This repository introduces: 🌀 ShiftySpeech: A Large-Scale Synthetic Speech Dataset with Distribution Shifts
🔥 Key Features
- 3000+ hours of synthetic speech
- Diverse Distribution Shifts: The dataset spans 7 key distribution shifts, including:
- 📖 Reading Style
- 🎙️ Podcast
- 🎥 YouTube
- 🗣️ Languages (Three different languages)
- 🌎 Demographics (including variations in age, accent, and gender)
- Multiple Speech Generation Systems: Includes data synthesized from various TTS models and vocoders.
💡 Why We Built This Dataset
Driven by advances in self-supervised learning for speech, state-of-the-art synthetic speech detectors have achieved low error rates on popular benchmarks such as ASVspoof. However, prior benchmarks do not address the wide range of real-world variability in speech. Are reported error rates realistic in real-world conditions? To assess detector failure modes and robustness under controlled distribution shifts, we introduce ShiftySpeech, a benchmark with more than 3000 hours of synthetic speech from 7 domains, 6 TTS systems, 12 vocoders, and 3 languages.
⚙️ Usage
Ensure that you have soundfile or librosa installed for proper audio decoding:
pip install soundfile librosa
📌 Example: Loading the AISHELL Dataset Vocoded with APNet2
from datasets import load_dataset
dataset = load_dataset("ash56/ShiftySpeech", data_files={"data": f"Vocoders/apnet2/apnet2_aishell_flac.tar.gz"})["data"]
⚠️ Note: It is recommended to load data from a specific folder to avoid unnecessary memory usage.
The source datasets covered by different TTS and Vocoder systems are listed in tts.yaml and vocoders.yaml
