OpenRouter Text to Speech Configuration

OpenRouter can serve text-to-speech models from several providers through one API key.

​

Before you start

Create an account at openrouter.ai and generate an API key under Keys.

​

Required Fields

​

API Key *

Your OpenRouter API key. Keys begin with sk-or-.

​

Model Name *

The speech model in OpenRouter’s provider/model form, for example openai/gpt-4o-mini-tts-2025-12-15. Browse the OpenRouter models page for what is currently offered.

​

Optional Fields

​

Voice

The voice used for the generated speech. The values available depend on the upstream model you route to.

​

Audio Format

The container format of the returned audio, such as mp3, opus, aac, flac, wav, or pcm. Choose mp3 unless you have a reason not to; it is the most widely playable.

​

Model Friendly Name

A label shown in the PipesHub interface so you can tell several configurations apart.
