Inworld acquires Ultravox, combining voice generation with full voice-agent stack
Scobleizer · x · 2026-10-01
- Inworld has acquired Ultravox, a full voice-agent platform; part of the Ultravox team is joining Inworld.
- Ultravox understands intent, reasons, calls tools, completes tasks, and handles turn-taking and interruptions in real time.
- Inworld's Realtime TTS-2 tops Artificial Analysis rankings, supports 200+ languages, responds in under 100 ms, and can be directed via plain English.
- The merger puts both halves of a conversation — the voice and the decision-making — under one roof, targeting AI companions, tutors, and customer-service agents. Existing Ultravox users need no changes since built-in Inworld voices already run on TTS-2.
