Summarize this content to 2000 words in 6 paragraphs One of the most frequent complaints about watching movies and shows on your TV at home is that dialogue is muddied, faint or can’t compete with the bombast coming from everything else on the screen. The problem has gotten so bad that companies are putting out products specifically to deal with it, such as soundbars that boost dialogue and TV audio settings that enhance audio frequencies where dialogue usually appears. It’s now even common practice in many homes to turn on subtitles and leave them on.Last year, Apple added a feature called Enhance Dialogue to Apple TV that works when paired with a second-generation HomePod. In iOS 18, iPadOS 18 and tvOS 18 coming this fall — and available in beta right now — the feature works more broadly, with your device’s speakers or any connected Bluetooth buds and headsets.Read more: How To Download iOS 18 Public Beta 3 on Your iPhoneOne downside to this expansion of Enhance Dialogue is that so far in the betas, the feature appears only in Apple’s TV app on iPhone, iPad and Apple TV. Hopefully developers such as Netflix, Disney, MAX and the other major streamers will be able to add support for it when the system updates launch in the fall. Also, for the Apple TV, the feature is limited to the Apple TV 4K (2nd generation) and later models. Here’s everything you need to know. Apple 4K TV Apple/CNETHow does Enhance Dialogue work?Plenty of factors contribute to dialogue becoming unintelligible. When audio engineers mix the sound for a movie, they’re often targeting how it will play in a movie theater — and even there the variety of audio hardware and acoustics is all over the place. Mixing for the home can be even more tricky, trying to accommodate setups pushing sound from mediocre television speakers as well as through elaborate home theater systems. Then take all that data and squeeze it through compressed streaming channels, and now you’re far away from the engineers’ intentions.Enhance Dialogue uses machine learning to differentiate between spoken words and other sounds and has two modes. Enhance raises the levels of dialogue without affecting other audio as much. Boost dampens the background in a more aggressive way and also enhances the dialogue to make it stand out — the effect is most apparent in scenes with a lot of competing noise.This easily overlooked feature will help you discern what’s being said on your device or TV so you don’t miss any nuance that would otherwise be drowned out by other noise.How to enhance dialogue on iPhone and iPadBefore we start, you do need to be running iOS 18, which is currently available to download as a developer beta and a public beta — we suggest downloading the latter if you want a more stable version of iOS 18.Now, on iOS 18 or iPadOS 18, open the TV app and start playing a movie or TV show.To turn on Enhance Dialog, do the following:Tap the screen to reveal the playback controls.Tap the Audio Options button (which looks like a waveform inside a circle). If you’re viewing the video in portrait orientation, tap the More (…) button and tap Audio.Expand the Enhance Dialogue menu and choose either Enhance or Boost. Turn on Enhanced Dialogue in the TV app under iOS 18. (The video is blacked out when taking screenshots due to the iPhone’s built-in copyright protection.)

You can also set an Enhance Dialogue preference in the Apple TV settings. Go to Settings > Video and Audio > Enhance Dialogue and choose either Enhance or Boost. On the Apple TV in tvOS 18, Enhance Dialogue is a system-wide setting, even if so far the feature appears to apply only to videos played in the TV app. Screenshot by Jeff Carlson/CNET
