Inworld, founded by former Google DeepMind and Dialogflow engineers including CEO Kylan Gibbs, builds realtime voice AI for conversational agents, with its Realtime TTS-2 model reading both what to say and the emotional context and pacing of how to say it, preserving one consistent voice identity across more than 100 languages.
The company has raised more than $117 million at a $500 million valuation from investors including Lightspeed, Kleiner Perkins, and Eric Schmidt's First Spark Ventures, and in mid-2026 cut prices by more than 50% across every pricing tier, aiming to remove cost as the main barrier standing between developers and production voice AI.
Realtime TTS-2 starts around $10 per million characters, with a lower-cost TTS-1.5 Mini tier around $5 per million characters, roughly half the published rate of comparable premium voice models. For a developer building conversational AI agents that need emotionally aware, multilingual voice output at a lower cost than premium competitors, Inworld's recent price cuts address that directly.
