The voice mode grammar library contains a collection of preconstructed grammar rulesets. Each ruleset contains a number of publicly scoped rules that are designed to recognize spoken input for a specific type of data such as a date, time, or numbers. Click the links in the table to read documentation describing the syntax and return values for the rules contained in each of the rulesets.
The voice mode grammar library is provided as a convenience, obviating the need for developers to write their own rules for collecting commonly used data and enabling developers to easily develop more complex grammars based on these types of common data. In addition, many of the individual rules provide built-in validation. For example, if a developer activates the DigitBlock_2Digits rule, the user must provide the correct number of digits (two) required for that rule.
