\"open youtube dot com\"Create custom commands:To create custom commands in Palaver and run shell scripts as voice commands, you required tobackup the file main.dic and insert new entries on it, depending on the language installed, forexample:terminal open x-terminal-emulatorcairo open cairo-dockkill conky kill-conkyWhere:kill conky = The keyword say: \"Open... kill conky\"kill-conky = The name of the script to run.But LiSpeak works differently and is more rigid: It only runs programs, for example, the editorNetbeans IDE have not been added to any file but when I say to the assistant to open it like this:CTRL + L, open Netbeans, CTRL + Lthe program opens normally. With Palaver you required to add the program explicitly to the setupfiles.So, the only way to run a shell script is to make the script a program.Steps to make scripts programs:1. Create the shell script.2. test the shell script running the script:$ sh script.sh3. Optionally, make the shell script a systemd or a sysvinit service. Guides to create the script as aservice:References:Guide:Systemd4. Create a symlink from the program to a bin directory, /usr/bin or /usr/local/bin. Review this guideto install Sublime Text Editor to proceed with the creation of the link:References:Guide: Sublime Text Editor5. Test your new program or service:$ myprogramOnce the program is ready, just use LiSpeak to run it:$ open myprogram
Tip:Create scripts to run as programs to close programs, for example:$ tuxclosefirefox$ bubbleshutdownTesting the file main.dic:Speak something the program should say or write in the notifier (Later on we will notice the are twoplaces where program can write, the Bubble and a slicer window that appears from the notificationare of Gnome):Say: \"This is Esteban Herrera.

CTRL + LThe program as a startup App:It is not required because CTRL + L will start the service and record simultaneously, but if you want toadd the program as a startup application:IMPORTANT: The best way to make the program a startup app is to focus the Mic on the Gnomenotifications' area, and then make RIGHT CLICK on it, and then choose the menu option \"settings\",and then click the tab \"general\" and check the right option.Also, it is possible to (untested):Add the program as a service to systemd or sysvinitAdd the program as a startup app in Gnome or FluxboxSee my Screensaver guide here for details:References:Guide:XscreensaverUse the command: python /home/esteban/.lispeak/services/HTTPServer.serviceHow to install a graphical tool to configure Notify-OSD:You can find the Ubuntu source in the Ubuntu PPA: https://launchpad.net/ubuntu/+ppasSearch for: 'notifyosdconfig'.Click on the package, to reach the page with the link \"View package details\" and then click on it.

Now, the program 'notification-daemon' has the \"rc\" mark. There is a command to purge these filesbut I don't remember it right now. I am not scared about the un-installation, due to the installation of'notify-osd' said that it would provide a 'notification-daemon'. However there's not 'notification-daemon' in the commands.

But again, the colors shown, like the blue background, do not correspond to the colors described inthe source under /wrk, so the system is doing something after that to show me another look.What happened to notification-daemon? It's kind of confusing:The program 'notification-daemon' was substituted with the notify-osd from the PPA repos.Alternative Solution:Use the notification style = system instead of = LiSpeak:You will see the notifications like a slider message box showing up since the notifications area, insteadof in a bubble on the left top of the screen.CUSTOMIZATION:Activate the option to Speak responses:RIGHT CLICK on the Mic on the Gnome notifications area an select \"settings\".You will hear a voice answering your questions.Create or download more plugins:Point your browser at, and create an account here: http://lispeak.bmandesigns.com/homeTest espeak TTS:$ espeak -v mb-us1 \"This is a test\"$ echo \"Hello World\" > texttospeech.txt$ espeak -v mb-us1 -f texttospeech.txtTTSs:References:Web: http://askubuntu.com/questions/53896/natural-sounding-text-to-speechWeb: http://blends.debian.org/accessibility/tasks/speechsynthesispico2wave:This TTS is not installed but the option appears in the LiSpeak settings.The package that corresponds to this TTS is logged in the Official Debian repositories as a non-free,named \"svox\" here: https://packages.debian.org/source/jessie/svoxOn the page, do the section Download the source:Make right click in the files to copy their locations.Download the files.Build the DEB package from sources.Install the package.Note: I received an error during the installation step after building.Output: This package is uninstallable Dependency is not satisfiable: libttspico-data

I am going to come back to know what is going on with the application sometimes. unfortunately I amlooking for something that works almost Out fo teh Box. Web site: http://sirius.clarity-lab.org/index.html%3Fp=9.htmlFrom the email lists:Semantic databases:Could anyone point me in the right direction as to how to be able to get the QA server to answerquestions from my own data? I'm especially interested in being able to answer questions about datacontained in a semantic database (RDF). I imagine this may involve somehow turning the normalizedquestion into a SPARQL query somehow.Hey, i am interested in that too. As soon, as sirius is more a shell, you should extendhttps://mu.lti.cs.cmu.edu/trac/Ephyra/wiki/OpenEphyra project.Quick search about OpenEphyra + RDF i found the answer from a contributorA knowledge annotator only makes sense if you have a source that already provides answers tospecific kinds of questions in a way that makes it easy to extract them. The format doesn't reallymatter: it can be a relational database, a website that follows a certain template (such as the CIAWorld Factbook), a web service (e.g. providing weather information) etc. An ontology may work too.Knowledge annotators are intended as a mechanism for extracting answers to frequent types ofquestions with high confidence from specialized sources. It takes some manual effort to create aknowledge annotator (i.e. write a wrapper for a particular source), but it is a rather save way toimprove the performance if you have some idea about the distribution of the questions.Technically, you could extract question-answer pairs from an encyclopedia and store them in adatabase (e.g. a table containing frequently seeked properties of a person, such as date of birth,profession etc.), and then integrate this DB with a knowledge annotator. This may make sense if youare concerned about the runtime of the system.So if you will build such base please inform me, that's an really interesting thing!Web interface:The web interface is a prototype and probably should not be used as a final web front-end to runSirius, more of a starting point. I would also recommend starting from the provided shell scripts andeven implementing your own. We are currently working on front-end(s).Sirius client:https://github.com/d4ndo/sirius-client

You can now do one of two things, install individual packages, or else update yoursystem to KXStudio (recommended).There are two ways to go about updating your system to KXStudio. The first involves installing all ofKXStudio available software packages AND updating your desktop environment to KDE, which is thedefault used in KXStudio. If you want to do this, go to your software center/package manager andinstall the following packages:$ sudo apt-get install kxstudio-desktop$ sudo apt-get install kxstudio-meta-all
If you would like to install all software packages from KXstudio but keep your existing desktopenvironment as default (Unity, XFCE, LXDE) you can install the following packages:$ sudo apt-get install kxstudio-default-settingsSay.. use the packages since Gnome. KXStudio Desktop spends much resources like the swappingpartition. Also Gnome is the only Desktop environment fully supporting digital USB sound andmicrophones, like my Microsoft LX 3000 Headset. Neither XFCE or LXDE support this device.Issues:KXStudio is working perfectly, and the migration to Debian is almost done, but if you run their appssince Gnome you'll notice that the apps look very basic, perhaps QTK or pure basic GTK or QT, due toGnome uses GTK and KDE QT to generate desktop GUIs.

FirefoxIt's easy to install Firefox browser on Debian 8.Debian by default comes with Iceweasel web browser instead of firefox. Although it is recommendedto use Iceweasel you may have a need to install firefox are here is a simple way how to install firefoxon Debian Jessie by using Linux mint's debian import repository.Firstly edit your /etc/apt/sources.list file and add the following line:deb http://packages.linuxmint.com debian importAt this point on my sources.list file it looks like this:# Mint# Packages: Firefox,#deb http://packages.linuxmint.com debian importUpdate your package list:# apt-get updateIf there is the unavailble gpg key 3EE67F3D0FF405B2 problem:# gpg --keyserver pgpkeys.mit.edu --recv-key 3EE67F3D0FF405B2# gpg -a --export 3EE67F3D0FF405B2 | apt-key add -# apt-get updateThe above command will fetch mint package repository list. As a last step install firefox browser:# apt-get install firefoxYou may want to DISABLE Linux Mint's package repository after Firefox installation by commenting anewly added line in apt sources.list.Firefox Web Browser installation on Debian 8 Jessie LinuxNote:All be files fetched with APT will be downloaded to /var/cache/apt/archives/ before their installation.In this case I got the file firefox_37.0~linuxmint1+betsy_amd64.deb which seems a Mint file, butworks perfectly on Debian 8.To run the browser:You will see the icon, but on the command line do:$ fire (And press TAB key on the keyboard)Output:You should see firefox and firefox.realTest the two options to make sure which is Firefox and which isn't.

It can be embedded inside a webpage, in which case it will work only in that specific web page.Examples of common plugins: Flash, Java, Microsoft Silverlight, Apple Quicktime, Adobe Reader.What is an Extension?Extensions, or “add-ons,” can add onto the browser user interface and process pages that the browserloads. Although you might think they are similar, in fact extensions are not the same as plugins; theyaffect the web browser itself, as well as the page. Some examples of important or necessary add-onsinclude: Adblock Plus, Firebug, Microsoft .NET Framework Assistant.
Below you will find instructions on how to remove or disable unnecessary plugins and extensions forGoogle Chrome:Open Google Chrome and click the Chrome menu on the browser toolbar.Click Tools.Select Extensions.Click the trash can icon by the extension you'd like to completely remove.When the confirmation dialog appears, click Remove.You can also temporarily turn off an extension by disabling it on the Extensions page.Clear browsing cache and cookies:To empty the cache of your internet browser, follow the next steps:Open Google ChromeClick on the Chrome menu on the browser toolbar.Select Tools.Select Clear browsing data.In the dialog check the boxes for the types of information that you want to remove (Clear browsinghistory, Clear download history, Delete cookies and other site and plug-in data, Empty the cache –these are checked by default, and it is recommended to keep them checked)Use the dropdown menu at the top of the window to select the amount of data that you want todelete. Select the beginning of time to delete everything.Click Clear browsing data.Reset your browser settings:Click the Chrome menu on the browser toolbar.Select Settings.Click Show advanced settings and find the \"Reset browser settings” section.Click Reset browser settings.In the dialog window, click Reset.Note: when you check \"Help make Google Chrome better by reporting the current settings\" you areanonymously sending Google your Chrome settings.Great suspender:It's an extension to Automatically suspend unused tabs to free up system resources.Unloads, parks, and also suspends tabs to reduce memory footprint of chrome.Tabs can auto-suspend after a configurable period of time or be suspended manually. Tabs can bewhitelisted to avoid automatic suspension. Suspended tabs are retained after closing and reopeningbrowser, preventing many tabs from all reloading after a restart.

It is possible to download a newest version of Oracle Java from the Ubuntu PPA repositories butDebian has not PPA to be able to 'apt-get install' from those repos. In some cases you have to knowhow to simply download with wget from PPAs, if possible. Anyways the compilation worked well and itis not necessary.I am not storing the packages in /usr/src because they are DEB packages, but it is a good idea to buildthe sources under usr/src /usr/local/srcIt is possible to switch between plugin, for example from iced-tea-plugin to icedtea-6-plugin. Itdepends on the browser, system, plugin and Java versions. Basically you have to change a symlink tothe plugin. Research on google.Java would stop working on browsers due to JavaScript Today is the Internet language and if thebrowsers like Internet Explorer (Deprecated), Spartan (Under testing) and Firefox deprecate the NPAPIwhich allows to connect Java client-server. The NPAPI has many errors, and that is the reason whyGoogle removed it from its browser.
