REPROS

NAME

repros - change speaking rate and or pitch of speech (advanced)

SYNOPSIS

repros (-I) (-i item) (-m MBROLAcontrolfile) (-v) (-j) (-O txoffset) (-P txpercent) file

DESCRIPTION

repros is a program to modify the pitch and duration of an utterance. It uses the PSOLA algorithm and requires a set of pitch-epoch annotations. These can be generated from a Laryngograph signal using Lx->Tx conversion, followed by Tx->An conversion.

Control data for the change in prosody is specified by a text file in MBROLA format. This file consists of a series of lines, one per annotated segment in the target file. Each line contains: segment label, new segment duration in ms, new fx contour specified as series of pairs: % position through segment, fx value in Hz. The segment label '_' matches initial or final silence in the file.

OPTIONS

-I Identify program name and version number.

-i item Select input item number.

-m MBROLAcontolfile Specify MBROLA format control file for prosody change.

-O txoffset Shift TX with respect to speech (0.001s is typical value). Default 0.

-P txpercent Reduce pitch windows to this %age of available time. Deafult 100.

-j Add pitch jitter to hide artifacts.

-v Verbose mode.
