# Model Card for VoXtream2 Seamless test dataset

This repository contains a test dataset for the [VoXtream2](https://huggingface.co/voxtream2/model) TTS model, referred to as **Seamless test** in the paper.

Audio files are derived from the [Seamless Interaction](https://huggingface.co/datasets/facebook/seamless-interaction) dataset.
We build a test set from the naturalistic subset of the Seamless Interaction test split.
We select 10-20-second sentences whose average speaking rates are uniformly distributed over 2-6 SPS, from 45% male and 55% female speakers.
For each speaker, the 3-7-second acoustic prompt (4.7 seconds on average) is taken from another sentence with an average rate of 3-4 SPS.
After removing sentences with a Whisper-large-v3 WER above 10%, we sample 322 unique sentences, totaling 1.1 hours.

* Note: SPS - syllables per second, WER - word error rate

### Description

- **prompt-audio** - Audio prompts from Seamless interaction dataset (24kHz, flac format).
- **audio** - Audio files from Seamless interaction dataset (24kHz, flac format).
- **metadata.csv** - Test protocol for **Seamless test**, listing audio prompts and corresponding sentences to generate.

## Usage

To download the dataset, use the following code:

```bash
from huggingface_hub import snapshot_download
local_dir = snapshot_download('voxtream2/seamless', repo_type='dataset')
```
