I would love to see a real-time speaking feedback tool that not only scores the response but also gives live voice coaching. For example, after I say my "Read Aloud" or "Describe Image" response, the system should highlight mispronunciations, fluency issues, and grammar errors — and show how to fix them with voice samples. This would help students speak more clearly and confidently — especially non-native speakers who struggle with pronunciation and pauses. Adding this feature with voice comparison to native-like samples and auto replay correction would be a game-changer.
