According to Amazon, at the time of writing the article, Dialogue Boost is compatible with 'Amazon Originals', which is Amazon's own content. With Dialogue Boost, it is possible to increase the volume of dialogue compared to background music and sound effects, enabling a more comfortable and accessible viewing experience.

By analyzing the voice of the content with AI, Dialogue Boost identifies points where the conversation is particularly difficult to hear, and separates the voice of the dialogue part to make it easier to hear clearly. Amazon said, ``This AI-based approach focuses on the conversation part and emphasizes the voice, unlike the overall increase in sound in the home theater,'' and not only at home but also in the mobile environment Dialogue Boost I hope you can experience

Amazon said, ``Dialogue Boost is built with the needs of hearing-impaired customers in mind, but everyone can use the features to suit their personal listening preferences.'' News site Ars Technica points out that 'Dialogue Boost also responds to widespread complaints among viewers.'

According to Ars Technica, in a survey of 1,260 Americans in 2022 , 50% said they 'watch subtitled content', and many of them said, 'The audio is jumbled and I can't watch movies.' And it's getting harder to understand the lines of TV programs than before.' Ars Technica considered that Dialogue Boost is not only for people with hearing impairments, but also for the tendency of lines to be difficult to hear.

In addition, Amazon says that it will increase the content compatible with Dialogue Boost in the future.
