WildDESED: An LLM-Powered Dataset for Wild Domestic Environment Sound Event Detection

Welcome to the WildDESED dataset repository! This dataset is designed to advance research in sound event detection (SED) within the challenging and diverse acoustic environments of domestic settings.

Overview

WildDESED is an extension of the original DESED dataset, created to reflect a wider variety of domestic scenarios by incorporating complex and unpredictable background noises. These enhancements make WildDESED a powerful resource for developing and evaluating noise-robust SED systems.

Key Features

• Diverse Scenarios: The dataset includes eight domestic scenarios such as "Morning Routine" and "Home Office," designed using large language models (LLMs) to ensure realism.
• Rich Acoustic Variety: Background noises include bird chirping, car passing by, fan noise, and many more, integrated to simulate real-life domestic environments.

Dataset Structure

The WildDESED dataset is organized into the following subsets same as the original DESED dataset:

1. Synth Training Set: 10,000 synthetic recordings with strong annotations.
2. Synth Validation Set: 2,500 synthetic recordings for model validation.
3. Weak Set: 1,578 real recordings with weak annotations.
4. Unlabeled Training Set: 14,412 real, unlabeled recordings.
5. Test Set: 1,168 real recordings with strong annotations.

Noise Types and Scenarios

The dataset includes a variety of noise types categorized into four groups based on their acoustic characteristics:

1. Ambient Environmental Sounds: Continuous background noises like light rain and wind blowing.
2. Human-Related Sounds: Sporadic sounds such as footsteps and door closing.
3. Mechanical Sounds: Noises like clock ticking and coffee machine operation.
4. Nature and Outdoor Sounds: External noises including bird chirping and car passing by.

Each scenario combines these noises with target sound classes from the DESED dataset, ensuring that the resulting soundscapes are both realistic and challenging for SED systems.

Scenario Examples
