This Standard specifies requirements for the design of the user interface in Interactive Voice Response (IVR) systems where the primary user input is by speech.
User input by Short Message Service, Wireless Application Protocol and General Packet Radio Service is outside the scope of this document.
NOTE: Where the user interface allows input by means of both DTMF and speech, the requirements of AS/NZS 4263 should apply to DTMF input except where this Standard includes specific requirements for multi-mode input.
