Phone Calls
Translate Phone Calls in Real Time
Call a landlord, a clinic, or family abroad in any language. Put the call on speaker and Whisperr translates both sides of the conversation live. Can’t use the speaker? Take the call in WhatsApp Web or another browser-based calling app instead.
How to translate a phone call
All you need is the call on speaker — Whisperr runs on the same phone.
- 1
Put the call on speaker
Make or answer the call as usual — a regular phone number, WhatsApp, LINE, or FaceTime — and switch it to speakerphone. Can’t use the speaker? Take the call in WhatsApp Web or another browser-based calling app and capture the tab instead (see below).
- 2
Start Whisperr on the same phone
Open Whisperr and turn Echo Cancellation off in Settings, so it hears the caller through the speaker. Pick your two languages, set the arrow between them to ⇄ two-way, keep Microphone as the source, and press record.
- 3
Talk normally and read along
Whisperr hears you and the caller, transcribes each line in the language it was spoken in, and shows the translation underneath in about 0.2 seconds.

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.”
Easy to use
“Whisperr is easy to get started and no hassle at all. A great tool to learn languages and for travelling.”
Exceptional outcomes
“I attempted English to Hindi translation and achieved highly accurate results.”
Amazing
“Using it for Spanish to English and it’s amazing!”
Worth hundreds of thousands of yen
“The same performance as other conversation translation apps. Those charge by the minute, but this one is apparently a one-time purchase, so the value for money is outstanding. Compared with about five similar apps, this one is the best on both performance and price. I wonder whether it was made by a Japanese developer??”
Translated from Japanese
Built for calls
Understand the call, and be understood
A live interpreter for the calls you already make — no special number, no three-way interpreter line.
Both sides on one screen
Two-way mode listens for both of your languages at once, so nobody presses a button between turns. Each line appears in the language it was spoken in, with the translation underneath.
Fast enough for conversation
Translation appears in about 0.2 seconds, so you can answer while the caller is still on the line instead of asking them to repeat.
Far more languages
From Spanish, Japanese, and Hindi to Urdu, Persian, and Bengali — including some that built-in call translators don’t cover.
Send them a link
Turn on Broadcast Mode and text the caller the room link. They read your words in their own language in any browser, or tap Speech mode to hear them — no app or sign-up.
No extra device
Whisperr runs on the phone you’re calling from. Calling from a computer instead? The Mac, Windows, and Web apps capture the call directly.
Nothing changes for the caller
No bot joins, no extra line, no special number. The caller just talks as usual while you read along.
Can’t use the speaker? Take the call in a browser
When the call runs in a browser tab or a desktop app, Whisperr captures its audio directly — no speaker needed, and headphones work.
Take the call in WhatsApp Web or another browser-based calling app — Google Voice, Microsoft Teams, or Messenger — then open the Whisperr Web App in a second tab, choose Screen Capture, and share the call’s tab with its audio. Choose Mic + Screen instead to add your own voice to the transcript as well.
On a Mac or Windows PC you can also use a desktop calling app — WhatsApp, LINE, FaceTime on a Mac, or any other. Choose System audio as the source in the Whisperr desktop app: Whisperr reads the computer’s audio output directly, so the caller’s voice arrives clean.
Whisperr vs your phone’s built-in call translation
Some recent Samsung, Pixel, and iPhone models can translate calls on the device. Here’s where each one fits.
Built-in call translation is handy when your phone model and both of your languages are on the maker’s supported list — and it has one real advantage: the other person hears your words spoken in their language inside the call. Whisperr works beyond that list: any phone, any calling app, far more languages, and a running transcript you can read as the call goes.
| Built-in call translation | Whisperr | |
|---|---|---|
| Phones it works on | Recent models from that maker, with its on-device AI turned on | Any phone, tablet, or computer you already own |
| Languages | A shorter list, set by the phone maker | Around 60 in the web and desktop apps, including many long-tail ones |
| Calling apps | Mainly the phone’s own calling apps | Any call you can put on speaker, plus calls running on a computer |
| Your voice in their language | Spoken into the call automatically | A link they open to read or hear your words in their language |
