Coach the whole group on the move, without shouting
On the slope, on the bike or on the water, you talk normally into your phone and the group hears you through their earbuds — tips, directions, "stop at the next junction".
How it works
Start a broadcast room
A permanent room for your classes — the same QR code every session.
Group scans before you set off
They join in the phone's browser, with no app or account.
Talk as you go
A headset with a microphone keeps your hands free on the poles or the handlebars.
Why instructors use SpeakMic
The whole group at once
Up to 100 listeners — a ski class, a cycling group or a kayak tour.
No radio range
As long as everyone has mobile signal, the group can spread out along the route.
One room for every class
Permanent rooms keep the same link and QR code from season to season.
Frequently asked questions
Is it safe to wear earbuds while skiing or cycling?
Keep the volume low or use one earbud, so riders still hear traffic and the people around them, and follow local rules — some places restrict headphones while cycling.
Can the group answer back?
A broadcast is one-way. For a group that should talk back, use a walkie-talkie room (up to 20 people), where everyone talks in turn.
What about places without signal?
Online rooms need mobile data. Where there's no coverage, SpeakMic Offline for Android connects the phones directly.
What about water?
Keep your phone in a waterproof case; SpeakMic only needs it switched on with a connection.
