Amazon Prime Video just made dialogue easier to hear with this new feature

Now, on Amazon's Prime Video, you can clearly hear what all the characters are saying


We've all been there. You get the best HD TV possible for a beautiful, lifelike viewing experience, but the dialogue sounds muffled and pushed to the background. To compensate, you inch up that volume. It starts with a few clicks, but you keep raising the level until even the quiet conversations are easy to hear. Then the music comes on, and it 's so loud, your car alarm goes off due to the vibrations.

Now, on Amazon's Prime Video, there's another way. It is called Dialogue Boost, and it is built right into the streaming service, so you don't need to buy any additional equipment to take advantage of this technology.

How does Dialogue Boost work?

Dialogue Boost originally was intended for viewers with specific listening needs, but it can be used by anyone. This AI-based feature identifies sections in the soundtrack where sound effects, music and other audio might bury the dialogue. Instead of raising the volume of a specific channel, it isolates and amplifies just the dialogue, no matter where it sits in the mix, so everything the characters are saying is easier to hear.

Where do I find Amazon's Dialogue Boost?

Amazon's Dialogue Boost is located in the audio and subtitles drop-down menu on your device. This menu will let you know if the feature is available for the content. It will also give you two options: “English Dialogue Boost: Medium” and “English Dialogue Boost: High.” This way, you can set the Dialogue Boost to your needs.
