A`, `B`, or `C`) |
+| `duration_seconds` | Clip duration in seconds |
+| `expressive_tags` | Zero or more retained expressive labels |
+| `from_quarantine` | Whether the source clip came from the upstream short/non-lexical review pool |
+| `sha256` | SHA-256 digest of the published WAV file |
+
+There are 38 `[gasp]` labels and 157 `[sigh]` labels. These bracketed strings
+are dataset conventions, not standardized speech tokens.
+
+## Loading
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("starrydark/Kurisu_Voice")
+print(dataset["train"][0])
+```
+
+For text-to-speech training, use the decoded `audio` feature with
+`transcription`. Use `text` instead if expressive tags are not desired.
+
+## Curation and quality
+
+- Game samples were aligned to their scenario text; anime samples were aligned
+  to Japanese subtitle text and speaker-attributed during upstream curation.
+- Audio was standardized to 24 kHz mono PCM-16 WAV.
+- Source groups were loudness-aligned using one gain value per source group;
+  no per-clip loudness normalization was used.
+- The released split contains only accepted records. A separate 137-item
+  uncertain review pool, build scripts, model outputs, checkpoints, caches,
+  credentials, and local paths are not included.
+- The local pre-publication verifier reported zero failures and zero warnings.
+
+## Intended uses
+
+This dataset may be useful for speech research, Japanese ASR/TTS experiments,
+alignment research, and non-commercial study, subject to applicable law and
+permission from the relevant rights holders.
+
+Do not use it to impersonate the performer, mislead people about authentic or
+official speech, suggest endorsement, harass anyone, or evade copyright,
+publicity, personality, or voice-protection rights. Clearly disclose synthetic
+audio produced from models trained on this dataset.
+
+## Limitations
+
+- The speech is acted character dialogue and is not representative of general
+  conversational Japanese.
+- Anime clips can retain residual music, effects, ambience, or separation
+  artifacts; game clips are generally cleaner.
+- Some speaker attribution and expressive labels were inferred
+  algorithmically and can be incorrect.
+- The source distribution is uneven, and train/validation/test splits are not
+  guaranteed to prevent all scene-level or near-duplicate leakage.
+- The dataset has not received exhaustive human listening review.
+
+## Rights and licensing
+
+The underlying audio, dialogue, characters, names, and STEINS;GATE-related
+marks remain the property of their respective rights holders. No copyright,
+trademark, performer, publicity, personality, or voice rights are transferred
+or licensed by this repository. The repository therefore uses Hugging Face's
+`other` license designation rather than claiming an open-data license.
+
+Users and redistributors are responsible for determining whether their access
+and intended use are lawful and authorized in their jurisdiction. Rights
+holders may contact the repository owner through the Hugging Face repository
+for correction or removal requests.
+
+## Attribution
+
+If you use the dataset in research, cite this dataset page and identify the
+source material as audio from STEINS;GATE series games and anime. This request
+does not replace any attribution or permission required by the rights holders.
