Serverless Edge TTS API

This project demonstrates how to run Edge TTS as a serverless API using Cerebrium

Overview

The main.py file contains a function run that takes a text input and an optional voice parameter to generate audio and subtitles using Edge TTS. This example specifically streams the output.

Installation

  1. pip install cerebrium
  2. cerebrium login
  3. Make sure you are in the serverless-api folder and run cerebrium deploy

Usage

Once deployed, you should be able to make a curl request similar to the below. You can find this url on your Cerebrium dashboard.

curl --location 'https://api.cortex.cerebrium.ai/v4/p-xxxxxx/serverless-api/run' \
--header 'Authorization: Bearer <AUTH_TOKEN>' \
--header 'Content-Type: application/json' \
--data '{"text": "Tell me something"}'

The run function takes two parameters:

  • text (str): The text to be converted to speech
  • voice (str, optional): The voice to use for TTS (default: "en-GB-SoniaNeural")

It returns a dictionary containing:

  • audio_data: The generated audio as a base64-encoded string
  • subtitles: The generated subtitles in WebVTT format
