Beyond silence
Combines voice activity with how a sentence sounds to tell a pause from an ending.
Turn detection · VoxVane Turn Preview
Knows when it is your turn.
Turn detection listens to how people speak, not just to silence, so agents reply quickly without talking over anyone.

Features
What you get.
Profiles
Snappy, balanced or patient, chosen per agent.
Barge-in
Stops speaking when the caller starts, and picks up where it makes sense.
Built into agents
Every Voice Agent session uses it; no extra integration.
Example request
Try it from your terminal.
Every example uses plain HTTPS. Set VOXVANE_API_KEY in your environment first.
