Applications using speech recognition are becoming more popular. Among different methods to perform speech recognition, applications using speaker-independent predefined grammars are being widely used. One of the key components of a speech recognition application are the dialogs (interface between the human and the application). A dialog is a sequence of prompts and input based on predefined grammars. Grammars can range from simple words to complex phrases. For instance, an application asking for a date will need a grammar able to handle different ways of speaking a date. Using March 1st, 2000 as example, here is a (non-complete) list of possible ways of saying this date: zero three zero one two thousand; march the first two thousand; first of march in two thousand; three one zero zero; three one double zero; three one double oh How the grammar's developer can exercise the grammar to make sure it is working as designed, without the real application? Disclosed is a grammar test tool for providing an easy way to test a set of speaker-independent predefined grammars created to be used in a voice application.
