Our Take

Google just dropped a text-to-speech API and the hook is telling it what you want in plain English like it's a human — no tweaking pitch, speed, or random phoneme strings like you're trying to crack a safe. That's genuinely the move, but knowing Google it'll work fine and also somehow feel a little sterile. Would actually test this before I crown it the new standard.
