Speak & Translate allows you not only translate the speech or text but also to share the Translation in a couple different ways.
To see available options - tap the translated text. This will bring up 5 buttons.
Buttons 1-4 allows you to perform various actions with your translated text:
1 - pronounces translated word or phrase. This will only work if the language you chose is supported in the Speech to Speech translation.
2 - copies the translated text to the clipboard and allows you then to paste it in a different app or message.
3 - this button creates a new message that will contain the translated text and all you will have to do is to set the recipient of a message and then tap Send.
4 - opens a menu in which you can choose the way to share translated text (Mail, Twitter, Facebook, etc.)
