Towards Personalized Federated Learning for Dysarthric Speech Recognition
TL;DR
Dysarthric speech recognition faces challenges due to speaker variability, complicating the use of standard models. This research introduces personalized federated learning techniques, specifically parameter-based and embedding-based averaging strategies, to enhance recognition accuracy.
✦ Why It Matters
Engineers can leverage personalized federated learning to improve speech recognition systems for diverse user populations.
Key Takeaways
- Explore personalized federated learning for diverse speech recognition applications.
- Implement parameter-based and embedding-based averaging strategies.
- Evaluate performance improvements using UASpeech and TORGO datasets.
- Focus on reducing word error rates for better user experience.
How It Works
The proposed personalized federated learning methods address speaker variability by allowing individual models to adapt based on personal speech characteristics. Parameter-based averaging combines model parameters from different users, while embedding-based averaging focuses on merging user-specific speech embeddings, leading to improved recognition accuracy.
