hts_engine -- HMM-based speech synthesis engine
hts_engine [options] [infile]
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).
A summary of options is included below.

-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--]
-s i sampling frequency [1--48000]
-p i frame period (point) [1--]
-a f all-pass constant [0.42][0.0--1.0]
-g i gamma = -1 / i (if i=0 then gamma=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

-jl f weight of GV for low-pass filter [1.0][0.0--2.0]
-k tree GV switch
-z i audio buffer size [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.
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
