Latest Patents

Yang's latest patents focus on an acoustic echo cancellation (AEC) system and its associated methods. This AEC system includes a loudspeaker interface connected to a loudspeaker, a microphone interface linked to a microphone, and a processor that executes a model. The model is designed to predict and generate a spectral magnitude mask (SMM) through a neural network. This process utilizes a first microphone signal output by the loudspeaker and a second microphone signal output by the microphone. The noisy speech signal is represented as a combination of a clean speech signal and a noise signal. The SMM serves as a ratio of the spectral magnitude of an estimated speech signal to that of the noisy speech signal. Furthermore, a true mask is defined as the ratio of the spectral magnitude of the clean speech signal to that of the noisy speech signal. The model's loss function is calculated as the mean square error between the SMM and the true mask.
