Sprechen sie Siri?
The late, great writer Douglas Adams imagined a translation tool called the Babel Fish, a fish that you stuck in your ear to understand any language. Your Apple Watch is similar, and you don’t need to stick it anywhere. Just say to Siri, “How do I say [thing you want to say] in [chosen language]?” and Siri will show you and also say the word or phrase aloud.
Siri’s translation features are best for quick queries. If you want real–time translation, use Apple’s Translate app on your iPhone. This enables you to type or talk, automatically translating into your chosen language. If you’re speaking it will read the results aloud, and if you put it into Conversation Mode it’ll listen to two speakers and play a translation of what each person has just said.
