.SH "DESCRIPTION" 
.PP 
This manual page documents briefly the 
\fBhts_engine\fR command. 
.PP 
This manual page was written for the \fBDebian\fP distribution 
because the original program does not have a manual page. 
Instead, it has documentation in the GNU       \fBInfo\fP format; see below. 
.PP 
\fBhts_engine\fR is a program that synthesize 
speech waveform from HMMs trained by the HMM-based speech synthesis 
system (HTS).
