Amazon Lex launches support for Confirmation and Alphanumeric slot types for Korean

Amazon Lex now supports Confirmation and Alphanumeric slot types in Korean (ko-KR) locale. These built-in slot types help developers build more natural and efficient conversational experiences in Korean language applications. The Confirmation slot type automatically resolves various Korean expressions into 'Yes', 'No', 'Maybe', and 'Don't know' values, eliminating the need for custom slots with multiple synonyms. The Alphanumeric slot type enables capturing combinations of letters and numbers, with support for regular expressions to validate specific formats, making it easier to collect structured data like identification numbers or reference codes. Korean support for these slot types is available in all AWS regions where Amazon Lex V2 operates. To learn more about implementing these features, visit the Amazon Lex documentation for [Custom Vocabulary](https://docs.aws.amazon.com/lexv2/latest/dg/vocab.html) and [Alphanumerics](https://docs.aws.amazon.com/lexv2/latest/dg/built-in-slot-alphanumeric.html).
