Query: WaveCycleGAN2: Time-domain Neural Post-filter for Speech Waveform
  Generation   WaveCycleGAN has recently been proposed to bridge the gap between natural and
synthesized speech waveforms in statistical parametric speech synthesis and
provides fast inference with a moving average model rather than an
autoregressive model and high-quality speech synthesis with the adversarial
training. However, the human ear can still distinguish the processed speech
waveforms from natural ones. One possible cause of this distinguishability is
the aliasing observed in the processed speech waveform via down/up-sampling
modules. To solve the aliasing and provide higher quality speech synthesis, we
propose WaveCycleGAN2, which 1) uses generators without down/up-sampling
modules and 2) combines discriminators of the waveform domain and acoustic
parameter domain. The results show that the proposed method 1) alleviates the
aliasing well, 2) is useful for both speech waveforms generated by
analysis-and-synthesis and statistical parametric speech synthesis, and 3)
achieves a mean opinion score comparable to those of natural speech and speech
synthesized by WaveNet (open WaveNet) and WaveGlow while processing speech
samples at a rate of more than 150 kHz on an NVIDIA Tesla P100.
