AMAZON.FirstName

Commonly used first names. This slot type recognizes formal names, informal nicknames, and names consisting of more than one word. The name sent to your intent is the value sent by the user. Amazon Lex V2 doesn't convert from the nickname to the formal name.

For first names that sound alike but are spelled differently, Amazon Lex V2 sends your intent a single common form.

The AMAZON.FirstName slot type supports inputs using spelling styles. You can use the spell-by-letter and spell-by-word styles to help your customers enter names. For more information, see Capturing slot values with spelling styles during the conversation.

Examples:

AMAZON.FirstName also returns a list of closely related names based on the original value. You can use the list of resolved values to recover from typos, confirm the name with the user, or perform a database look-up for valid names in your user directory.

For example, the input "John" may result in returning additional related names such as "John J" and "John-Paul".
