Model Overview

Chatterbox is a production-grade, open-source Text-to-Speech (TTS) model that generates expressive and natural-sounding speech. It stands out with its unique emotion control capabilities and the ability to perform instant voice cloning from short audio samples. It also features built-in watermarking for responsible AI.

Best At

• Generating high-quality, natural-sounding speech from text.
• Voice cloning from short audio samples for a personalized touch.
• Fine-tuning speech expressiveness through emotion and exaggeration controls.
• Applications requiring natural voiceovers like memes, videos, games, and AI agents.

Limitations / Not Good At

• While powerful, extreme values for exaggeration can lead to unstable results.
• Not designed for generating music or sound effects.

Ideal Use Cases

• Creating voiceovers for videos and presentations.
• Developing AI agents and chatbots with natural conversational voices.
• Generating audio content for games and interactive media.
• Rapid prototyping of voice applications using voice cloning.
• Podcasting and audiobook narration.

Input & Output Format

• Input: Text prompt (string), optional audio prompt (string URI for voice cloning), and various numerical parameters for fine-tuning (exaggeration, cfg_weight, temperature, seed).
• Output: Synthesized speech as an audio file (string URI).

Performance Notes

• Offers ultra-low latency (sub 200ms) for production use.
• Outputs are watermarked using Resemble AI's Perth (Perceptual Threshold) Watermarker, which is robust against audio editing and compression.
