VoiceXML is a standards-based markup language for creating and deploying telephony-based voice user interaction applications. In simple terms, VoiceXML makes it possible to access information from databases and the web via telephones and other voice devices.
A wide range of applications can leverage VoiceXML technology. These include:
- Communication services, such as voice-activated dialing, voice mail and unified messaging
- Information services, such as voice-access portals providing weather forecasts, driving directions, business news and sports scores
- E-commerce, including business-to-consumer and business-to-business applications, such as order status reports
- Customer relationship management, such as call-center applications
VoiceXML services can provide an efficient, easy-to-use voice user interface that contains sequences of interactive dialogs between the user and the application. These services can integrate rich web content and operate within the telephony infrastructure of service providers and enterprises.
From a business standpoint, VoiceXML makes it possible for service providers to develop, test and roll out applications in less time and at a lower cost. At a technical level, VoiceXML leverages the communications industry's expertise with existing tools and infrastructure—voice infrastructure for access and web infrastructure for content.
Several vendors have implemented this technology. VoiceXML 1.0/2.0 has been adopted by most major players to extend their products to conform to the next versions of additional markup languages/tags from the World Wide Web Consortium, or W3C, the group responsible for the VoiceXML open standard. Thousands of VoiceXMLbased applications have been developed in the last few years. Companies have updated standard offerings such as voice mail as well as newer applications like voice portals, voice-access to e-mail, voice-activated dialing and many more.
VoiceXML offers tremendous opportunities for communications service providers. Among other advantages, VoiceXML allows access to a larger development community for applications and to additional sources of information. To compete in the emerging markets for next-generation voice-activated services, providers must greatly accelerate the pace at which they bring new services to market, and VteliX helps make this possible.
