One short conversation at a time
A Voice Mission is a single real moment: ordering a coffee, checking into a hotel, asking which exit is open. Most take two or three minutes.
How TUD works
How TUD works: you speak, TUD answers, help stays on screen.
TUD is a speaking app. You tap a place on a city map and a character talks to you in the language you are learning. You answer out loud. The help you need is always on your screen, not something you ask the character for.
Plain answer
TUD talks to you in your new language. Your help is on the screen.
This is the part that surprises most new learners. The character you speak with stays in your learning language for the whole mission, because that is the practice. When you get stuck you do not ask the character for a translation. You read the coach card on your screen, which shows you what to say.
How it helps
Built for useful speaking practice.
TUD stays in your learning language
The character will not switch to English. That is deliberate, not a fault. Listening and answering in the language you are learning is the whole exercise.
The coach card is your help
Guided shows a full example sentence you can read out loud, Balanced shows the key words, and Immersive shows nothing when you want the challenge.
Objectives turn into XP
Each mission has a few goals. They tick off as you speak, and completed goals earn the XP that unlocks new areas of the city.
Step by step
What happens in a mission.
Every Voice Mission follows the same shape, so once you have finished one you know how all of them work.
- Tap a place on the city map and choose a mission.
- Pick how much help you want: Guided, Balanced, or Immersive.
- The character speaks first, in the language you are learning.
- Answer out loud. Your goals tick off as you complete them.
- At the end you get a short review of what went well and what to try again.
When you are stuck
Read the card instead of asking for a translation.
New learners often try to ask the character for help in their own language. The character stays in the scene and keeps speaking your learning language, so the conversation can stall. The coach card is where the answer lives.
- Look at the coach card on screen for the sentence or the key words.
- Choose Guided before you start if you want a full example sentence every time.
- A rough attempt in your learning language still counts. Trying it in the language matters more than perfect grammar.
- Missions can be failed, and you can replay any mission as often as you like.
Progress
Speaking time, XP, and levels.
TUD is free to use every day, and the harder levels are earned rather than bought.
- Free learners get 10 speaking minutes per day, and 5 minutes of speaking keeps your daily streak.
- Completed goals earn XP, and XP unlocks the CEFR-style A1-C2 path.
- TUD Pro adds unlimited speaking time, no ads, and early access to B1-C2.

FAQ
Common questions.
Why does TUD only speak the language I am learning?
Because that is the practice. A Voice Mission is a roleplay, and the character stays in your learning language the whole way through so you get used to listening and answering in it. Your own language is still used for the app itself and for the help on screen.
How do I get help in the middle of a mission?
Read the coach card on your screen. In Guided it shows a full example sentence you can say out loud, and in Balanced it shows the key words. Asking the character for a translation will not work, because the character stays in the scene.
What are Guided, Balanced, and Immersive?
They are the three support levels you can choose before a mission starts. Guided gives you an example sentence for every goal, Balanced gives you key words, and Immersive gives you no on-screen help at all. You can change it for each mission.
Can I fail a mission?
Yes, and that is fine. A goal you do not manage simply earns no XP. You still get a short review at the end, and you can replay any mission as many times as you want.
How much speaking time is free?
Free learners get 10 speaking minutes per day, and speaking for 5 minutes keeps your daily streak. TUD Pro adds unlimited speaking time.
How do I unlock new parts of the city?
By earning XP from completed mission goals. Free learners can unlock the whole CEFR-style A1-C2 path with XP. TUD Pro gives early access to B1-C2, but it is not required to reach them.
