Starting today, Amazon Lex  is available in the Asia Pacific (Seoul) and Africa (Cape Town) regions. Amazon Lex is a service for building conversational interfaces into any application using voice and text. Amazon Lex combines advanced deep learning functionalities of automatic speech recognition (ASR) for converting speech to text, and natural language understanding (NLU) to recognize the intent of the text. This enables you to build applications with engaging users experiences and lifelike interactions. With Amazon Lex, you can easily create sophisticated, natural language, conversational bots (“chatbots”), virtual agents and IVR systems.

Starting today, you can use EC2 Fleet with targeted On-Demand Capacity Reservations. On-Demand Capacity Reservations enable you to reserve compute capacity for your Amazon EC2 instances in a specific Availability Zone for any duration. For targeted Capacity Reservations, instances must specifically target the Capacity Reservation to run in the reserved capacity. Until now, there was no option to use targeted Capacity Reservations when launching an EC2 Fleet.

Today we are launching Audit One-Click for AWS IoT Device Defender . Audit One-Click makes it easy for AWS IoT Core customers to improve their security baseline by making it possible to start auditing their account and IoT devices against security best practices with a single click.

You now can use AWS CloudTrail to filter and retrieve Amazon DynamoDB Streams data-plane API activity, giving you more granular control over which DynamoDB API calls you want to selectively log and pay for in CloudTrail and to help address compliance and auditing requirements.

Amazon Lex is a service for building conversational interfaces into any application using voice and text. Starting today, Amazon Lex makes utterances statistics available through the Amazon Lex V2 console and API. You can now use utterances statistics to tune bots built on Lex V2 console and APIs to further improve conversational experience for your users. With this launch, you can view and analyze utterance information processed by the bot. This information can be used to improve performance of your bot by adding new utterances to existing intents and helping you discover new intents that can be serviced by the bot. Utterances statistics also enable you to compare performance across multiple versions of a bot.

AWS WAF extends its regular expression (regex) support, allowing regex patterns to be expressed in-line within a rule statement. Previously, you had to create a regex pattern set, which provides a collection of regex patterns in a rule statement, even if you wanted to use just a single regex pattern in your WAF rule logic. With in-line regex, you can now include a single regex pattern directly inside a WAF rule statement, simplifying how WAF rules are expressed within your web ACL.
