If you've ever needed to call someone who doesn't speak your language — a hotel in Japan, a supplier in Germany, a family member in Mexico — you've probably searched for an app that can help. There are several options. They are not equal.
Here's a practical comparison of the five most-used AI phone call translation apps in 2025.
1. AI Call: Phone Translator & Agent
Best for: Real-time phone call translation across any languages.
AI Call puts live interpreting and an AI calling agent right into your phone. During any call, it translates both ways in real time and, if you choose, can speak for you to complete tasks. When the call ends, AI Call automatically produces a clear summary, decision highlights, to-dos, and a full transcript.
Core features
- 🔊 Real-time voice translation: 100+ languages, low latency, clear audio; detects languages and adapts to pace.
- 🤖 Hands-off AI calling: Tell the AI your goal ("reschedule my flight"), constraints, and preferences; it handles the conversation end-to-end.
- 🧑⚖️ Human-in-the-Loop: When details are missing, AI prompts you mid-call for quick input so you keep control.
- 📝 Auto summaries & transcripts: Get a structured recap with outcomes and next steps immediately after every call.
Popular use cases
- Customer service: refunds, billing questions, warranty/returns, itinerary changes
- Bookings & errands: restaurants, clinics, salons, repairs, home services
- Business & sales: cross-border clients, order confirmations, logistics details
- Travel abroad: hotels, taxis, attractions, emergencies in another language
- Phone anxiety: let AI start the call; step in any time
Platform: iOS and Android Languages: 100+ Unique advantage: Only one caller needs the app installed. Pricing: Free trial, then affordable subscription plans.

2. Google Translate (Call Feature on Pixel)
Available on Pixel devices via Google Translate's built-in calling feature. Useful for quick translations, but tied exclusively to Pixel hardware — if you don't own one, this option isn't available to you.
- Platform: Android (Pixel only)
- Languages: ~40
- Pricing: Free
3. Skype Translator
Built into the Skype app, supporting voice and video calls in 60+ languages. The limitation is significant: it only works inside Skype. You cannot use it to call regular phone numbers or people who don't have Skype installed.
- Platform: iOS, Android, Desktop
- Languages: 60+
- Pricing: Free with Skype account
4. Viber Translate Plugin
Works inside the Viber messaging app and can translate messages into 50+ languages. It does not support full real-time phone call translation — it's primarily a messaging translation feature, not a calling one.
- Platform: iOS, Android
- Languages: 50+
- Pricing: Free
5. iTranslate Converse
A popular translation app focused on face-to-face conversations — you hold the phone between two people and speak. It works well for in-person situations but is not designed for phone calls.
- Platform: iOS, Android
- Languages: 100+
- Pricing: Subscription required
