How to Dictate a Text Message in S-Voice
To send a text message through the S-Voice app on your Galaxy S6, say the words, “Send a text.” Done. You see the word appear in the S-Voice box at the bottom of the page as seen here.
S-Voice asks you, “Who would you like to message?” Give the name. It looks up their number from your contact list. In the following figure, the name “Ludwig van Beethoven” was said.
S-Voice then asks you for your message. Go ahead and say what you would have typed.
S-Voice then converts your words into a message. It displays what it thinks you said in a box similar to the box shown in this figure.
Read it before you send it. If it is correct, just say “Send” and off it goes. If it’s incorrect, you can say “Cancel,” and it won’t send that message. You can then try again.
