CometAPI - Zero Runtime

CometAPI is a text-to-speech plugin. It runs CometAPI’s OpenAI-compatible speech API, which is handy if you already use CometAPI and want OpenAI-style voices on the same key.

Setup

Set your CometAPI API key in the worker environment. Generate a key from the CometAPI site:

export COMETAPI_API_KEY=<key>

Usage

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

from zeroruntime.plugins import CometAPITTS

tts = CometAPITTS()

# Pipeline(tts=tts, ...)

import { CometAPITTS } from '@zeroruntime/js-sdk/plugins';

const tts = CometAPITTS();

// Pipeline({ tts, ... })

Parameters

Constructor parameters for CometAPITTS.

Parameter	Type	Default	Description
`api_key`	`str`	`None`	CometAPI API key. Falls back to the `COMETAPI_API_KEY` environment variable when unset.
`model`	`str`	`"tts-1"`	Voice model to synthesize with, e.g. “tts-1” or “tts-1-hd”.
`voice`	`str`	`"alloy"`	Voice name, e.g. “alloy”, “echo”, “nova” or “shimmer”.
`speed`	`float`	`1.0`	Speaking rate multiplier, 0.25 to 4.0, where 1.0 is normal speed.
`response_format`	`str`	`"pcm"`	Audio format of the synthesized speech, e.g. “pcm”.
`chunked_synthesis`	`bool`	`False`	Set to True to synthesize each sentence chunk as a separate request instead of one request per utterance.

Import paths

SDK	Import	Constructor
Python	`from zeroruntime.plugins import CometAPITTS`	`CometAPITTS()`
Node JS	`import { CometAPITTS } from '@zeroruntime/js-sdk/plugins'`	`CometAPITTS()`

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