Voice Mode Grammar Library for Spanish (United States)
.jpg) |
The voice mode grammar library contains a collection of preconstructed grammar rulesets. Each ruleset is designed to recognize spoken input for a specific type of data such as a date, time, or credit card number. Follow 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 or error handling. For instance, if a developer designates the CreditCard ruleset and activates the CreditCardNumber rule, the user must provide the correct number of digits required for that type of credit card; if the user provides either too many or too few digits, the recognition engine returns an InvalidCardNumber node in the Semantic Markup Language (SML) output.
