"Sometimes 280 characters aren't enough and some conversational nuances are lost in translation," wrote Twitter product designer Maya Patterson and senior software engineer Rémy Bourgoin in a blog post. "So starting today, we're testing a new feature that will add a more human touch to the way we use Twitter -- your very own voice."
Voice tweets look similar to a video in your timeline. It even plays in a box like a video. But instead of seeing a full video, you'll see the person's profile picture surrounded by pulsing circles.
To use the new feature, you can open the tweet composer and press the new wavelength icon to record what you want to say.
Each voice tweet can record up to 140 seconds of audio, the company said Wednesday. Recordings that go longer will automatically create a thread of voice recordings to post.
Voice tweets are now available for a limited group on Twitter for iOS, the company said. Twitter plans to make the feature available to all iOS users in the coming weeks, and anyone can see and hear them in their Twitter timeline.
