SynthesisFilters

SynthesisFilters.jl provides waveform generation filters for speech synthesis, especially from mel-generalized cepstrum.

Note that this package is built on top of SPTK.jl. The package is designed to provide a Julia-like interface with a focus on speech waveform synthesis. A part of the core is re-writen in Julia language from Speech Signal Processing Toolkit (SPTK).

Features

• LMADF: Log magnitude approximation digital filter for synthesis from cepstrum
• MLSADF: Mel-log spectrum approximation digital filter for synthesis from mel-cepstrum
• MGLSADF: Mel generalized-log spectrum approximation digital filter for synthesis from mel-generalized cepstrum
• AllPoleDF: All-pole digital filter for synthesis from LPC
• AllPoleLatticeDF: All-pole lattice digital filter for synthesis from PARCOR
• LSPDF: LSP digital filter for synthesis from LSP
