Translate a Signal call on your phone
Use the Whisperr app on iPhone or Android, on the same phone as your call.
- 1
Start your Signal call on speaker
Open the conversation in Signal and tap the phone icon or the camera icon. Then turn on the speaker. No phone app can capture a call on the same phone, so Whisperr listens through the microphone.
- 2
Turn Echo Cancellation off
In Whisperr, open Settings and find it under Transcription Settings. With it off, Whisperr can hear the voice coming from your phone’s speaker.
- 3
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.
Translate a Signal call on your computer
Run Signal Desktop and the Whisperr desktop app side by side on your Mac or Windows computer.
- 1
Start the call in Signal on your computer
Signal Desktop needs Signal on your phone first. Link it once, then call from your computer as usual.
- 2
Open the Whisperr desktop app and choose System audio
System audio lets Whisperr hear the call directly from your Mac or Windows computer. Then pick the language being spoken and the one you want to read.
- 3
Press Record and read in real time
The other person’s words appear translated on your screen. Choose Mic + System audio to include your own voice.

Calls where you have to be careful
Whisperr needs the call’s audio to translate it. Read the privacy answer below before you use it, and ask the other person first.
Simple to start
All you need is a phone or a computer.
- 1
Open Whisperr
Use the web app in your browser, or the iPhone, Android, Mac or Windows app.
- 2
Pick your languages and audio
Choose the language being spoken and the one to translate into, then use your microphone — or the audio playing on your computer.
- 3
Just listen, or just speak
Translations appear as people talk. To share them, send the room link or show the QR code.
Whisperr is available everywhere
Use it in your browser, or download the app for your phone or computer.
Privacy first
Whisperr translates your conversations without keeping them.
Audio is never stored
Your audio is processed in real time to produce the transcript and translation, then discarded.
Nothing saved unless you choose
Transcripts and translations are not stored on our servers unless you turn on Save to Cloud.
Never used to train AI
Your audio, transcripts and translations are never used to train AI models, and our service providers can't use them either.
Encrypted in transit
Everything between your device and Whisperr is encrypted with TLS 1.2 or higher.

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.”
