Voice assistant for iPhone in Czech, Slovak, Polish and English language. Use your voice for tasks that you could only dictate to Siri in English or German but not in Eastern European languages right now. Dictate SMS, dial contacts and phone numbers, schedule meetings in your calendar, write reminders and items in your shopping list, use speaking calculator or control your smart home via your own Shortcuts and commands such as "turn on the light". Phone • SMS • Shopping list • Calculator • Calendar • Reminders • Shortcuts • Dictate addresses for navigation to Apple Maps, Google Maps, Mapy.cz or Waze • Radio • Name days • Safari • Internet • Jokes Some functions require the iOS application Shortcuts and the shortcut 'Hello Emma Supershortcuts', which you can download directly in the application: Alarm • Timer • Voice recorder • Intercom • Shazam • calling and sending SMS without the need for confirmation on the display. 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.
