: Note: IBM no longer distributes [[http://www-4.ibm.com/software/speech/dev/ttssdk_linux.html Viavoice]]. Use espeak or voxin.

This page describes installing IBM's !ViaVoice for use with EmacSpeak.

=== Installing ViaVoice ===

Some requirements for this setup (good luck finding these):

* The [b]IBM !ViaVoice TTS Runtime-kit for Linux[/b]
* The [b]IBM !ViaVoice TTS SDK for Linux[/b]

From them, you'll need ##viavoice_tts_rtk.tar##. Getting the ##sdk.tar## file isn't necessary.

They contain ##.rpm## files, which you can install on RedHat or use [[https://wiki.debian.org/Alien Debian Alien]] to convert them to ##.deb##s:

{{{
# Perform RPM -> DEB file conversion + installation.
alien -i filename.rpm
}}}

=== The Outloud Speech Server ===

Required: ##tclx##, so on Debian, ##apt-get install tclx8.3 tclx8.3-dev## first.

The Emacspeak *Outloud speech server* allows Emacspeak to interface with !ViaVoice. It
is in the ##servers/linux-outloud## folder in Emacspeak. The ##NOTES## file in this directory describes compilation.

: You may need to change the ##-ltcl## option in the Makefile to something like ##-ltcl8.3##.

You may have to add an *include path* so that ##tcl.h## gets found, or edit the ##tcleci.cpp## file to make the <code>#include <tcl.h></code> line fit to your systems needs. (e.g. on my system, I put ##tcl8.3/tcl.h## there).

Make and install the speech server.

You should now be able to invoke ##emacspeak -o## (##-o## calls the Outloud speech server).
Look at the emacspeak script to see how this works; basicly setting ##DTK_PROGRAM=outloud## in your shells environment should do the trick too.

Getting Auditory Icons working:

You may have noticed that the outloud speech server tries to use a /usr/bin/stdiosynth to generate auditory icons.
This will work on some systems which have /dev/synth0. My sblive doesn't have that, and so stdiosynth doesn't work.
But my sblive is multichannel capable. So I can use /dev/dsp concurrently. Here is my .emacs setup to make this work.
Be careful, it may be necessary that you use the CVS version of Emacspeak for this to work right.
