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

Demonstration notebook

  • Introduction notebook: a brief introduction to SynthesisFilters.jl. Synthesized audio examples (Japanese) are avaiable.

Supported Platforms

  • Linux
  • Mac OS X
  • Windows

Installation
