CAIVIAR capiserver using realspeak

Finally....

The caiviar server source 0.3.5 has some flaws when compiling/using it in relation to Scansoft RealSpeak TTS engine under Linux.

Currently, I can't make the thing connect to a Scansoft TTS-server, but I can use the engine statically linked in.

In what follows, I assumed (change for your needs):

• the installation of scansoft realspeak is in REALSPEAKDIR (mine: /opt/scansoft/tts)
  REALSPEAKDIR=/opt/scansoft/tts/
  
• the caiviar source is in CAIVIARDIR (mine: /tmp/caiviar-0.3.5)
  CAIVIARDIR=/tmp/caiviar-0.3.5/
  

this is what I did:

fix ${CAIVIARDIR}server/RealSpeak.cpp

I *did* alter more than minimally needed. Most importantly:

• change the ".\\Engine" string you find into the directory needed for your system. (I changed it to "/opt/scansoft/tts/engine"
  
• replace tts_language by language
  
• replace stdup by strdup
  
• if needed, change or adjust the code around "Setting language to" to have YOUR constant(s) (for your specific language).
  You should consult ${REALSPEAKDIR}api/inc/lh_ttsso.h (or your RealSpeak documentation) for correct values/constants.
  
  Check after installation (see below) the configuration file (probably /etc/ivr.properties the line stating realspeak.language= should have one of the strings caught by that functionality. (default is "german").
  

incorporate RealSpeak includes and objects (of your RealSpeak obtained installation)

cp ${REALSPEAKDIR}api/lib/* ${CAIVIARDIR}server/TTS
cp ${REALSPEAKDIR}api/inc/* ${CAIVIARDIR}server/TTS

configure and compile caiviar (capiserver)

cd ${CAIVIARDIR} && ./configure --enable_realspeak && make

install caiviar (capiserver)

cd ${CAIVIARDIR} && sudo make install

create sysv-init script:

create /etc/init.d/capiserver

#!/bin/bash
# Filename: capiserver
# Version: 1.0
# Author: Dieter Demerre 
# Description
#   SysV-init script to launch capiserver
#
#   usually known as: /etc/init.d/capiserver
#
NAME="CAIVIAR CAPI Server"
CAIVIARCONFIG=/etc/ivr.properties
CAIVIAR_PIDFILE=/var/run/capiserver.init.pid
CAIVIAR=/usr/local/bin/capiserver
if [ ! -x ${CAIVIAR} ]; then
  echo -n "\nError: Could not find ${CAIVIAR} executable.\n" >&2
  exit 5
fi
test -f ${CAIVIARCONFIG} || echo "WARNING no ${CAIVIARCONFIG} config found\n" >&2
case "$1" in
  start) startproc -f -p ${CAIVIAR_PIDFILE} ${CAIVIAR};;
  stop) killproc -p $CAIVIAR_PIDFILE -TERM ${CAIVIAR};;
  restart) $0 stop ; $0 start;;
  *) echo -n "unknown action.\nknown actions are: (start|stop|restart)\n"; exit ;;
esac

link to /etc/init.d/capiserver from the expected sysV runlevel directories (distribution specific, maybe use system-tools to set the links).

for level in 2 3 5;
do 
  sudo ln -sf ../init.d/capiserver /etc/init.d/rc${level}.d/S99capiserver;
done
