# CommonVoice ITTS Controllability Validation Set

Ground-truth-labelled English speech clips drawn from
[`fixie-ai/common_voice_17_0`](https://huggingface.co/datasets/fixie-ai/common_voice_17_0)
(Common Voice 17.0, CC0), used to validate audio-LM **judges** for
instructable-TTS (ITTS) controllability scoring on **age**, **gender**, and
**native accent**.

Each clip carries a human-provided attribute label from Common Voice, so a judge's
perceived-attribute accuracy can be measured against real ground truth (blind
perceived-accuracy protocol).

## Contents

- `data/*.mp3` — 198 source clips (~108 MB).
- `metadata.jsonl` — 271 rows, one per (clip, attribute).

Cells (30 per value unless noted):

| attribute      | values                                              |
|----------------|-----------------------------------------------------|
| age            | young_adult, middle_aged, elderly                   |
| gender         | female, male, non_binary (1)                        |
| native_accent  | american, australian, british, indian              |

Age bands: young_adult 13–39 / middle_aged 40–59 / elderly 60+.

## Fields

- `file_name` — relative path to the audio (AudioFolder convention).
- `id` — `<clip>-<attribute>`.
- `attribute` — one of `age` / `gender` / `native_accent`.
- `requested_label` — ground-truth Common Voice label for that attribute.
- `text` — reference transcript.
- `language` — `en`.
- `source` — `common_voice_17_0`.

A clip may appear under more than one attribute (same speaker labelled for age,
gender, and accent).

## Usage

```python
from datasets import load_dataset
ds = load_dataset("audiofolder", data_dir="<local_dir>", split="train")
```
