Towards Lightweight Adaptation of Speech Enhancement Models in Real-World Environments
This paper introduces a lightweight, self-supervised adaptation framework for Speech Enhancement (SE) models in dynamic real-world acoustic environments. It addresses the computational and memory costs of existing adaptation methods, making it suitable for on-device deployment. The framework leverages low-rank adapters, updating less than 1% of the base model's parameters, and demonstrates significant SI-SDR improvements (average 1.51 dB) within 20 adaptation steps. This approach ensures robust SE performance under continually evolving acoustic conditions.

Update Low-Rank Adapters
| Method | Parameters Updated (%) | SI-SDR Improvement (dB) |
|---|---|---|
| RemixIT | 100% | 1.17 dB (sequential) |
| Our Method | <1% | 1.51 dB (sequential) |
The proposed framework achieves superior or comparable performance to state-of-the-art methods like RemixIT, while drastically reducing the number of updated parameters. This highlights its efficiency without compromising quality.
On-Device Deployment Feasibility
The proposed framework significantly reduces the computational and memory footprint, making it highly suitable for on-device deployment. By updating only a small fraction of parameters, it overcomes the limitations of prior methods, enabling robust speech enhancement in edge devices with limited resources. This is crucial for applications like hearing aids and smart assistants in dynamic, real-world acoustic conditions.
