Open the free Google Translate app, tap Live translate (or Conversation), choose the two languages, put the phone between you, and take turns speaking. It hears each language and reads the translation out loud.
Option 1: Google Translate (best for face-to-face)
- Install the free Google Translate app on iPhone or Android, and update it to the latest version.
- Tap Live translate at the bottom (on some versions it's called Conversation).
- Pick the two languages, for example English and Spanish.
- Put the phone between you and take turns speaking. It detects who's speaking and plays the translation aloud.
- Tip: Face to face mode splits the screen so each person can read their own language.
Live conversation works in more than 70 languages. Some features, like headphone translation, are still rolling out by country.
Option 2: ChatGPT or Gemini voice (best for help and context)
Open the ChatGPT or Gemini app, start a voice conversation, and say: "Please act as my interpreter between English and [language]. When I speak English, repeat it in [language], and when you hear [language], tell me in English." This is handy when you also want help with what to say, like explaining a symptom or asking for directions politely. Voice use on free plans is limited.
Tips for better translations
- Speak in short, simple sentences and pause between them.
- Avoid slang and idioms. Say "I'm very tired" rather than "I'm beat."
- For important things like medicine or legal documents, ask for a professional interpreter. Many hospitals offer one for free.
Try this prompt (copy and paste)
Please be my interpreter between English and [language]. Keep translations short and natural. When I speak English, say it in [language]. When you hear [language], tell me what was said in simple English. If something is unclear or could be misunderstood, tell me.
