My background

2003-2007 Bachelor of Computer Science in UGM, Indonesia (

Final project title:

Difabel is a person with different abilities compare to people in general, (i.e. deaf, mute), they require special treatment to be able to access the computer. Software and hardware developer should involve them in design process. For difabel not all of information form can be obtained, i.e. deaf people just can obtain information in form of sound and Braille. World Wide Web is one of complete source of information. Then, VoIP technology is use internet to route sound. Combining both could produce information system for difabel.

Information system implemented as RSS (Really Simple Syndication or Rich Site Summary) reader of IVR (Interactive Voice Response). Configuration can do through web based interface, build using Ruby on Rails framework and RAGI (Ruby Asterisk Gateway Interface) API. Festival is text to speech software used to change RSS text into sound form. And Asterisk PBX used to access IVR from VoIP networking.

Results from this research are the sound of IVR is clearly enough, text speech in English. Configuration through web interface can work well. DTMF signal that send to IVR handled correctly. RSS URL that was not found handled using exception of connection stream and timeout.
