Live interpretation, without the interpreter booth
Speak the translation into your phone — your audience listens on theirs, through their own headphones, in real time. No transmitters or receivers to hand out and collect.
How it works
Create a broadcast room
Open SpeakMic, start a Broadcast room, and optionally set a PIN so only your audience can join.
Share the link or QR code
Display the QR code on a screen or print it on a handout — listeners scan it and join in seconds, no app required.
Interpret live
Speak the translation into your phone's microphone. Everyone connected hears you instantly through their own headphones.

No installation needed
Listeners just need a browser — no app store, no download, works on any phone.
Frequently asked questions
Can I interpret into several languages at once?
Yes. Create one broadcast room per language, each with its own interpreter. Listeners choose a language by scanning that room's QR code — print or show the codes side by side, labelled with the language.
How much delay do listeners hear?
Typically 100–500 ms, well under a second — listeners follow the interpreter without a noticeable lag.
Do listeners need headphones?
For interpretation, yes: their own wired or Bluetooth earbuds, so the translation doesn't disturb the people listening to the original.
How much mobile data does listening use?
Speech is sent at about 24 kbps at the default quality — roughly 15 MB per hour per listener, so the venue's WiFi or mobile data both work.
Can more than 100 people listen to one interpreter?
Yes. A room takes up to 100 listeners; relay rooms rebroadcast it to up to 600 in total.
