Which Amazon service allows you to create a chatbot for Interactive Voice Response (IVR)?

Amazon Lex is the service that allows you to create a chatbot for Interactive Voice Response (IVR) applications. It is designed for building conversational interfaces using voice and text. Lex leverages automatic speech recognition (ASR) to convert speech to text, as well as natural language understanding (NLU) to comprehend the intent of the text input. This makes it ideal for creating chatbots that can handle natural language interactions, such as those used in IVR systems.

With Amazon Lex, you can design a chatbot that can process spoken language input from users, enabling a seamless interaction where customers can communicate their needs verbally. The integration capabilities with other AWS services, such as Amazon Connect, enhance the functionality of IVR systems, allowing developers to create more sophisticated and user-friendly voice applications.

Amazon Connect is a cloud-based contact center service that could utilize Amazon Lex for creating IVR systems, but it is not a direct service for building chatbots. Amazon Comprehend is a natural language processing (NLP) service used for text analytics,
