Professional simultaneous interpretation platform
Human interpretation, on every attendee's phone.
LiveMurmur lets your Agency deliver live simultaneous interpretation by professional Interpreters straight to attendees' own phones. They scan a QR, pick a language and listen with their own headphones. No receivers, no app download, no login.
Interpreted by people. LiveMurmur carries the Interpreter's voice; it does not translate, caption or synthesize speech.
Receivers were the hard part.
Attendees already carry a phone and headphones. LiveMurmur uses them, so the equipment table, the queue and the lost-unit count disappear.
HaulingCases of receivers and headsets to charge, carry and ship to every venue.
Handing out and collectingA table at the door, a sign-in sheet, and a count at the end that rarely matches.
Cleaning and replacingSanitizing every unit after use, and buying the ones that walk away.

Built for agencies to run themselves
LiveMurmur is not a managed service or a generic streaming tool. Your team owns the Event from setup to the usage report.
Preflight with OverrideEach Room is checked before going live: original audio connected, every language staffed, link working. The operator can override a failed check deliberately.
Real audio hardwareThe Interpreter app takes the built-in mic, Bluetooth or a USB-C interface, with Voice Clarity processing and a safe bypass.
Original audio as a ChannelThe floor is a first-class Channel, for remote attendees and the hard of hearing.
Parallel RoomsOne Event, many Rooms, each with its own languages, Interpreters and QR.
TakeoverIf an Interpreter's phone fails, another assigned device takes the Channel in seconds. Listeners reconnect on their own.
Anonymous ListenersNo names, emails or accounts. No personal data stored.
Anywhere with internetSpeakers, Interpreters and attendees can be in the hall, in another city or at home.
