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.

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

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:

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

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.
