Its paper reports real-time synthesis speed on specified CPU and GPU hardware; those measurements do not imply embedded-device or production suitability.
Kudzika Kwakadzika
MelGAN, introduced by Kumar et al. in 2019, is a non-autoregressive, fully convolutional GAN for conditional waveform synthesis. Its generator upsamples a mel-spectrogram through transposed convolutions, with residual blocks using dilated convolutions. The paper uses multi-scale waveform discriminators and a feature-matching loss to train the generator. It reports qualitative demonstrations in speech synthesis, music-domain translation, and unconditional music synthesis, and uses Mean Opinion Score as a subjective evaluation measure. The authors report that their PyTorch implementation ran at over 100 times real time on a GTX 1080 Ti GPU and over twice real time on CPU without hardware-specific optimizations. These measurements apply to the reported implementation and hardware, not to every deployment or device.
Kuitwa muNyika yeChokwadi
Reproduce the paper’s mel-spectrogram inversion experiment and compare generated waveform quality.
Use the paper’s speech-synthesis and music-domain demonstrations as separate research tasks.
Report mean opinion score when comparing listening quality under the same evaluation conditions.
Measure latency on the target CPU or GPU rather than inferring deployment speed from a different device.
Ramangwana reMelGAN Generative Vocoder
MelGAN provides a research example of non-autoregressive GAN-based waveform synthesis. For a current application, compare audio quality and latency against alternative vocoders on the target data and hardware; the cited paper alone does not establish suitability for mobile, embedded, or streaming deployments.
