Today, VoiceXML is the standard scripting language for rendering web pages over the telephone. VoiceXML builds on the basic concept and rules set by XML. VXML is W3C and IEEE standard. VXML is portable to any VXML platform. It is much stable, mature and reliable language. Interactive applications contain prerecorded audio, grammars defining words that could be recognized, and DTMF key input. Also, by saying something or by pressing the keypad on the phone the user moves to different pages. This paper describes how VoiceXML is defined and how it works. This paper includes information about IVR & its structure. It also describes about TTS. This paper also describes difference between ASR & Transcription. Our conclusion is that VXML is a nice way to make voice-enabled applications.
