This prototype of the FreeIconToSpeech activity has been updated with an alpha version at http://wiki.laptop.org/go/FreeIconToSpeech
This bundle [[Image:IconSpeak.activity-1.xo]] is an initial prototype of the OLPCIconSpeak.activity. Caution: It is likely to undergo rapid and radical change.The activity is based on [[Speak]]. The goal is to allow the user to build a message from an array of icons representing words. The message is then spoken using
speech synthesis.

The user of this activity clicks on a button in an array. A button may have an image (icon) or label (text). If the button corresponds to a
category, they are replaced by the icons/text from the next level down. In this case the first icon will be an up-arrow. Clicking on this icon will
return the user to the previous level. If the button is corresponds to a word - the word is copied to the output message. The word corresponding to a higher level can be selected by pressing the space bar while the mouse left button is down; otherwise, the next lower level will be displayed. Finally, the user can press the 'play' button and the message will be spoken by eSpeak.

The activity reads an .xml format file: asl.xml. This file specifies the icon and word correspondence. For example,

<ispk>
<category icon = 'someimage.gif'>text
<word icon = 'word.gif'>word
</word>
</category>
</ispk>

In the activity is a set of icons. The example set are in .gif format. However, .svg or .png formats could also be used. They are drawings
based on the American Sign Language [[http://library.thinkquest.org/10202/asl_dictionary_text.html]]. The activity looks for the icons in
the icons folder. It reads a file: asl.xml which specifies the icons and the corresponding words.

This version is replaced by [[Image:Ispeak-1.xo]]
