+svox (small footprint text-to-speech engine)
+
+The SVOX Pico engine is a software speech synthesizer for German, English
+(GB and US), Spanish, French and Italian. SVOX produces a clear and
+distinct speech output made possible by the use of Hidden Markov Model
+(HMM) algorithms.
+
+The package includes the pico2wave utility, and everything else from
+the Debian packages libttspico-data, libttspico-dev, libttspico-utils,
+and libttspico0.

+.TH PICO2WAVE "1" "June 2018" "pico2wave" "SlackBuilds.org"
+.SH NAME
+pico2wave \- Small Footprint TTS
+.SH SYNOPSIS
+.B pico2wave
+\fB-w\fR
+\fI<filename.wav>\fR
+[ \fB-l\fR \fI<language>\fR ]
+[ \fI<words>\fR ]
+.SH DESCRIPTION
+.B pico2wave
+is a small footprint Text to Speech utility, using the SVOX Pico
+engine \fB[*]\fR. It converts
+text given on the command line (or standard input, if no
+\fI<words>\fR on command line) to audible speech, and writes
+to a RIFF .wav file.
+.PP
+The generated wav files are PCM, 16-bit mono, 16KHz sampling rate.
+.PP
+\fB[*]\fR The SVOX Pico engine is a software speech synthesizer for German, English
+(GB and US), Spanish, French and Italian. SVOX produces a clear and
+distinct speech output made possible by the use of Hidden Markov Model
+(HMM) algorithms.
+.SH OPTIONS
+.TP
+\fB\-w\fR, \fB\-\-wave\fR=\fIfilename\fR.wav
+Write output to this WAV file (extension SHOULD
+be .wav). This option is required: \fBpico2wave\fR
+cannot write to standard output (not even if you
+use \fB-w /dev/stdout\fR, sorry). If the file
+already exists, it will be \fBoverwritten\fR with no
+confirmation or warning.
+.TP
+\fB\-l\fR, \fB\-\-lang\fR=\fIlang\fR
+Language (default: \fBen\-US\fR). The languages supported are
+currently \fBde\-DE\fR, \fBen\-GB\fR, \fBen\-US\fR,
+\fBes\-ES\fR, \fBfr\-FR\fR, \fBit\-IT\fR.
+.SS "Help options:"
+.TP
+\-?, \fB\-\-help\fR
+Show help message
+.TP
+\fB\-\-usage\fR
+Display brief usage message
+.SH EXAMPLES
+.TP
+.B
+pico2wav -w test.wav 'Hello, world.'
+.PP
+Creates a file \fBtest.wav\fR containing the words "Hello, world."
+.TP
+.B
+echo 'Hello, world.' | pico2wav -w test.wav
+.PP
+Same as above, reading from standard input.
+.TP
+.B
+pico2wav -w test.wav < gettysburg_address.txt
+.PP
+Convert an entire text file to speech.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+# - The _8 in the version number is the Debian build number, keep it
+#   in sync with future Debian updates.
+# - "Upstream" here is Debian, not Android. Debian has svox's homepage
+#   listed as "www.android.com", it seems more useful to set HOMEPAGE
