🤖 Chatbot
💬 A chatbot is a computer program designed to simulate conversation with human users, especially over the internet. Chatbots can range from simple rule-based systems that follow pre-programmed responses to sophisticated artificial intelligence (AI) models capable of understanding natural language and engaging in more complex interactions. They are used in various applications, including customer service, virtual assistants, information retrieval, and entertainment.
👨💻 Amazon Lex
📌Amazon Lex is a service provided by Amazon Web Services (AWS) that enables developers to build conversational interfaces, or chatbots, into their applications using voice and text. It utilizes the same technology that powers Amazon Alexa, the virtual assistant found in Amazon Echo devices.
📌With Amazon Lex, developers can create natural language understanding (NLU) models that interpret user input and respond accordingly. Lex handles the heavy lifting of speech recognition and natural language understanding, allowing developers to focus on designing conversational flows and integrating the chatbot into their applications. It can be integrated with other AWS services, such as AWS Lambda for executing backend logic, Amazon DynamoDB for data storage, and Amazon Polly for text-to-speech synthesis
