# Chatterbox TTS

**Badge:** New  
**Node type:** `audio:chatterbox_tts`  
**Category:** `audio`

## Description

Chatterbox — expressive text-to-speech with voice cloning

## Pricing

- **Cost:** ~3 credits per seconds
- **Per-second rate:** The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.

## Canvas ports

These appear as port handles on the left side of the node.
