# skycmd ear questions (s6-ear)

The audio questions of s6-ear (turn end, keyword spotting, zero-shot keywords), the index of every clip and the Mimi codes of its audio pretraining.

Part of [skycmd](https://github.com/maxgfr/skycmd), tiny decision models trained from scratch in Rust that run in the
browser. Written by `sky-data fetch-audio and sky-data audio-jev` at commit [`84c6d854`](https://github.com/maxgfr/skycmd/commit/84c6d854cdc2a9f6d951ebb55780060a01f38ca6).
Licences of every set: [DATA_LICENSES.md](https://github.com/maxgfr/skycmd/blob/main/DATA_LICENSES.md).

- the question configs (`turn_end`, `keyword`, `keyword_zs`) have the typed-decision schema of
  skycmd-decisions (`src`, `t`, `ins`, `opts`, `state`, `target`, `split`) plus `lang` and `clip`;
  `state` is the path of the clip's float16 log-mel features (`.npy`) relative to the question file;
- the `clips_*` configs index every clip: `id`, `set`, `split`, `lang`, `mel` (features path),
  `frames`, `label`, and `wav` for the test clips;
- the `mimi_*` configs give, per LibriSpeech utterance, its features path and its Mimi codes.

**The audio is not in this repository** (31 GB of log-mel features and 16 kHz test WAVs): it is
rebuilt from the upstream sets by `sky-data fetch-audio`, deterministically, with the same paths.

## Sources and licences

Each config is one source and keeps **its source's licence** (share-alike sources stay share-alike).
Attribution goes to the upstream authors; the conversion is ours.

skycmd wrote no row with a language model: the targets come from the upstream labels (some upstream
sets carry their own teacher soft labels, see their cards), the games' oracles or our generators.
