What iPhone Translate can do
Apple's built-in Translate app (available since iOS 14) handles several scenarios well:
- Face-to-face conversation: You hold your phone between two people; each speaks in their language and hears the reply in theirs. Works in 20 languages.
- Text translation: Type or paste text for instant translation.
- Voice input: Speak a phrase and it translates to text and speech.
- On-device mode: Translate offline without sending data to Apple's servers.
For quick translations at a market, airport, or hotel lobby, iPhone Translate is convenient because it is already installed.
What iPhone Translate cannot do
iPhone Translate has no integration with the Phone app. When you make or receive a phone call, Translate is completely separate — you cannot run both simultaneously. There is no mechanism to route call audio through the translation engine and deliver the output to the other person.
The same limitation applies to Siri: it can answer "how do I say X in Japanese?" but cannot translate a live call in real time.
The gap: live phone calls
Making a call to someone who speaks a different language requires a fundamentally different architecture — one that:
- Captures outgoing voice and translates it in under 500ms
- Delivers the translated audio to the person on the other end
- Captures their reply and translates it back to you in real time
- Does all of this continuously for a multi-minute conversation
No Apple native tool does this. AI Call does.
AI Call on iPhone
AI Call is available on the App Store and integrates with your iPhone's phone system. When you want to call someone in another language:
- Open AI Call
- Select the other person's language
- Dial their number directly from the app
- Speak normally — AI Call handles everything
The other person receives a regular phone call. They hear you in their language; you hear them in yours.
Beyond calls, AI Call also handles face-to-face translation (similar to iPhone Translate, but in 100+ languages), voice and video calls with live subtitles, and AI SMS.
