===== Purpose =====

The VXI%%*%% VoiceXML browser integrates an HTTP client interface to manage Text-to-Video contents. This allows to dynamically generating a video content from text. TTV includes audio using the Text-to-Speech interface to access text-to-speech features. The advantage however, of using the HTTP connector is that the “speech” generated is cached by the VoiceXML Browser, and re-used the next time.  The text is posted via an HTTP request then the server responds with a standard h263/.h264 or mp4/3gp file.  Users can use the TTS to generate menus prompts, for example.

===== Definition =====

The Text-to-Video works much like Text-to-Speech.  It can be used to dynamically generate a video, either static or with animation, from text.  The text comes from the <prompt> VoiceXML tag and if the attribute language is either “video” or “text.”

Example:

<code>
<prompt bargein="false" xml:lang="text"> 
Welcome
Camera Service!
</prompt>
</code>


NOTE:

The HTTP Text-to-Video generates an .h263/.h264 or mp4/3gp file.

===== Installation =====

First unzip and untar the text2video package by using the command:

<code>
# tar xvzf text2video_Vx.x_date.tar.gz
</code>

Next, go to the directory of the text2video and type the following command:

<code>
# cd text2video_Vx.x_date
# ./install.sh
</code>


NOTE:

Install the script on your Apache/PHP server. Configure the VoiceXML Browser (Text-to-Video Option) and restart the VoiceXML interpreter to get the new configuration.
