Abstract
An audio denoising system includes an edge device and a server device. The edge device executes a local audio denoising model to process input audio signals. The server device receives audio samples from the edge device, detects audio events, identifies background noise segments, fine-tunes a corresponding server-side model using the noise segments, and transmits fine-tuned parameters to update the local model, thereby enhancing denoising performance in dynamic environments.

An audio denoising system, comprising:
- an edge device, comprising:
- a microphone, configured to acquire an audio sample from an environment;
- a memory, storing a local instance of an audio denoising model;
- and
- a processor, configured to execute the local instance of the audio denoising model to denoise an input audio signal;
- and
- a server device, configured to:
- receive the audio sample from the edge device;
- detect, from the audio sample, one or more audio events corresponding to a plurality of audio event categories;
- identify background noise segments in the audio sample based on the detected audio events;
- fine-tune a server-side instance of the audio denoising model corresponding to the local instance using the identified background noise segments to obtain fine-tuned model parameters;
- and
- transmit the fine-tuned model parameters to the edge device;
- wherein the processor is further configured to update the local instance of the audio denoising model using the fine-tuned model parameters.
A method for fine-tuning an audio denoising model, executed by a server device, the method comprising:
- receiving an audio sample from an edge device, wherein the audio sample is acquired by the edge device using a microphone;
- detecting one or more audio events from the audio sample corresponding to a plurality of audio event categories;
- identifying background noise segments in the audio sample based on the detected audio events;
- fine-tuning a server-side instance of the audio denoising model using the identified background noise segments, thereby obtaining fine-tuned model parameters;
- and
- transmitting the fine-tuned model parameters to the edge device;
- wherein the fine-tuned model parameters are used by the edge device to update a local instance of the audio denoising model corresponding to the server-side instance, and the local instance of the audio denoising model is executed by the edge device to denoise an input audio signal.
