Greg Bulmash from Amazon spoke at OSCON 2017 Conference last week about developing your own virtual assistant applications using Amazon’s Lex and Polly technologies. He talked about how to plan and execute voice interfaces for these browser-based “Do it Yourself Virtual Assistant” (DIYVA) applications that listen and respond in natural language. They are based on Alexa’s voice recognition, Artificial Intelligence (AI), and speech synthesis technologies.
Amazon Lex is used for building conversational interfaces into applications using voice and text. It provides the 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.
