CV-298 (cv_r1): A CC0 Japanese TTS training dataset with per-phone cadence embeddings for prosody pseudonymization

Abstract

[EN] A training-ready dataset for prosody (rhythm) pseudonymization research with Style-Bert-VITS2 JP-Extra, built solely from Mozilla Common Voice Japanese (CC0) , release cv-corpus-25.0-2026-03-09 (ja), validated clips only. Contents: 298 speakers / 18,015 utterances (train 14,226 + eval 3,789), 44.1 kHz mono WAV 7-field transcription lists (esd_train/esd_val) with openjtalk phones, tones, and word2ph Per-mora cadence embeddings ({uid}.wav.cadseq.npy, float32 (n_mora,32), L2-normalized, pauses excluded; 11,010 train utterances covered, remainder uses zeros fallback) Training config (config.json) generated from the public JP-Extra template with explicit overrides only (no proprietary-corpus artifacts involved) MANIFEST.sha256 and a format specification (README_bundle.md) enabling users to build their own datasets in the same format Archives unpack directly into the training root (Data/cv_r1/...) of the companion code repository (branch layer-b-cadence-seq). A Colab deployment/verification notebook is provided in the repository. Known limitation: Common Voice "validated" verifies text correctness only, not speaker identity. A listening-based purity audit identified 9 accounts (of 298) containing voices of multiple people. See the datasheet (docs/DATASET_cv_r1.md in the code repository) for details.
