voiceTEXT

voiceTEXT is a method for instantly sending messages using voice over a phone line. The process begins with the sender connecting to the server using a phone (cellular or land or internet, e.g. voice over IP). After the sender connects s/he composes a message using her/his voice. The message is stored on the server. The voiceTEXT system then places a call to the designated recipient. When the recipient answers the call, the voiceTEXT system plays the recorded message. The recipient can reply to the voiceTEXT message with a new voiceTEXT message using her/his voice, meaning the recipient becomes a sender.

The voiceTEXT system was implemented using VoiceXML (Voice eXtensible Markup Language) and CCXML (Call Control XML).

1. Uses call connections or voice over IP to deliver the message vs. SMS.
2. The message is an audio stream vs. text
