Voice XML is a programming language used for telephone systems and voice assistants. It is part of a set of markup languages developed by the W3C. VXML helps interpret voice commands and is used for customer service applications. Telecom operators see potential for future functionality.
VXML, or Voice XML, is a type of programming language that helps computers and other devices operate over telephone lines. VXML is part of a set of extensible markup languages. It provides much of the direction for the landline and cell phone programs, including voice commands and voice messaging systems.
Extensible Markup Language, or XML, is a type of coding convention for developing many different types of applications. A similar markup language, HTML, is used to create web pages. Like HTML, Voice XML uses browsers to read the code that programmers write in it.
With Voice XML, much of the code that enters a browser is read as speech communication. When you listen to a personal voice assistant, an automated telephone service, the words you speak may have been programmed into a VXML code module. VXML also helps the service interpret what you say and respond appropriately.
Voice XML often passes over the PSTN, or public switched telephone network, to allow all landline and mobile phone customers to use the applications built with it. Many of these applications handle telephone customer service for a variety of businesses. More and more companies across all industries are relying on this type of applications to interact with their customers.
Voice XML and other XML languages, along with HTML, are part of a set of languages developed by the W3C, or World Wide Web Consortium. The W3C is an organization that helps provide standards for all types of coding, to help the international developer community avoid problems arising from diversity in coding and programming styles. The W3C is active in promoting the use of XML-like languages, including VXML. It does a lot of behind-the-scenes work to bring modern features to the IT field for browser-based setups.
Although Voice XML is standardized, companies use a variety of browsers to access a VXML platform. W3C continues to produce versions of Voice XML for use on these channels. In addition to what is currently offered, major telecom operators recognize the great potential of voice command and other VXML technologies, for even greater functionality in the future. Other independent non-profit groups help monitor the growth of telephone automation and look for ways to make it more effective and efficient with the latest technology on the market. Any business with additional customer communications needs can look into a wide variety of VXML-based products and services to set up a more robust telecommunications presence for customers anywhere in the world.
