Human: What is the difference between voice recognition and voice activation? Assistant: 
The main difference between voice recognition and voice activation is that voice recognition is the process of recognizing and understanding words that are spoken, while voice activation is a process that involves responding to a spoken phrase by activating a function, such as a command or search. Voice recognition focuses chiefly on speech recognition, including recognizing words, phrases, accents, and intonations; while voice activation focuses on responding to an utterance with a corresponding action.
