Ethical and Technical Limits of Deepfake Speech Datasets
TL;DR
Concerns exist regarding the credibility of deepfake speech detectors due to inadequate datasets. A comprehensive audit of 39 deepfake speech datasets was conducted, focusing on attributes like accessibility and demographic coverage.
✦ Why It Matters
Engineers should ensure diverse and well-documented datasets to improve the reliability of deepfake detection systems.
Key Takeaways
- Audit existing deepfake speech datasets for demographic representation.
- Incorporate diverse sources to enhance dataset robustness.
- Document dataset attributes to facilitate transparency.
- Avoid reliance on overlapping datasets to improve evaluation accuracy.
How It Works
The audit methodology involved compiling and analyzing various deepfake speech datasets, focusing on their accessibility, documentation, and demographic coverage. By examining these attributes, the researchers assessed the datasets' suitability for training deepfake speech detection systems.
⚠ The Catch
The lack of demographic metadata in most datasets prevents meaningful fairness assessments, limiting the ability to analyze performance across different demographic groups.
