KugelAudio is a Y Combinator-backed, Germany-based voice AI company (KugelAudio GmbH) offering low-latency text-to-speech built, trained, and hosted entirely in the European Union. Its kugel-3 and kugel-2-turbo models produce natural speech in 26+ languages with accent and dialect coverage, voice cloning from a short reference sample, per-project pronunciation dictionaries with IPA support, word-level timestamps, and inline break, spell, and prosody tags. The platform positions EU data sovereignty as its core differentiator, operating outside the reach of the US CLOUD Act and offering a direct EU endpoint plus on-premise and dedicated deployment. The developer surface is a REST API for generation, voices, models, and dictionaries plus three WebSocket streaming channels tuned for real-time voice agents, including token-by-token input, barge-in, and up to 20 concurrent contexts per connection. Drop-in compatibility surfaces let ElevenLabs-compatible SDKs, LiveKit, PipeCat, and Vapi integrations point at KugelAudio without rewrites.
