Mel spectrogram inversion with stable pitch

Web28 jun. 2024 · I am designing and implementing a Speech-to-Text with Deep Learning and when I used n_mels=64, it didn't work at all, it only works with n_mels=128. Could it because I am normalizing it before injecting it to the network? I am using the librosa.utils.normalize function and it normalizes the mel spectrogram between -1 and 1. WebKey to improving the pitch stability is the choice of a shift-invariant target space that consists of the magnitude spectrum and the phase gradient. We discuss the reasons that inspired us to re-formulate the vocoder task, outline a working example, and evaluate it on musical signals.
