Camb AI

Camb AI is a text-to-speech plugin. It synthesizes the LLM’s reply into natural-sounding speech via the CambAI MARS TTS API.

Setup

Set your Camb AI API key in the worker environment. Generate a key from the Camb AI studio:

export CAMBAI_API_KEY=<key>

Import the plugin and pass it to the pipeline’s tts slot.

from zrt.plugins import CambAITTS

tts = CambAITTS()

# Pipeline(tts=tts, ...)

Parameter	Type	Default	Description
`api_key`	`str \| None`	`None`	CambAI API key. Falls back to the `CAMBAI_API_KEY` environment variable when unset.
`voice`	`int`	`147320`	Integer voice identifier from the CambAI voice catalog. Numeric IDs can be retrieved from the CambAI dashboard or the voices API endpoint.
`model`	`str`	`"mars-pro"`	CambAI TTS model name. `"mars-pro"` is the primary MARS 8 high-quality model.
`sample_rate`	`int`	`24000`	PCM output sample rate in Hz.

Synthesized audio is streamed back to the caller after the LLM produces a response.
