END-TO-END MULTI-TASK DENOISING FOR JOINT SIGNAL DISTORTION RATIO SDR AND PERCEPTUAL EVALUATION OF SPEECH QUALITY PESQ OPTIMIZATION

摘要

Methods and systems for providing end-to-end multi-task noise denoising for optimizing joint signal distortion ratio (SDR) and perceptual evaluation of speech quality (PESQ) Is disclosed. According to one embodiment, the method receives a noisy signal, generates a denoised output signal, and determines an SDR loss function based on the noise-eliminated output signal, Determining a PESQ loss function based on the noise canceled output signal, and optimizing the overall loss function based on the PESQ loss function and the SDR loss function.
