Parameter generation¶
Numpy implementation of speech parameter generation algorithm.
build_win_mats (windows, T) |
Builds a window matrix of a given size for each window in a collection. |
mlpg (mean_frames, variance_frames, windows) |
Maximum Parameter Likelihood Generation (MLPG) |
mlpg_grad (mean_frames, variance_frames, …) |
MLPG gradient computation |
unit_variance_mlpg_matrix (windows, T) |
Compute MLPG matrix assuming input is normalized to have unit-variances. |
reshape_means (means, static_dim) |
Reshape means (T x D ) to (T*num_windows x static_dim ). |
