htsengine(1) General Commands Manual htsengine(1)
NAME
hts_engine -- HMM-based speech synthesis engine
SYNOPSIS
hts_engine [options] [infile]
DESCRIPTION
This manual page documents briefly the hts_engine command.
This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has docu-
mentation in the GNU Info format; see below.
hts_engine is a program that synthesize speech waveform from HMMs trained by the HMM-based speech synthesis system (HTS).
OPTIONS
A summary of options is included below.
-td tree decision tree files for state duration

-g i gamma = -1 / i (if i=0 then gamma=0) [0][0--]
-b f postfiltering coefficient [0.0][-0.8--8.0]
-l regard input as log gain and output linear one (LSP)
-r f speech speed rate [1.0][0.0--10.0]
-fm f add half-tone [0.0][-24.0--24.0]
-u f voiced/unvoiced threshold[0.5][0.0--1.0]
-em tree decision tree files for GV of spectrum

-k tree GV switch
-z i audio buffer size [1600][0--48000]
infile label file
option '-d' may be repeated to use multiple delta parameters. generated spectrum, log F0, and low-pass filter coefficient sequences are
saved in natural endian, binary (float) format.
EXAMPLE
If you installed hts-voice-nitech-jp-atr503-m001 in the current directory, the following command let you make a voice file from input.lab:
% hts_engine -s 48000 -p 240 -a 0.55
-td tree-dur.inf -tm tree-mgc.inf -tf tree-lf0.inf
-tl tree-lpf.inf -md dur.pdf -mm mgc.pdf
-mf lf0.pdf -ml lpf.pdf -dm mgc.win1
-dm mgc.win2 -dm mgc.win3 -df lf0.win1
-df lf0.win2 -df lf0.win3 -dl lpf.win1
-em tree-gv-mgc.inf -ef tree-gv-lf0.inf -cm gv-mgc.pdf
-cf gv-lf0.pdf -k gv-switch.inf -ow output.wav
