Usage: voice.pl [options] [path to dir]
-V
Create voice file. You must also specify -t and -l.
-C
Create .talk clips.
-t=<target>
Specify which target you want to build voicefile for. Must include
any features that target supports.
-i=<target_id>
Numeric target id. Needed for voice building.
-l=<language>
Specify which language you want to build. Without .lang extension.
-e=<encoder>
Which encoder to use for voice strings
-E=<encoder options>
Which encoder options to use when compressing voice strings. Enclose
in double quotes if the options include spaces.
-s=<TTS engine>
Which TTS engine to use.
-S=<TTS engine options>
Options to pass to the TTS engine. Enclose in double quotes if the
options include spaces.
