What KugelAudio is
KugelAudio is a text-to-speech platform for real-time voice agents, interactive applications, and content-creation tools. Its multilingual model supports 39 languages, and WebSocket streaming sends audio chunks as text arrives token by token. The service offers REST and WebSocket APIs with quickstarts for Python, TypeScript/JavaScript, and Java. Documentation names LiveKit, Pipecat, Vapi, and Cognigy integrations for voice agents and also describes speech-to-text with the luchs-1 model. KugelAudio supports voice cloning and exports WAV, PCM, MP3, µ-law, and a-law files. Hosted speech processing runs in configured EU regions, with EU Sovereign Cloud for EU/EEA customers. The company says text, audio, prompts, and transcripts are deleted after requests, while voice references follow separate rules, and customer content is not used for training or fine-tuning. APIs, web access, and self-hosted deployment are available. The Free tier costs nothing for testing access. Kugel-2-turbo costs €0.04 a month, priced per generated audio minute, and kugel-3 costs €0.07 a month on the same basis.
