Dia is an AI language tutor you talk to out loud. Speak from your first conversation, see a better way to say it when you slip, and call Dia when you want live speaking practice. PRACTICE SPEAKING, OUT LOUD Tap the mic and talk. Dia answers in the language you're learning, keeps the conversation going with follow-up questions, and can help in your language when you say you can't follow. Choose how Dia speaks to you: Easy, Standard or Native. CALL YOUR TUTOR Start a voice call and talk in real time, like a phone call. Follow along with captions you can show or hide, ask questions, and rehearse the conversations you want to have in real life. LEARN FROM YOUR MISTAKES Dia points out slips in chat, shows a better way to say it and explains why in a short note. Then the conversation keeps going. Words and phrases you look up are saved for review and start coming back the next day: say each one out loud, then check. CUSTOMIZE YOUR OWN TUTOR Find a tutor you click with. Pick a look and a name from hundreds of options, choose a voice, and edit your tutor any time. UNDERSTAND EVERY REPLY Read translations and tips in your app language, and turn on romanization such as pinyin or romaja in tips. Long-press a reply to copy it or ask about that line. With Premium, Dia reads replies out loud, so you can listen as you read or switch to voice only for listening practice. PRACTICE REAL-LIFE SITUATIONS Order at a café or restaurant, check in at a hotel, take a phone call or chat on a plane. Getting ready for a B1 or B2 speaking exam, a move abroad or a job interview? Describe your own scenario and practice it with Dia. It's conversation practice, not an official mock exam. PRACTICE YOUR TARGET LANGUAGE Choose from 42 language and regional options across 28 languages, including English (US, UK, Australia, Ireland, New Zealand), Spanish (Spain, Mexico, Argentina, Colombia), French (France, Canada), German (Germany, Austria, Switzerland), Portuguese (Brazil, Portugal), Chinese (Mainland, Taiwan), Japanese, Korean, Italian, Arabic and more. Not sure of your level? Take the free level check from A1 to C2 in English, Spanish, French, Japanese, Korean or Chinese. PICK UP WHERE YOU LEFT OFF Continue your last chat from the home screen, revisit your word bank, and see how many words and phrases are saved and when the next review is due. In later chats and calls, Dia can bring back goals and interests you've mentioned. LANGUAGE GUIDEBOOKS Explore writing systems, sounds, sentence patterns and short practice activities for the language you're learning. Guidebook progress is saved to your account. Listening examples use a voice available on your device. Designed for adult learners. A free account is required for chat and includes 10 messages and 2 call minutes a day. Premium removes the daily message limit, reads Dia's replies out loud and includes 10 call minutes a day. New accounts start with 24 hours of Premium, including 10 call minutes in total. It does not turn into a paid plan. Guidebooks are free on every plan. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://talktodia.com/privacy
