Voice text is our latest technology, Today's all voices companies are working on to make their product user friendly.I didn't face this error Galaxy S5, I played Google voice search it several time not worked fine.
So, I'm confused.... you didn't face this error but when you tried it with Google Voice it didn't work? So you did face the error? haha
Again, I just tried Google's Voice-To-Text on three devices and they all work with 'New Line' or 'New Paragraph'. BUT we're all using Google's service. If you're using Samsung's, for instance, that might not work.
I like Google's because now you don't have to select the language, it automagically picks it up for you when you speak, and me usually replying to e-mails in at least English and Spanish, this is VERY handy.
