Translation and travel with AI – from the menu to the itinerary

Three ways to translate: text, image and speech

Translation services have been around for years, but AI has made them far better. Today's tools grasp what a sentence means rather than swapping words one by one. In everyday life you will usually need three kinds of translation:

• Text – for example an email to your landlord in Spain or an instruction manual in German.
• Images – a menu, a sign, a medicine package or a ticket machine. Point your camera and the translation appears on screen.
• Speech – you speak in your language, the phone says the same thing in Spanish, and back again.

Free tools exist for all of these, and most of them work right on an ordinary smartphone.

DeepL or Google Translate: which and when?

DeepL is known for natural, fluent translations, especially between European languages. It is a good choice for longer texts such as letters or documents when you want the result to sound natural. For some languages you can even choose a formal or informal tone.

Google Translate supports a huge number of languages, including less common ones. Its strength is versatility: besides text it handles speech, conversations and camera images. In the phone app you can download language packs in advance so the basics work without an internet connection – handy in a mountain village or on a plane.

Chat-style AI assistants such as ChatGPT and Gemini also translate well. Their advantage is that you can ask for an explanation at the same time: "Why is this word used here?" or "Is this a polite way to say it?"

If you live in Finland, these tools are also a lifeline for Finnish itself – a famously tricky language. A letter from the municipality or a notice in the stairwell of your building can be translated and explained in seconds.

Camera translation: menus and signs with Google Lens

Google Lens is one of the most useful tools a traveller can have. Open it (often through the Google app or your phone's camera), choose translate and point the camera at the text. The translation appears on top of the image almost instantly. The same feature is in Google Translate under the camera option.

Ways it helps on the road:

• A restaurant menu in Greek or Portuguese.
• Instructions on a parking machine in Italy.
• The label on something you bought at a pharmacy.
• Museum information boards or a train timetable.

Speaking abroad

In Google Translate's conversation mode, the phone listens to you and the other person in turn and translates both ways. It works well in simple situations: in a taxi, at hotel reception, at a market or when asking for directions. Speak clearly and in short sentences for better results.

Chat-style AI assistants now also have voice modes where you can talk naturally. Many newer phones also include built-in translation features, for example for calls or messages. Read more in AI on your phone.

Many people still like to know a few phrases themselves. AI is a great tutor for this:

Planning a trip with AI

AI is a good source of ideas and a capable itinerary builder. Tell it who is travelling, what you enjoy and how fast you like to go, and ask for a day-by-day plan. It can suggest sights, excursions and a sensible order so you are not criss-crossing the city.

Notice how the prompt ends. AI's knowledge of opening hours, prices and timetables can be out of date or simply wrong. It can even invent a restaurant or a bus route that does not exist. Use the plan as a framework and check the details on official websites.

Handling paperwork in another language

Translation is not just for holidays. You may need it for a rental agreement for a flat in Spain, a Finnish letter from the tax office or the return instructions from a German online shop. AI can translate and explain what the text is actually asking you to do.

Be alert to travel-related scams, too. Fake rentals created with AI, forged airline messages and smoothly written "booking confirmations" have become more common. Read more in AI scams.

What translation AI still gets wrong

• Dialects and slang still cause errors – in Finnish and in other languages.
• Tone and politeness can miss the mark. In Japan or Germany formality matters, and the machine is not always right.
• Handwriting and poor lighting weaken camera translation.
• Culture does not translate by machine. AI can tell you about customs, but a local person knows best.

Even so, translation tools are a huge help for travellers. A smile, good manners and a few words you have learned yourself, combined with your phone, go a surprisingly long way. If you want to learn a language properly, see Learning and hobbies.
