How we support industry standards
Open standards promote application portability and protect your investment.
Nuance believes strongly in open standards that don’t lock you into one vendor. Standards-based solutions offer application portability and protect your investment and we’ve taken a leadership role in establishing standards for speech-enabled applications and communications protocols. Nuance is active with standards bodies such as the Worldwide Web Consortium (W3C) and the Internet Engineering Task Force (IETF). We are also a member of the VoiceXML forum. Over the years, we have co-authored and contributed regularly to many open standards.
VoiceXML is a language for creating telephony-based speech-user interfaces. It uses speech recognition and touchtone for input and pre-recorded audio and text-to-speech for output. It is based on the Worldwide Web Consortium's (W3C's) Extensible Markup Language (XML). The Nuance Voice Platform was one of the first three platforms certified as VoiceXML 2.1 compliant by the VoiceXML forum.
