Avaya Voice Browser overview

Last Updated : Jun 05, 2026 |

A voice browser is a web browser that presents an interactive voice user interface to the user. In addition, it typically provides an interface to the PSTN or a PBX. Just as a visual web browser works with HTML pages, a voice browser operates on pages that specify voice dialogues. These pages are usually written in VoiceXML, but other proprietary voice dialogue languages remain in use.

TheAvaya Voice Browser is a VoiceXML interpreter. The Avaya Voice Browser performs the following functions:

  • Fetches VoiceXML and ECMA script documents.

  • Parses, translates, and stores VoiceXML documents. Stores parsed VoiceXML pages in memory.

  • Loads and switches Execution context.

  • Loads, activates, and unloads Grammars. Supports SRGS 1.0 and simple JSGF 1.0.

  • Browses through VoiceXML elements and interprets them.

  • Translates <Prompt> elements to SSML 1.0 format and collects user inputs.

  • Reports events (throws exceptions) according to VoiceXML specification.
