Quick answer
The best real-time translation app depends on what you actually need to translate:
- Live phone calls → AI Call (purpose-built, both sides, 100+ languages)
- Text and signs → Google Translate, DeepL
- In-person speech → Google Translate, Apple Translate
- Live video calls → AI Call (subtitles + two-way voice)
If your real need is talking to a real person on the phone across languages, a phone call translator is the category that matters—most general apps do not handle live calls at all.

What "real-time" really means
Real-time translation means the translation keeps up with a live conversation—usually under about half a second of delay. That is easy for text and hard for live calls, which is why most apps stop at text or in-person mode.
A true real-time app for calls needs speech recognition, neural translation, and natural voice output to all complete fast enough that turn-taking still feels natural. See call translation for how the pipeline works.
Best for live phone calls: AI Call
AI Call is the only option in this list built specifically for live phone calls to real numbers:
- translates both sides in under 0.5 seconds
- works on mobile, landline, and VoIP numbers
- the other person needs no app
- 100+ languages, with transcripts
This is the core real-time translator use case for calls.
Best for text and documents: Google Translate & DeepL
For written translation, Google Translate (broadest coverage) and DeepL (nuanced European languages) remain the leaders. They are not phone call translators, but they are excellent for messages, signs, and documents.
Best for in-person speech: Google Translate & Apple Translate
For face-to-face conversation on one device, Google Translate and Apple Translate conversation modes work well. AI Call also offers a face-to-face mode, but built-in apps are convenient for quick in-person exchanges.
