RLHF vs TTS
RLHF (Reinforcement Learning from Human Feedback) and TTS (Text-to-Speech) both come up in ai & ml conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: RLHF refers to reinforcement learning from human feedback, while TTS refers to text-to-speech — they describe different things even when they show up in the same sentence.
RLHF — Reinforcement Learning from Human Feedback
A training technique where humans rank or score AI outputs, and that feedback is used to fine-tune the model. RLHF is what made ChatGPT useful rather than just smart.
TTS — Text-to-Speech
AI technology that converts written text into spoken audio. Modern TTS produces near-human voices in dozens of languages.
