ResembleAI/chatterbox-turbo
Chatterbox is a family of three state-of-the-art, open-source text-to-speech models by Resemble AI. We are excited to introduce Chatterbox-Turbo, our most efficient model yet. Built on a streamlined 350M parameter architecture, Turbo delivers high-quality speech with less compute and VRAM than our previous models. We have also distilled the speech-token-to-mel decoder, previously a bottleneck, reducing generation from 10 steps to just one, while retaining high-fidelity audio output. Paralinguistic tags are now native to the Turbo model, allowing you to use [cough], [laugh], [chuckle], and more to add distinct realism. While Turbo was built primarily for low-latency voice agents, it excels at narration and creative workflows. If you like the model but need to scale or tune it for higher accuracy, check out our competitively priced TTS service (link).
Try the model with a sample request using the same API shape shown in the reference page.
Voice ID created on whollyapi. (Default: empty)
Text to convert to speech
Exaggeration factor for the speech (Default: 0, 0 ≤ exaggeration ≤ 1)
CFG factor for the speech (Default: 0, 0 ≤ cfg ≤ 1)
Language code for multilingual model (e.g., 'en', 'fr', 'zh'). Only used with chatterbox-multilingual.. (Default: empty)
Temperature for the speech (Default: 0.8, 0 ≤ temperature ≤ 2)
Select the desired format for the speech output. Supported formats include mp3, opus, flac, wav, and pcm.
The service tier used for processing the request. When set to 'priority', the request will be processed with higher priority (only applies to models that support it).
Top P for the speech (Default: 0.95, 0 ≤ top_p ≤ 1)
Repetition Penalty for the speech (Default: 1.2, 0 ≤ repetition_penalty ≤ 5)
Top K for the speech (Default: 1000, 0 ≤ top_k ≤ 1000)
Min P for the speech (Default: 0, 0 ≤ min_p ≤ 1)
Seed for the random number generator (Default: empty, 0 ≤ seed ≤ 2147483647)
Adjust settings and run the demo to see the model output generated here in real-time.
