Unofficial Parallel WaveGAN Demo

Description

This platform serves as an unofficial demonstration hub for advanced audio synthesis models, primarily focusing on Parallel WaveGAN and its related architectures. It provides a direct comparison of audio samples generated by different implementations, allowing users to evaluate their quality and characteristics.

The demo features several prominent models, including Parallel WaveGAN (both official and an unofficial implementation), MelGAN, Multiband-MelGAN, HiFi-GAN, and StyleMelGAN. These models are showcased with audio samples generated from distinct datasets and languages, offering a comprehensive overview of their capabilities.

For English audio, the demonstration utilizes the LJSpeech dataset. Users can compare the ground truth speech against outputs from the official Parallel WaveGAN, the unofficial implementation, and other models like MelGAN with STFT-loss, FB-MelGAN, MB-MelGAN, HiFi-GAN, and StyleMelGAN. A key technical detail highlighted is the limitation of the Mel spectrogram calculation to a frequency range of 80 to 7600 Hz.

Similar demonstrations are provided for Japanese and Mandarin languages. The Japanese samples are trained on the JSUT dataset, with ground truth audio at 48 kHz being downsampled to 24 kHz for comparison, also with a Mel spectrogram frequency range limited to 80-7600 Hz. The Mandarin samples are derived from the CSMSC dataset, following the same downsampling and frequency range limitations.

This resource is invaluable for researchers, developers, and audio engineers interested in the latest advancements in neural vocoders and speech synthesis. By providing direct audio comparisons and links to the underlying GitHub repositories, it facilitates further exploration and development in the field of AI-driven audio generation.
