Research Directions
- Beamforming (BF) refers to the use of a microphone array to achieve directional processing, allowing signals within the main lobe to pass through without loss, while effectively suppressing signals in the side lobes.
- By controlling the sound field in bright and dark zones, different spatial allocations of the sound field can be achieved.
- Source separation (SS) is synonymous with the cocktail party problem, referring to the extraction of individual speakers from mixed signals of multiple speakers.
- The objective of AED is to identify and classify different types of sounds present within an audio signal.
- Sound quality restoration includes various aspects such as noise reduction, Howling suppression, and speech super-resolution, aiming to enhance overall audio quality.
- The rapid development of large models has provided many possibilities for downstream tasks using LLM.
- When electric vehicles travel at low speeds in pure electric mode, their low noise levels make it difficult for pedestrians to detect their approach, leading to potential traffic accidents. Therefore, electric vehicles should emit sound proactively at low speeds to alert pedestrians.
- Utilizing a transformer-based encoder-decoder architecture, easy transcription can be achieved.
- Active Noise Control (ANC) utilizes the principle of phase inversion to actively cancel noise, creating a quiet environment.
- Acoustic Echo Cancellation (AEC) uses the far-end signal as a reference to eliminate echoes in the near-end signal, ensuring clear communication.
