We’ve reached out to Instagram for comment. We’ll note here not every feature the company works on behind the scenes ends up in a public release. When Instagram introduced private Story likes, it said its motivation was to reduce inbox clutter. Adding the option to send voice messages would run counter to that philosophy, but it would make it easier to do something you can already do within the app. All products recommended by Engadget are selected by our editorial team, independent of our parent company.
