RedVox

Multilingual red teaming dataset for audio and speech.

This dataset corresponds to the test set presented in the paper "RedVox: Safety and Fairness Gaps in Speech Models Across Languages" (Savoldi, Papi et al., 2026)

Dataset Structure

The dataset is organized by language configuration:

• en/ - English language samples (1,359 entries)
• de/ - German language samples (519 entries)
• es/ - Spanish language samples (354 entries)
• fr/ - French language samples (401 entries)
• it/ - Italian language samples (781 entries)

Total: 3,414 entries

Each directory contains:

• metadata.jsonl - JSONL file with sample metadata and annotations
• audio/ - Directory with audio files in WAV format

Audio Modalities

The dataset includes two main types of input types:

Speech Modality

• Original speech recordings containing hamrful requests uttered by human participants
• Single entry per sample
• audio_type: "speech"

Audio Modality

• Available into 3 audio variants
  • audio_type: "silence" - Background silence
  • audio_type: "noise_a" - Background noise variant A
  • audio_type: "noise_b" - Background noise variant B
