Twitter may have doubled the length of tweets in 2017, but sometimes even the 280 characters δεν αρκούν να μεταφέρουν το μήνυμά σας. Τώρα, το Twitter προσθέτει άλλο ένα feature which will allow you to voice tweets.
This feature is currently exclusive to iOS devices and allows you to post voice messages to your tweets like voice clips on WhatsApp or other sharing services messages. 
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 in your timeline with a large card like a video tweet. The sound does not play automatically. You need to click on the image to start.
