Amazon Prime Video has introduced a new feature called Dialogue Boost, which allows viewers to increase the volume of dialogue relative to background music and effects. The feature is initially designed for Prime Video customers who are hard of hearing, but can be used by anyone to suit their personal listening preferences.

Dialogue Boost is now available worldwide on select English-language Amazon originals, including The Marvelous Mrs. Maisel, Tom Clancy's Jack Ryan, and Harlem, as well as films like The Big Sick, Being the Ricardos, and Beautiful Boy. Amazon has also announced plans to add Dialogue Boost support for additional titles later this year.
