Interactive task-sensitive assistant
First Claim
1. A machine-executed method of providing interactive assistance for the performance of a set of predefined steps, said method comprising:
- A. accessing data related to the set of predefined steps, and for each of one or more steps from said set of predefined steps, automatically generating a grammar, including;
1) generating a set of navigation commands related to the step, based on a context of the step; and
2) generating a set of rules to recognize potential queries related to the step, based on the context of the step;
B. providing a recognizer configured for determining if a received vocal utterance corresponds to one of said set of generated navigation commands or one of said potential queries related to a current step according to the generated rules, within a context of said current step; and
C. navigating to a different step from the current step if said vocal utterance is a navigation command corresponding to at least one of the generated navigation commands or providing a response if said vocal utterance is a query corresponding to one of said potential queries according to the generated rules.

Abstract
A system and method in accordance with the present invention include means for providing interactive assistance for the performance of a set of predefined steps, including selecting the set of predefined steps and automatically generating a step-sensitive grammar for each step. Generating the step-sensitive grammar includes generating a set of navigation commands related to each step and generating a set of rules to recognize potential queries related to each step. A recognizer is configured for determining if a received utterance forms one of the navigation commands or one of the potential queries, within a context of the current step. Form this determination, provided are navigation to a different step if the utterance was a navigation command or a response if the utterance was a query.

2. A machine-executed method of generating step-sensitive grammars for a recipe, including:
-
A. parsing the recipe into a set of steps; B. selecting a recipe step from the set of steps; and C. generating a grammar comprising a set of rules, including; 1) determining if the recipe step includes an ingredient reference and, if so, adding to said grammar a rule that recognizes the ingredient in a query; 2) determining if the recipe step includes a technique reference and , if so, adding to said grammar a rule that recognizes the technique in said query; 3) determining if the recipe step includes a tool reference and, if so, adding to said grammar a rule that recognizes the tool in said query; and 4) repeating
