You can ask Siri to translate English into another language.
Simply say “Translate” before the phrase or word you want Siri to translate and end the sentence with a language, e.g. “to French.” Similar phrasings work, too – try asking “how do you say X in Spanish,” for example.
Siri will respond out loud with the translation. It’s great when traveling if you’re trying to communicate to someone that doesn’t speak English. Unfortunately, it won’t translate into English, so it might be a one-sided conversation.
Compatible languages include Mandarin, French, German, Italian, and Spanish.
