Audio Spotforming Using Nonnegative Tensor Factorization with Attractor-Based Regularization

Shoma Ayano, Li Li, Shogo Seki +1

Spotforming is a target-speaker extraction technique that uses multiple microphone arrays. This method applies beamforming (BF) to each microphone array, and the common components…

Improved Remixing Process for Domain Adaptation-Based Speech Enhancement by Mitigating Data Imbalance in Signal-to-Noise Ratio

Li Li, Shogo Seki

RemixIT and Remixed2Remixed are domain adaptation-based speech enhancement (DASE) methods that use a teacher model trained in full supervision to generate pseudo-paired data by rem…

Remixed2Remixed: Domain adaptation for speech enhancement by Noise2Noise learning with Remixing

Li Li, Shogo Seki

This paper proposes Remixed2Remixed, a domain adaptation method for speech enhancement, which adopts Noise2Noise (N2N) learning to adapt models trained on artificially generated (o…

Wave-U-Net Discriminator: Fast and Lightweight Discriminator for Generative Adversarial Network-Based Speech Synthesis

Takuhiro Kaneko, Hirokazu Kameoka, Kou Tanaka +1

In speech synthesis, a generative adversarial network (GAN), training a generator (speech synthesizer) and a discriminator in a min-max game, is widely used to improve speech quali…
