- **Total Duration**: ~8 hours (the editing version includes less)
- **Format**: LJ Speech-style format (wav files and corresponding text)

- **Text Correction**: Efforts were made to correct transcripts of mispronounced words while preserving as much data as possible. However, **no guarantees are made regarding grammatical or spelling accuracy**.

- `Cyril/` – Edited recordings of Cyril in LJ Speech format
