Conversational AI enables machines to understand, interpret, and respond to human language, in a meaningful and contextually relevant way. It uses technologies like speech recognition, natural language understanding, and text-to-speech conversion to translate spoken language into text, comprehend the meaning and intent of the speaker, and turn the output back into audible speech.
