OK, so I have an iPhone, with Dragon installed. I can use it from the Dragon app, and send the message as a txt. But is there a way to start from the Messages Icon and engage the Dragon software to txt people without having to type?
Like the poster above said, you can't. Dragon is an outside app. You can only use it within the app and then cut and paste to your message. I have noticed though that Dragon is more accurate with voice to text than Siri is.
