The technology used for voice and natural language processing includes machine learning algorithms, neural networks, and specialized frameworks like speech recognition software. These technologies enable systems to understand, interpret, and generate human language, making interactions with devices more intuitive. Voice recognition allows for hands-free operation and voice commands, while natural language processing analyzes text to derive meaning and context, facilitating tasks such as sentiment analysis or automated customer support. Together, these technologies are integral to developing applications such as virtual assistants and chatbots, enhancing user experience in various sectors.
