Grammar Format

The Vestec Speech Engine supports industry standard grammar writing format, including SRGS syntax and SISR tags.

SRGS (Speech Recognition Grammar Specification)

The W3C defined the SRGS syntax to represent speech recognition grammars. The syntax of the grammar format is presented in two forms, an ABNF Form and an XML Form. ABNF is by far the more popular of the two formats on account of its simplicity and intuitiveness.

SISR (Speech Interpretation for Speech Recognition)

The W3C defined SISR tags to facilitate interpretation of complex speech recognitions. SISR tags enable embedding of snippets of JavaScript code into SRGS grammars to automatically transform a speaker’s utterance into a format understandable by an application.
