It is very important that you listen to the language as much as possible. You can listen to Sanskrit news or find some good videos in the Sanskrit language online. Though a passive activity, listening not only helps in understanding the pronunciation but also allows you to understand how sentences are formed and used in regular conversations thus enabling you to speak Sanskrit effortlessly.
