Smart Pause is designed to help you practice listening in complete sentences. When you encounter a new word and hit pause, playback continues until the end of the sentence. You will be able to see the definitions of our curated vocabulary within the full context of the sentence.
In the real world it would be strange to cut someone off mid-sentence. Our Smart Pause feature encourages listening to complete sentences instead of broken fragments. When you practice listening in your target language, it should feel like natural listening.
And if you prefer a more traditional pause behavior, just turn it off in the new Settings panel, accessible at the top right of the player screen.
