Which of the following is NOT an example of artificial intelligence?

Manual data entry does not involve any artificial intelligence processes. It is a straightforward task that relies on human effort to input data into systems without the application of algorithms, machine learning, or decision-making capabilities that characterize AI functions.

In contrast, facial recognition leverages algorithms to analyze and identify faces in images or videos, understanding speech utilizes natural language processing and machine learning to interpret spoken language, and making recommendations often employs collaborative filtering or other AI techniques to suggest products or content based on user behaviors. Each of these examples shows the ability of systems to learn, adapt, or mimic human-like intelligence, which is not the case with manual data entry.
