If the iPhone misunderstands the dictated text or name or wrongly pronounce something, you can write the correct text in the 'Text Replacement' dictionary and the next time the text will be automatically corrected. I'd love to hear feedback on what Hello Emma still needs to learn. Looking for beta tester for other languages.
