After showing off the gaming and Continuity features of the iPhone 6 and iPhone 6 Plus in a couple of new ads featuring voice overs from Justin Timberlake and Jimmy Fallon earlier this week, Apple on Wednesday released one more similar commercial, the seventh in the series, which highlights a different feature, voice texting, which is available on iOS 8-compatible devices.

In addition to regular iMessage texting, voice text lets users record short messages and send them to their friends and family. As Timberlake and Fallon explain it, the feature is really useful for highlighting sarcasm, singing a message, or avoiding really tough-to-spell words — though on the latter, Apple’s iOS 8 also comes with a smarter default keyboard that can deal with such words.

The 30-second “Voice Text” ad follows below and some other Timberlake and Fallon iPhone 6 ads, which Apple calls “films,” are available on a special page on Apple’s site.
