legacy_STRAIGHT

A vocoder framework which had been widely used in research community since 1999.

SparkNG

MATLAB real-time/interactive speech tools. This series is obsolete. SP3ARK is the up-to-date series (will be).

FVN

FVN is now obsolete. Please use CAPRICEP instead. I will stop updating this tool. Frequency domain variants of Velvet Noise, a flexible building unit for speech synthesis, psychoacoustic research and acoustic measurement.

YANGstraight_source

Analytic signal-based source information analysis for YANGstraight and real-time interactive tools

CAPRICEP

An extended TSP (Time Stretched Pulse). CAPRICEP substantially replaces FVN. CAPRICEP enables interactive and real-time measurement of the linear time-invariant, the non-linear time-invariant, and random and time varying responses simultaneously.
