Enabling Differentially Private Federated Learning for Speech Recognition: Benchmarks, Adaptive Optimizers and Gradient Clipping

arXiv — stat.MLThursday, November 27, 2025 at 5:00:00 AM
  • A recent study has established the first benchmark for applying differential privacy in federated learning for automatic speech recognition, addressing challenges associated with training large transformer models. The research highlights the issues of gradient heterogeneity and proposes techniques such as per-layer clipping and layer-wise gradient normalization to improve convergence rates.
  • This development is significant as it provides a practical framework for integrating privacy-preserving techniques in speech recognition systems, which are increasingly vital in applications involving sensitive user data. By enhancing the robustness of federated learning, it opens new avenues for companies like Apple to innovate in privacy-sensitive AI applications.
  • The findings resonate with ongoing discussions in the AI community regarding the balance between model performance and user privacy. As federated learning and differential privacy gain traction, the need for effective optimization strategies becomes critical, particularly in the context of large language models and their applications in various domains, including text-to-speech systems and quantum machine learning.
