System and method for parameterization of speech recognition grammar specification (SRGS) grammars

A system comprising:

• a processor;
• and
• memory having instructions stored thereon that, when executed by the processor, cause the processor to automatically recognize speech matching grammars in audio by:
• loading a grammar specification defining at least one parameterizable grammar, the at least one parameterizable grammar corresponding to a type of speech input and the at least one parameterizable grammar comprising a plurality of rules defining constraints on speech corresponding to the type of speech input;
• setting an initial state of a grammar processor as a current state, the current state comprising parameters supplied to the rules;
• selecting a rule of the plurality of rules matching the parameters of the current state of the grammar processor;
• applying the selected rule to the audio and updating the current state to compute an updated state comprising a plurality of updated parameters;
• determining whether termination conditions have been met;
• in response to determining the termination conditions are not met, selecting from the plurality of rules in accordance with the updated parameters of the updated state;
• and
• in response to determining the termination conditions are met, outputting a recognizer result of the updated state.
