VOCSYN

NAME

vocsynth - general purpose filterbank synthesizer

SYNOPSIS

vocsynth (-i item) (-w|-m|-x spitem) (-s srate) file

DESCRIPTION

vocsynth is a general-purpose means for converting filterbank analyses back into speech signals. Energies are taken from a COEFF item analysed using voc8, voc19, voc26 or filtbank. Fundamental frequency is taken from a FX item (none in 'whisper' mode), while voicing mixtures can be optionally supplied in a TRACK item.

Options and their meanings are:

-I Identify program and version number.

-i item Select input item.

-w "Whisper" data, when no FX is present.

-x spitem Use external excitation from given speech item (must match in sampling rate).

-m Use voice mix track to control degree of periodic excitation. Designed for use with output of vdegree(SFS1) program.

-s samplerate Specify synthesis output sampling rate (should be bigger than twice top of highest filter).

INPUT ITEMS

FX Fundamental frequency contour, used for voice-switch and Fx.

CO Filterbank energies generated by voc8, voc19, voc26 or filtbank.

SP (External excitation mode) Input signal to filter.

TR (Optional) Voicing mixture track (see vdegree).

OUTPUT ITEMS

SP Speech waveform.
