Amazon Lex provides enhanced confirmation and currency built-in slots to 10 additional languages

Posted on: Sep 18, 2025

Amazon Lex now provides support for confirmation and currency slot types in 10 additional languages: Portuguese, Catalan, French, Italian, German, Spanish, Mandarin, Cantonese, Japanese, and Korean. Built-in slots help you build more natural and efficient conversations by understanding synonyms of what you user says and resolving those inputs to a standard format. The confirmation slot helps understand various expressions of user acknowledgement and converts them into ‘Yes’, ‘No’, “Don’t know’‘, or ‘Maybe’. The currency slot helps identify currency and represents the input in a structured way. For example, when a user says “nope” or “absolutely not”, the confirmation slot resolves to ‘No’ or when the user says “1 dollar’, the currency slot resolves it to ”USD 1.00“. These built-in slots help you build more natural and efficient conversational experiences.
