Voice recognition with AWS Lex

Voice recognition is the ability of a machine or software to identify and process spoken words or phrases. Voice recognition can be used to create conversational interfaces that allow users to interact with applications using natural language. One of the services that enables voice recognition is AWS Lex, a fully managed artificial intelligence (AI) service that lets you build chatbots with conversational AI.

AWS Lex uses advanced natural language models to design, build, test, and deploy conversational interfaces in applications. You can use AWS Lex to create virtual agents and voice assistants, automate informational responses, improve productivity with application bots, and maximize the information trapped in transcripts.

To use AWS Lex, you start by designing your conversation in the Lex Console, providing Lex with some sample phrases that are used to build a natural language model. Then you publish your Amazon Lex bot and let it process text or voice conversations with your users. AWS Lex uses automatic speech recognition (ASR) to transcribe the user's request before it is interpreted by natural language understanding (NLU). AWS Lex also provides confidence scores for each transcription and slot value inferred from the user input, which can help you resolve ambiguity and improve accuracy.

AWS Lex is a fully-managed service so you don't need to spend time setting up or maintaining any infrastructure. You can also connect seamlessly with other AWS services to query data, execute business logic, monitor performance, and more. You only pay for speech and text requests with no upfront costs or minimum fees.
