Reinforcement learning from human feedback (RLHF) as you have described here is pretty common in voice recognition.[1] I don't have any inside scoop but I'd be very surprised if there isn't any RLHF going on in these applications. edit to add: The whisper paper mentions using RLHF as a possible path to improve accuracy[2] [1] https://link.springer.com/article/10.1007/s10462-022-10224-2 https://link.springer.com/article/10.1007/s10462-022-10224-2 gives many examples [2] https://cdn.openai.com/papers/whisper.pdf https://cdn.openai.com/papers/whisper.pdf
