Dialogue Boost is Prime Video’s exclusive audio enhancement feature that allows viewers to increase dialogue volume relative to background music and effects. This premium capability works seamlessly across all Prime Video-supported devices without requiring specialized equipment, bringing theatre-quality audio control directly to your audience. While designed with hard-of-hearing audiences in mind, Dialogue Boost serves diverse viewing preferences including viewers in noisy environments, late-night viewing with reduced volume, and content with complex dialogue or challenging accents.
Dialogue Boost ensures your storytelling reaches audiences clearly and effectively, reducing reliance on closed captions so viewers can focus on the visual artistry of your content while comprehending every word. The feature is automatically created for eligible titles through Prime Video’s advanced audio processing with no additional deliverables or technical specifications required from partners. Viewers discover Dialogue Boost availability on your title’s detail page and can activate it through the in-player audio menu, choosing between Medium or High enhancement levels to personalize their experience.
