Galatea Toolkit for Linux (2009-02)
by Takuya Nishimoto (nishimoto [atmark] m.ieice.org)
The important changes from Galatea for Linux IPA final version (galatea-linux-ipa) released in August, 2003 are as follows.
== Platform
* The target platform is Ubuntu Linux 8.10 (32bit Desktop).
* The functions depending on distribution are not used.
* The installer of .deb format for the Ubuntu Linux was made.
* package : istc-galatea-morph, istc-galatea-engine, istc-galatea-dialog
* installed files
* /usr/local/{istc,istc-galatea-engine,istc-galatea-dialog}
* /usr/local/bin/galatea-{runner,generate}
* License: It is release for members of ISTC at present. Release as free software is planned after April 2009.
* The Java environment that Galatea Dialog Studio uses is OpenJDK 6.
* This uses /usr/share/java/js.jar as a JavaScript engine. This is changeable.
== Engines
* Each engine was updated.
* SRM : http://julius.sourceforge.jp/
* We shifted from Julian 3.x to Julius 4.x.
* SSM : http://sourceforge.jp/projects/galateatalk/
* The FSM was updated to v2.35.
* The FSM depends on GLUT. It uses freeglut3 now.
* A known problem: GLUT and 3D desktop cannot be used at the same time.
* http://d.hatena.ne.jp/mscp/20081207/1228634104
== Runner and Project
* The conventional galatea command became galatea-runner.
* Temporary files are written in at the .galatea directory of the home directory.
* The galatea-runner generates the configuration files of each engines from skeleton files dynamically.
* A galatea-generate command to generate a project was introduced.
* It is going to be expanded in future.
* The skeleton files of the 'skel' directory are in ERB format, and embedding of the Ruby language is enabled.
* The configuration files are generated using assigned values in system configuration (galatea.yml) and project setting (project.yml) dynamically.
In other words the correspondency of configuration files / skeleton files / runner is Model-View-Controller.
* galatea.yml and project.yml are written in ERB, and embedding of the ruby language is possible.
With the values evaluated in ERB, the generation of the configuration files from a skeleton file is performed.
* runner and generate use only a standard library of ruby1.8.
* We finished confirmation with ruby1.9, but ruby1.8 is used as the default.
== Galatea Dialog Studio
* The malfunction in the IPA final version that a work load of the CPU became very high was revised.
* Modified version is galatea-linux-v3.0a / gdm-src-1.0.1 of galatea-linux-ipa in sourceforge.jp.
* DS was implemented as a submodule controlled by AgentManager.
* DialogManager starts AgentManager (written in Perl) in the IPA-final version.
The current DS is one of the Galatea submodules communicating by a Galatea protocol by standard input/output.
The module name is DM. AgentManager starts DS.
* The major version of DialogManager was changed in 2.x from 1.x with this change.
* DialogManager for Linux changed a name in Galatea Dialog Studio (DS) from version 2.2.
* We confirmed the execution with Windows XP unofficially.
* The system configuration can be changed easily.
DS can communicate with each submodule in standard input/output.
A process can be started from DS.
* In the unofficial Windows mode, DS starts the processes of all submodules.
* The cookie was supported in HTTP protocol to acquire a document.
* Functions of Java 6 are used.
* Compatibility with PHP or Ruby on Rails which managed the session in cookie became higher.
* The DS introduced the GUI which was many functions.
* The status confirmation of the system, the selective display of the internal processing log are possible.
* The current DS does not use the Perl wrapper of the SRM.
The julius is started directly by DS, and DS and julius communicate with a socket.
The XML grammar of the speech recognition is converted into a Julius (Julian) format inside, and it is processed in mkdfa.
These functions work equally in the Windows environment.
The modules other than the SRM are started by AgentManager.
* The support of the XML speech recognition grammar is improved.
* In the IPA final version, the description corresponding to the Julius grammar was possible.
Support such as one-of elements is improved now.
Attributes such as slot or value can be used with the item tag.
* The functions related to the Julius grammar are available alone.
There is a sample in istc-galatea-dialog/files/tests/grammar/.
* The audio output corresponding to the audio tag of VoiceXML uses JavaSound.
== Submodules
* AM-MCL was implemented in Ruby.
* Control functions related to the output are added.
* The following modules were added to realize a natural head and facial movement.
* FS-MCL : It is a submodule managing the information such as the face of the agent of several kinds and the kind of the background, continuous movement
(implemented in Java).
* The facial autonomic movement functions that FSM provides are not used.
* PAR : It is a submodule carrying out several commands in synchronization with an output start of the voice synthesis
(implemented in Ruby).
* It is available with an all-of tag from VoiceXML.
* DIM : It is a submodule to control a blink and the eye contact depending on the utterance status of a user and the agent
(implemented in Ruby).
