# Echo-TTS Robot — DramaBox-annotated (WER=0)

Robot-voice speech generated with **Echo-TTS (EchoDiT preview, `jordand/echo-tts-base`)**
using the **Independent** sampler preset (`cfg_mode=independent`, **CFG=2**,
**speaker KV-scale=2**), conditioned on a robot reference voice. Across the 40
**EmoNet** emotion categories, 5 utterances/emotion (200) were written by Gemini,
each generated with 5 seeds (1000 candidates), transcribed with
**Parakeet-TDT-0.6B-v3**, silence-aware trimmed (500 ms grace, cut in silence),
and only the **WER = 0.00** takes were kept. Kept clips were enhanced with
**RE-USE** (speech enhancement) → **LavaSR** (48 kHz bandwidth extension), then
annotated with **gemini-3-flash** into **DramaBox performance prompts**
(archetype + audible emotions + delivery, exact line in double quotes).

- **101 samples**, all 40 emotion categories represented.
- `robot.tar` — WebDataset (each sample: `<key>.mp3` 160 kbps mono + `<key>.json`).
- `robot/` — the same samples as loose mp3 + json pairs.

Each JSON: `transcription`, `asr` (Parakeet), `dramabox_prompt`,
`perceived_emotions`, `archetype_descriptor`, `emotion`.
