NAME¶
open_jtalk — Japanese TTS system
SYNOPSIS¶
open_jtalk [
options] [
infile]
DESCRIPTION¶
This manual page documents briefly the
open_jtalk command.
This manual page was written for the
Debian distribution because the
original program does not have a manual page. Instead, it has documentation in
the GNU
Info format; see below.
open_jtalk is a program that synthesize speech waveform from Japanese
texts. It uses HMMs trained by the HMM-based speech synthesis system (HTS).

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.txt:
% open_jtalk -s 48000 -p 240 -a 0.55 \
-td tree-dur.inf -tm tree-mgc.inf -tf tree-lf0.inf \
