Computer vision encompasses the field of study where machines are trained to interpret and understand visual information from the world, typically in the form of images or video. This includes technologies and methods that enable computers to identify and process objects in images, leading to meaningful analysis and automated responses.

Facial recognition technology utilizes computer vision techniques to identify and verify a person's identity based on their facial features. Optical character recognition also falls under computer vision, as it involves processing images of text and converting them into machine-readable characters. Image classification tasks are directly related to computer vision as well, as they involve categorizing images into predefined classes based on the content they depict.

In contrast, speech recognition pertains to the ability of a machine or computer program to identify and process human speech. This technology focuses on auditory data rather than visual data, making it a foundational component of speech processing rather than computer vision. Therefore, the answer to the question of which choice is not an example of computer vision is indeed speech recognition.
