DuoListen is a Chrome extension designed to enhance the language learning experience on Duolingo by removing the hint sentence from exercises. This feature aims to increase the difficulty of translation tasks, encouraging users to rely solely on their listening comprehension skills. By eliminating the written prompt, users are prompted to focus on audio inputs, which can potentially accelerate their language acquisition process.

The extension operates seamlessly within the Duolingo interface, activating on the /skill route and detecting when a new exercise has been loaded. Upon identifying an exercise with a hint sentence, DuoListen effectively hides it, thereby challenging users to engage more deeply with the material. This straightforward functionality makes it a practical tool for those looking to improve their language skills through enhanced listening practice.
