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

       -tm tree  Show version of program.

       -tf tree  decision tree files for Log F0

       -tl tree  decision tree files for low-pass filter

       -md pdf	 model files for state duration

       -mm pdf	 model files for spectrum

       -mf pdf	 model files for Log F0

       -ml pdf	 model files for low-pass filter

       -dm win	 window files for calculation delta of spectrum

       -df win	 window files for calculation delta of Log F0

       -dl win	 window files for calculation delta of low-pass filter

       -od s	 filename of output label with duration

       -om s	 filename of output spectrum

       -of s	 filename of output Log F0

       -ol s	 filename of output low-pass filter

       -or s	 filename of output raw audio (generated speech)

       -ow s	 filename of output wav audio (generated speech)

       -ot s	 filename of output trace information

       -vp	 use phoneme alignment for duration

       -i  i f1 .. fi
		 enable interpolation & specify number(i),coefficient(f) [1][1--]

       -s  i	 sampling frequency [16000][1--48000]

       -p  i	 frame period (point) [80][1--]

       -a  f	 all-pass constant [0.42][0.0--1.0]

       -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

       -ef tree  decision tree files for GV of Log F0

       -el tree  decision tree files for GV of low-pass filter

       -cm pdf	 filenames of GV for spectrum

       -cf pdf	 filenames of GV for Log F0

       -cl pdf	 filenames of GV for low-pass filter

       -jm f	 weight of GV for spectrum [1.0][0.0--2.0]

       -jf f	 weight of GV for Log F0 [1.0][0.0--2.0]

       -jl f	 weight of GV for low-pass filter [1.0][0.0--2.0]

       -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 
	      input.lab
