Model Card

By ContextBoxAI, published under apache-2.0, revision 9f210d622209.

Fine-tuned Vietnamese Kokoro TTS artifacts. - kokorovi.pth: PyTorch Kokoro KModel checkpoint for inference. - kokorovi.onnx: ONNX Runtime export of the acoustic model. - kokorovivoicepack.pt: default Vietnamese voicepack. - config.json: Kokoro config/vocab used by both PyTorch and ONNX inference. - voicepacks/.pt: additional Vietnamese voicepacks. The ONNX CLI downloads kokorovi.onnx, kokorovivoicepack.pt, and config.json from this repository when local paths are not provided. Install onnxruntime-gpu and pass --device cuda to use CUDAExecutionProvider when available. Vietnamese G2P is handled by vig2p, matching the GitHub inference and training code.

Kokoro-82M

Hexgrad

Kokoro is an open-weight TTS model with 82 million parameters. Despite its lightweight architecture, it delivers comparable quality to larger models while being significantly faster and more cost-efficient. With Apache-licensed weights, Kokoro can be deployed anywhere from production environments to personal projects. You can run this basic cell on Google Colab. Listen to samples. For more languages and details, see Advanced Usage. Under the hood, kokoro uses misaki, a G2P library at https://github.com/hexgrad/misaki Model SHA256 Hash: 496dba118d1a58f5f3db2efc88dbdc216e0483fc89fe6e47ee1f2c53f18ad1e4 Data: Kokoro was trained exclusively on permissive/non-copyrighted audio data and IPA…

Resemble AI

Chatterbox Multilingual V3 is the latest general-purpose multilingual TTS model in the Chatterbox family. It keeps the same 0.5B model size while improving speaker similarity, reducing hallucinations, and producing more natural, conversational speech across languages. V3 is designed for broad language coverage like V2, but with stronger stability and more expressive generation. It is the recommended multilingual model for users who want one voice cloning model that works across many languages. Try it in the Chatterbox Multilingual TTS V3 Space. Alongside V3, we are releasing the Single Language Pack: dedicated finetunes for priority languages where tighter quality control, stronger…

Kokoro-82M-v1.0-ONNX

ONNX Community

Kokoro is a frontier TTS model for its size of 82 million parameters (text in/audio out). First, install the kokoro-js library from NPM using: You can then generate speech as follows: Optionally, save the audio to a file: The model is resilient to quantization, enabling efficient high-quality speech synthesis at a fraction of the original model size.
