OpenVox AI is a local text-to-speech (TTS) application designed for Mac, Windows, and iPad. It aims to provide privacy-focused AI voice generation with a user-friendly interface, allowing users to create realistic voiceovers, design new voices, clone reference voices, generate multi-speaker conversations, and convert written books into audio.

The toolโ€™s core operations run directly on the userโ€™s device, without requiring cloud-based voice generation. Files, scripts, and generated audio remain local, enhancing privacy and giving users more control over their content. After the one-time model download, core voice generation can work offline, reducing the need for a continuous internet connection.

OpenVox AI offers multiple AI voice models, a wide range of voices, and support for many languages. It also provides functionality for creating custom, reusable voices. The app can convert text files into expressive speech and allows users to control speech parameters such as speed and pitch. For larger projects, OpenVox AI includes batch processing, audiobook workflows, and multi-speaker conversation support.

A voice cloning feature is also included, enabling users to upload or record samples and manage cloned voices locally. On Mac, OpenVox AI is optimized for Apple Silicon. On Windows, it supports NVIDIA CUDA acceleration for faster generation on supported GPUs, while also offering CPU mode for non-NVIDIA systems. On iPad, it brings the local AI voice workflow to a more portable form.

OpenVox AI offers a free download and does not require users to create an account.
