HiFi-SR: A Unified Generative Transformer-Convolutional Adversarial Network for High-Fidelity Speech Super-Resolution
HiFi-SR is a single end-to-end transformer-convolutional GAN that upscales speech from 4 to 32 kHz inputs to 48 kHz with slightly better spectral distance and listener preference than existing two-stage systems.
