OpenVox

What OpenVox is

OpenVox provides local AI tools for text-to-speech, transcription, dubbing, and voice conversion across Android, iOS, macOS, Windows, and API access. For core voice processing, the maker says scripts, voice samples, and generated audio remain on the device. Core generation works offline after a one-time model download. Its audiobook tools import EPUB, PDF, or text and include chapter management for long-form narration. The app can transcribe audio or video into editable text and timestamped subtitles, and dub dialogue while preserving its original timing. The maker lists models covering 646 languages for OmniVoice, 99 transcription languages for Whisper Large v3 Turbo, and 100 translation languages for M2M100. The free tier provides 5,000 characters per day, three voice clones, 10 saved designs, WAV export, and 100 seconds of daily voice conversion; batch generation is excluded. OpenVox Pro is listed at $19.99 a month, described as a one-time purchase per platform, with unlimited generations, long-form and batch generation, and WAV, MP3, and M4A export. Pro includes commercial use. Local API and MCP server features are available on macOS and Windows.
