Here is the list of available software:

Inverse Filter

Inverse Filter is used to obtain estimates of the shape of the harmonic part of the glottal source. In source-filter theory, the vocal tract is modeled as an all-pole filter shaping the input glottal source, and radiation at the lips is modeled by a differentiator. To recover the glottal source, these factors must be canceled out. This program can be used to do that.

Sky

Sky is an analysis package specialized for acoustic analysis of voice. It is constantly evolving as new measures and analysis approaches appear in the literature.

Synthesis

The voice synthesizer is a formant synthesizer, based on the source-filter theory of speech production. This synthesizer differs from most other formant synthesizers in the precision with which the source can be modeled, and in the degree of interactivity. It is also limited at present to modeling of vowels with steady-state resonances (although instabilities in the source functions can be modeled in great detail.)
