Overview: What is Tukh?
Tukh is small village downstream of Cairo. For current purposes, however, Tukh is a set of scripts for working with the Cairo MRCP server. Tukh has two main objectives:
- enable Cairo to be run on Linux
- enable Cairo to use recognition resources based on HTK.
As the scripts are written in Python, they /may/ develop into a basic python API for Cairo.
Current status
I have rewritten the launch and demo .bat scripts in Python. They work more or less identically to the .bat scripts. I haven't yet tested them on Linux.
Set up
Installation
No installation is necessary. The scripts will run from wherever they are unpacked.
Configuration
Some configuration is necessary, however. The file tukh/config.py contains information which you should check tallies with your system. The current (or at least a recent) config.py looks like this:
#! /usr/bin/python cairo_home = 'C:\cairo-0.1-bin' cairo_version = '0.1'
Usage
The scripts in tukh are used exactly as the launch and demo .bat scripts of the same name in Cairo. Usage for these is specified in the Cairo Getting Started page.
Help wanted
The Windows Environment
Java or "C:\Program Files\Java\jdk1.6.0_01\bin\java"
The launch scripts will work with either java or "C:\Program Files\Java\jdk1.6.0_01\bin\java", but the demo scripts will only work with the former. The following was copied from a Command Prompt window:
C:\Documents and Settings\ivan\My Documents\iau\llaisdy_svn\tukh>python demo-spe
echsynth.py
"C:\Program Files\Java\jdk1.6.0_01\bin\java" -Xmx200m -Dlog4j.configuration=log4
j.xml org.speechforge.cairo.demo.tts.SpeechSynthClient 42046 "Congratulations! Y
ou have successfully installed the Cairo speech server. Please try the other dem
os to test out Cairo's speech recognition capabilities."

operable program or batch file.

looking up: rmi://192.168.0.2/ResourceServer
Is this something to do with the Command Prompt environment not being able to handle too many quotes?
start "name" on the command line
The {rserver,receiver1,transmitter1}.bat files run launch.bat using a line of the form:
start "name" command
For example, rsever.bat has:
set CLASS=org.speechforge.cairo.server.resource.ResourceServerImpl start "rserver" launch %CLASS%
What is the significance of the start "name" part? rserver.bat (et al.) works just as with only launch %CLASS%. What does the start "name" prefix do, and what am I missing by not using it?
Cairo
Querying the server
How can you check to see whether an MRCP server is running? For example, so that receiver1 could do this check, and launch a server if necessary.
Related, does Cairo support the OPTIONS request (i.e., for a client to query the server's capabilities)? If not, how can a client find out what resources are available from the server?
TODO
- use one script for all three launches (rserver, receiver, transmitter).
- get running on linux.
- get running with htk instead of sphinx (nb: or convert htk acoustic model to Sphinx4 engine).
