  title: Camb.AI Dubbing Voices API
  description: 'The Camb.AI API provides generative voice AI - text-to-speech, dubbing, translation, voice discovery and cloning, and transcription - powered by the MARS (speech / voice) and BOLI (translation) research models. The REST API is served from https://client.camb.ai/apis and authenticated with an x-api-key header. Most operations are asynchronous: a POST starts a task and returns a task_id, the task is polled with a GET until its status is SUCCESS, and the result (audio, transcript, or translation) is then retrieved. Real-time streaming for TTS, transcription, and speech-to-speech translation is offered over separate public WebSocket channels (see the companion AsyncAPI document). Endpoint paths are grounded in the public documentation at https://docs.camb.ai; request and response schemas below are modeled from the documented parameters and may be simplified.'
