Multimodal Web-based Dialogue: XHTML + Voice and SALT

  • Michael F. McTear

Abstract

VoiceXML was designed with telephone-based interaction in mind. VoiceXML supports recognition of spoken and Dual Tone Multiple Frequency (DTMF) input, output of synthesised and recorded prompts, and interaction with back-end applications on the web. An extension to VoiceXML supports multimodal interaction with web-based applications on devices such as advanced mobile (cellular) phones and Personal Digital Assistants (PDAs). This extension,known as XHTML + Voice, allows developers to speech-enable visual web pages by incorporating and linking VoiceXML code with the visual markup code written in XHTML. An alternative to XHTML + Voice is SALT (Speech Application Language Tags). SALT is a set of extensions that add speech recognition, speech synthesis, and telephony capabilities to existing markup languages, such as HTML and XHTML, to enable multimodal and telephony access to web-based applications from PCs, telephones, tablet PCs and wireless PDAs.
