About this app

Sizial Vox turns your smartphone into a modern internet walkie-talkie.

Press the PTT button, speak, and people in your channel hear you almost instantly. No dialing, no waiting for someone to answer, and no long voice messages.

Vox is made for teams, friends, families, trips, events, field work, and any situation where fast voice communication matters.

Instant Push-to-Talk

Use Vox like a traditional walkie-talkie:

press → speak → release.

There is no need to start a regular phone or internet call every time you want to say something.

Private and Group Communication

Talk one-to-one or communicate with multiple people through groups and channels.

Organize conversations for teams, projects, events, trips, or everyday communication.

Communication Channels

Create persistent channels for people you need to stay connected with regularly.

Join a channel and use Vox like a real walkie-talkie — only over the internet.

Fast Voice Transmission

Sizial Vox is designed to minimize the delay between pressing the PTT button and transmitting your voice.

It is especially useful when information needs to be delivered quickly.

Works Over the Internet
