# Getting Started

This page will help you get started with our Text-to-Speech API.

* Use [/stream](/reference/stream) for short (up to 1,000 characters), time-sensitive cases (e.g. chatbot).
* Use [/speech](/reference/speech) for medium (up to 3,000 characters) use cases.
* Use [/synthesisTasks](/reference/synthesistasks) for longer tasks (e.g. audiobook).

# API Keys
