Translate a LINE call on your phone
Use the Whisperr app on iPhone or Android, on the same phone as your call.
- 1
Start your LINE call on speaker
Start a voice or video call from your Home or Chats tab in LINE. Then turn on the speaker. No phone app can capture a call on the same phone, so Whisperr listens through the microphone.

In Whisperr, open Settings and find it under Transcription Settings. With it off, Whisperr can hear the voice coming from your phone’s speaker.

Press Record and read
Choose your two languages, press Record and read the translation as the other person talks. A quiet room gives better results.

What users say
Whisperr review
“I love how easy Whisperr is to use and how it accurately understands and translates text and speech across different languages. It's so effective that even in scenarios where other tools might fail, Whisperr performs perfectly. Additionally, the ability to select languages for translation directly on a phone is fantastic. This feature helps us translate church services, ensuring everyone understands without missing anything important. The initial setup was straightforward, making it smooth to start using immediately.”
Fast Translations and a Clear, Easy-to-Read Layout
“It translated really fast, and the way the text appears on the screen—with its clear layout—is very easy to read.”
Whisperr Delivers Lightning-Fast, Highly Accurate Real-Time Translation
“The translation is extremely fast and accurate; after comparing several programs, I consider Whisperr to be the fastest and most accurate real-time translation app.”
Top-Notch Speech Recognition and Flashcard-Style Translations for Fast Study
“Whisperr's speech recognition and translation quality are both top-notch, and better than similar tools I've tried so far. Beyond that, as a Japanese learner, I especially like how Whisperr displays each sentence and its translation almost like flashcards, with a text-to-speech button for each one. That setup makes studying feel fast and efficient, and it's easy to review sentence by sentence.”
Simple Real-Time Translation for Work
“I like best about Whisperr is that it feels simple and straightforward to use.”
Awesome
“This is very useful, extremely user-friendly, easy to use, and the recognition capability is very precise, with very fast speed. It should be the most accurate and fastest translation I've used so far.”
