Amazon is making it easier for you to hear their shows and movies — literally.

Starting today, you can fire up select original Prime Video titles on any device that supports Prime Video and enable Dialogue Boost.

The idea of dialogue-boosting audio isn’t exactly new; some high-end home theater systems and soundbars feature technology that allows users to make dialogue more crisp and clear. However, on a more widespread level, Amazon claims to be the first streaming service to offer this technology broadly. While initially designed for people who are hard of hearing, it’s now available to use for all Prime Video subscribers.

Dialogue Boost functions by analyzing a movie or show’s original audio for points where dialogue may be harder to hear for several reasons. It then enhances the audio by isolating the speech, which makes the dialogue clearer. Amazon says this AI-driven approach differs from the speakers and soundbars mentioned earlier because it targets specific phrases rather than amplifying the audio more generally.

Dialogue Boost has three levels: high, medium, and low. You can check the availability of the technology on a specific title by checking out the details page of any show or movie. If available, you can turn it on like you would change the language or turn subtitles on once you’re viewing a title.

Right now, Dialogue Boost is available for the original series The Marvelous Mrs. Maisel, Tom Clancy’s Jack Ryan, Harlem, and movies The Big Sick, Being The Ricardos, and Beautiful Boy. Amazon will be adding support for more titles as the year goes on.

The technology isn’t available on movies purchased or rented or on Prime Video Channels add-ons at this time.

If you’re not already subscribed to Prime, it costs $14.99/month as part of an Amazon Prime membership or $8.99/month if you just want to access Prime Video. All new memberships come with a 30-day free trial.
