I used to do mechanical turk jobs for some quick and easy pocket money. There were several types of tasks you could do, and there was a sort of ranking system to dissuade anyone from just inputting junk instead of answering seriously. I usually stuck to surveys and things I would describe as fancy captchas. I recall a few jobs where the task was to record yourself in different environments reading the same script of text. I can’t see that type of job for being anything other than training data for AI/ML
