    Inworld acquires realtime voice agent platform Ultravox

    Inworld has announced the acquisition of Ultravox, a realtime voice agent platform; the Ultravox team has joined Inworld and continues to develop the platform. The first update after the acquisition is that the built-in Inworld voice in Ultravox now uses Realtime TTS-2, existing voice IDs remain usable with no code changes, and the upgrade costs nothing extra.

    Why it matters: The acquisition brings voice understanding, reasoning and voice generation into one realtime inference infrastructure, letting readers judge how the voice agent stack is consolidating.

    Inworld cuts prices across its voice and LLM stack, by more than half for most developers

    Inworld announced price cuts across its entire voice stack, with most developers seeing reductions of more than half at each layer of text-to-speech, speech recognition, LLMs and compute. The new prices are already in effect for all developers. Realtime TTS-2 drops to about $10/1M characters, speech recognition to about $0.10/hour, and Router can connect to 100+ models with no markup on third-party models.

    Why it matters: Inworld has lowered prices at every layer of its voice stack and published tiered per-unit rates for TTS, speech recognition and LLMs, which can be used to estimate inference costs for consumer-grade applications.
