Prime Video is rolling out a new accessibility feature called Dialogue Boost, which has initially launched on select Amazon Originals worldwide.

According to the streamer, Dialogue Boost lets susbcribers increase the volume of dialogue relative to background music and effects, creating a more comfortable and accessible viewing experience that cannot be found on any other global streaming service.

Dialogue volume is the latest addition to Prime, where members in the US enjoy savings, convenience, and entertainment, all in a single membership. While Dialogue Boost was built with the needs of customers who are hard of hearing in mind, anyone can use the feature to suit their personal listening preferences, the streamer said in a statement.

“At Prime Video, we are committed to building an inclusive, equitable, and enjoyable streaming experience for all our customers,” said Raf Soltanovich, VP of Technology at Prime Video and Amazon Studios.

“Our library of captioned and audio described content continues to grow, and by leveraging our technological capabilities to create industry-first innovations like Dialogue Boost, we are taking another step to create a more accessible streaming experience,” Soltanovich added.

How Dialogue Boost works? Dialogue Boost analyzes the original audio in a movie or series and intelligently identifies points where dialogue may be hard to hear above background music and effects. Then, speech patterns are isolated and audio is enhanced to make the dialogue clearer.

This AI-based approach delivers a targeted enhancement to portions of spoken dialogue, instead of a general amplification at the center channel in a home theater system. As a result, Dialogue Boost can be enjoyed anywhere the Prime Video experience is available.

How to find Dialogue Boost? During playback, customers can view and choose which level of Dialogue Boost they would like to use via the audio and subtitles drop down menu. The audio tracks are labeled “English Dialogue Boost: Medium” and “English Dialogue Boost: High.”

Dialogue Boost is available across all devices that support the Prime Video experience and offers a capability that was previously only available to customers with high-end theater systems, specialized audio equipment, or select smart TVs.

Customers can now access Dialogue Boost on select Amazon Originals. The feature will become available on additional titles this year.
