Natural language processing (NLP) significantly aids in communication by enabling computers to understand, interpret, and generate human language. It bridges the gap between humans and machines, allowing for more natural interactions through applications such as chatbots, virtual assistants, and language translation services. NLP techniques, like sentiment analysis and named entity recognition, help extract meaningful information from textual data. By enhancing human-computer interaction, NLP facilitates better customer service, improves accessibility, and streamlines various communication processes in diverse sectors, including healthcare and finance.
