Caether Becomes the Voice of Vox

Vox is bringing Caether Voice to its entire agent platform — frontier speech-to-speech for millions of conversations every day.

Create API key

Starting today, every voice agent built on Vox can run on Caether Voice — our enterprise-grade speech stack with sub-second latency and natural intonation across 25+ languages.

The partnership pairs Vox's orchestration layer with Caether's real-time models, so teams can ship production voice agents for support, sales, and scheduling without stitching together multiple vendors.

Why it matters

Voice is the most natural interface, but quality and latency have always been the bottleneck. Caether Voice closes that gap — full-duplex turn-taking, barge-in support, and speech tags for tone, pauses, and emphasis.

  • Sub-second median latency, fast enough for real conversations
  • 80+ natural voices, custom voice cloning available
  • Tool calling and session control mid-conversation

Vox agents will roll over to Caether Voice automatically over the coming weeks, with no code changes required.
