Twitter may have doubled the length of tweets in 2017, but sometimes even 280 characters are not enough to convey your message. Now, Twitter is adding another feature that will allow you to have voice tweets.
This feature is currently exclusive to iOS devices and allows you to publish voice messages στα tweets σας, όπως τα κλιπ φωνής στο WhatsApp ή σε άλλες services messaging.
To use this mode, just tap the compose a new Tweet button and then tap the new sound button that appears at the bottom left. Tap the button and then tap “Done” when you're done.

Voice clips are limited to 140 seconds. However, if you exceed the limit, Twitter automatically launches a new voice tweet and creates a new thread.
Voice tweets appear on your timeline with a large card like one video tweet. THE sound does not play automatically. You have to tap the image to start.
