LiteLLM Proxy Text to Speech Configuration

Novaplan AI can turn AI responses into spoken audio through a LiteLLM Proxy instance, using the same gateway that serves your chat and embedding models.

​

Before you start

Your LiteLLM Proxy needs at least one text-to-speech model in its model_list. See LiteLLM Proxy for text generation for setup.

​

Required Fields

​

Endpoint URL *

The address of your LiteLLM Proxy. Default: http://host.docker.internal:4000 Use the proxy URL that Novaplan confirms is reachable from the managed workspace. The default host.docker.internal works only in a compatible network setup; your computer’s localhost is not a workspace endpoint.

​

API Key *

The master key or a virtual key from your LiteLLM Proxy.

​

Model Name *

The speech model as named in your proxy configuration, for example tts-1 or tts-1-hd.

​

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 Novaplan AI interface so you can tell several configurations apart.
